It is difficult finding a suitable electronic speed controller. only the boat & some car esc's have reverse & everything is radio control. There are various functions needed to be programmed in to the motor controller & some adaptations need to be made to run it off a joy stick. I may have to get an esc taylor made once I know the motor is perfect for the job & I have the stats on it. I have a helicopter / plane transmitter & apparently There are different transmitters for land based units. I am intending to oil compensate but with an air compensation method. I will be using either a relieving type pressure regulator set low, or a modified second stage regulator. so the air will be pressurising the oil to ambient. If the oil runs out I will still have air. I will experiment with oil & air. Any videos of your helicopter action?

The shaft is 8mm inside the motor with a very slight increase in diameter where itmoves out of the motor. At that point there is a flat section for 2 grub screws tosecure it. Then it transitions to 10mm to fit the propeller. And there are a couple ofo-ring grooves as well. I have ordered a "follower" for my lathe to support the rodwhen machining as there is a bit of flex in it.It is an outrunner motor and the can is secured with a number of screws that arelock tighted in. Very hard to remove & I have stuffed threads drilling them out.It is a sensorless motor & most of the BLDC ESC manufacturers (like Kelly) that producecontrollers to operate from joy sticks, don't do much in the way of sensorlesscontrollers in that power range. There may be a way of mounting hall sensors to the?inside of the thruster housing to turn it in to a sensored motor.I need 6 of these initially so it will be worth my while sorting the problems.I get them from either the HK International or Aussie warehouse.There is the Haswing Protruar brushless motor. Emile uses one & said the gearbox was a bit noisy.http://www.haswingmarine.com.au/Protruar-2HP-Electric-Outboard-Motor-Haswing-100lbs-.html If you can hang off a bit, I will do the donkey work on these motors so you can see if it willbe worthwhile. I should have built the housing & done my in pool testingI by the end of the Month.I may be in the position to make some available later down the track.Cheers Alan From: glen brown via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Tuesday, November 3, 2015 5:04 AM Subject: Re: [PSUBS-MAILIST] Alan's thrusters Thanks AlanExtended 8mm shaft that's easy.

Thus, when supplying a drawing or specification, you dimension the inside radii, and then specify the required wall thickness (with tolerance). As the manufacturer, knowing how a part thins during forming, they would then select a plate of sufficient thickness to meet your specification (minimum thickness at apex), resulting in a head which is thicker at the flange. If you drew or specified a maximum thickness tolerance, they would then have to turn it down to meet it (expensive), or you could just accept the extra weight imposed by the thicker flange. As for roundness, whether you measure inside or out is of little consequence. The thinning should not be so profound as to affect the deviation of the neutral axis within the shell wall carrying the hoop stress, but of course it will be at its worst on the outside, so that is the most conservative option, and is also the easiest to measure. They'd have to really mess up to be grossly out on roundness, however apex thinning is always a possible problem, so specifying that minimum thickness is always a good idea. As for me, I figured I should finally step away from the drawing board and get something built, so I will be embarking on a project soon. Stay tuned.

Every opening you cut in the hull shell must be reinforced with additional material to retain the load carrying capacity. The absolute best way to do that is with a monolithic casting, but short of that, cutting a larger opening and welding in a thicker shell pad, tapered back to the main shell, and welded to the window seat with geometry which minimizes stress concentrations is the way to go. If you don't reinforce, you need to derate the entire shell, and are then carrying much more weight than necessary.

The idea with a conical bearing face on a hatch, if you are not trying to establish a metal-to-metal seal, is to provide a load path through the hatch itself to carry the shell stress that would otherwise require heavy reinforcement around the hole. Thus, the "ideal" hatch would be the same thickness and curvature as the shell it is replacing, aligned to it so the load transfers straight through, with a flange on both the hatch and shell parts to create a substantial bearing face. The conical angle in that case would be set by the hatch diameter, as the ideal interface angle would be perpendicular to the shell at every point. I suspect that in practice, the cone is exaggerated beyond that, because we're talking about very small angles on larger spheres - on a PSub, perhaps it is more important. The other advantage is of course the self-centering.

Thus, the "ideal" hatch would be the same thickness and curvature as the shell it is replacing, aligned to it so the load transfers straight through, with a flange on both the hatch and shell parts to create a substantial bearing face. The conical angle in that case would be set by the hatch diameter, as the ideal interface angle would be perpendicular to the shell at every point.

A project we started on was a wreck in 1800ft down a coral reef slope some 200 miles out from Townsville, Australia which was carrying a cargo of zinc ingots worth considerable money at that time. We borrowed the Pisces off Sverker Halstrom and shipped it down from Singapore and loaded it aboard our salvage vessel in Australia having been told it was operational and ready to go. We then found it had not been in water for some 10 years so I spent the next 6 weeks or so decommissioning the sub which was a task especially in the heat and being out at sea in a remote lagoon. Cut a long story short we got the sub in the water and carried out test dives in the lagoon - in the clear tropical water was like flying an airship around the reefs - then started to prepare it for deep dives to the wreck site - but 1991 there was the financial crash, the banks got nervous and pulled the plug on support for our operation - probably a good thing before we started deep dives. I later visited the yard in Singapore where sub was again stored in open, I found the hatch had been left open and in the monsoon rains the sphere had filled with water - at least it was rainwater! Sorry to see after all my hard work in those conditions - but at least it has a good retirement home now in Phil's yard with other friends. As said give her a pat on the backside for me when you visit.

They also do a SS version for several times the price. Global SCUBA Manufacturing makes most of the ones that Alec pointed out at Deep Six and they're pretty good too. Being chrome plated brass they tend to be cheaper than SS, a bit nicer for oxygen service, and are still good for saltwater use. Both of those places only sell through distributors but you should be able to download catalogues (I can send if needed) so you can at least see what exists. I may have already mentioned (shameless plug), but I run a small business on the side which largely deals with custom assemblies and high pressure oxygen fittings, hoses, cylinder adaptors, etc. for SCUBA gas mixing and the like (and I'm a distributor for GSM and Western). My catalogue is here: www.tfmengineering.com.au/TFM Engineering Catalogue 2015-10.pdf Much of my stock comes from the USA (to Australia) so it may not be very effective to ship it here and then back again, but if anyone is interested and has a few hundred USD worth of order I can probably arrange to get stuff sent direct from the factory instead.

If you lost air pressure, these tanks are not designed for external pressure. Steel is cheap. Why not fabricate some 1 arm buoyancy tanks with construction like a conventional internally stiffened 1 atm pressure hull. Use ABS stress spreadsheet to get right shell and stiffener details. You could use OTS semielliptical or hemi heads. The would be relatively cheap compared to syntactic foam. With your welding skills, this would be easy.

I presume you mean to employ these as hard / variable buoyancy tanks? With the active pressure compensation, you need to consider the consequences of a failure in the compensation system. An imploded buoyancy tank could have severe consequences. If looking for permanent buoyancy, syntactic foam is highly unlikely to fail unexpectedly.

Composite hulls usually require verification of theoretical results by physical testing. As for the theory, fiber reinforced matrix composites usually exhibit properties which are weighted averages of the individual component properties in proportion to their volume fractions, but they have failure modes which homogeneous isotropic materials do not, particularly with respect to buckling, delamination, and brittle fracture. Additional variables such as average length of fiber, the order of consecutive principal fiber orientations, layer thickness and so forth all have an effect on the ultimate part performance, making composite failures less predictable. That said, there have been a number of commercially successful composite pressure hulls, but there is a significant amount of work involved in validating them.

As you get further away from the surface (above or below) they are probably similar. Keeping in mind that it is illegal to bail out of a plane unless it has suffered catastrophic structural failure.

But it's a bit overly paranoid since SS tube is widely used with HP oxygen anyway, and so you have to use SS compression fittings with it. Plus you have to try really hard to get SS going. If you use plenty of Teflon tape, say at least 4-5 turns (and make sure it's suitable for oxygen, and none of it ends up in the flow path) the galling risk of SS on SS new threads is very minimal. Because NPT threads seal on the sharp bit of the threads, they do get slightly more damaged each time they are assembled, so avoid doing it more than necessary, and don't tighten ridiculously hard. That said, with plenty of Teflon tape you can get away with at least 5 cycles. It should go in and turn smoothly as you apply torque, if you feel it getting jerky then that's time to think about stopping. When they gall, it's usually the male thread that's wrecked, so re-tapping the female thread is an option in many cases.

Plus the 1/4" threads are much more forgiving than the bigger ones. I just finished a project (a system for a very large LNG plant for Chevron) where we were not not allowed to use Teflon tape, only paste - and everything was SS. Everything went in fine and sealed, but when we had to make some modifications maybe 40% of the connections were galled to some extent. Damaged threads is something to really watch out for, as that can really ruin your day. This can also happen when a SS threaded fitting is welded onto something and distorts slightly - I had some rather expensive components on a last minute project destroy themselves because of this.

Plus the 1/4" threads are much more forgiving than the bigger ones.I just finished a project (a system for a very large LNG plant for Chevron) where we were not not allowed to use Teflon tape, only paste - and everything was SS. Everything went in fine and sealed, but when we had to make some modifications maybe 40% of the connections were galled to some extent.Damaged threads is something to really watch out for, as that can really ruin your day. This can also happen when a SS threaded fitting is welded onto something and distorts slightly - I had some rather expensive components on a last minute project destroy themselves because of this.Cheers, SteveOn 13/11/2015 1:58 AM, "Brian Cox via Personal_Submersibles" wrote: Stephen,??

But it's a bit overly paranoid since SS tube is widely used with HP oxygen anyway, and so you have to use SS compression fittings with it.? Plus you have to try really hard to get SS going. If you use plenty of Teflon tape, say at least?4-5 turns?(and make sure it's suitable for oxygen, and none of it ends up in the flow path) the galling risk of SS on SS new threads is very minimal.??Because NPT threads seal on the?sharp bit of the threads, they do?get slightly more damaged each time?they are assembled, so avoid doing it more than necessary, and don't tighten ridiculously hard.? That said, with plenty of Teflon tape you can get away with at least 5 cycles. It should go in and turn?smoothly as you apply torque, if you feel it getting jerky then that's time to think about stopping.? When they gall, it's usually the?male thread that's wrecked, so?re-tapping the female thread is an option in many cases.

Both of those places only sell through distributors but you should be able to download?catalogues (I can send if needed) so you can at least see what?exists. I may have already?mentioned?(shameless plug),?but I run a?small business?on the side?which largely deals with custom assemblies and?high pressure oxygen fittings, hoses,?cylinder adaptors, etc. for?SCUBA?gas mixing and the like (and I'm a distributor for GSM and Western).? My catalogue is here: www.tfmengineering.com.au/TFM Engineering Catalogue 2015-10.pdf Much of my stock comes from the USA (to Australia) so it may?not be very effective to?ship it here and then back again, but if anyone is interested and has a?few hundred USD worth of order I can probably arrange to get stuff sent?direct from the factory instead.

Since that release, there have been some minor changes to the layout, some material property updates, and some changes to mass and volume calculations. This version, however, is still limited to spherical, hemispherical and 2:1 semi-ellipsoidal shells. Stiffened cylindrical shells (on which I am still working) will be in the next release. As before, installation is constrained to Windows machines running 64-bit operating systems, and requires the National Instruments LabVIEW Runtime Engine to be installed first. Also, this version requires a different version of the engine than the previous one did. The link to the correct engine is below: http://www.ni.com/download/labview-run-time-engine-2015/5506/en/ After installing the runtime engine, simply extract the attached .ZIP file to run the application.

Hmmm maybe putting pins through would be better than the insulated wires. However with the blue globe cable gland it is the whole cable that goes through. Re the casting; I want to use straight silicone on the cable jacket to give adherence & for it to be able to compress with any compression of the jacket. Then to tidy it up & add a bit more support I will cover it with the "castable rubber". The intention is to make a 2 part mold to form the castable rubber around the cable & threaded adapter ( as per previous dwg ). I need 16 of these for my light fittings & light through hulls & 5 for motors alone. So it will be worth getting it right. The castable rubber can be either sticky or not sticky depending on how much talcum powder you mix. It may be that I cast a semi sticky castable rubber or put a thin layer of silicon over the initial layer, then cast the non sticky castable rubber over that to give some adhesion. Was an artist in a past life, & made moulds & cast resins. So won't be too taxing playing around with this.

I use the 2 part resin which 3M supply with their Scotchcast 82 -A splice kits (don't have resin spec with me at present) but rather than use their 2 piece mould supplied with the kit I use Raychem WCSM heat shrink. A few precautions needed when doing the splice but basically the heat shrink is heated to shrink one end onto cable or connector, then supported vertical with open end of shrink upper. The resin is mixed and poured into the open shrink leaving enough shrink to later heat and close around cable after resin has set. While resin is still in liguid form and setting, hand squeeze the shrink at intervals to burp any air bubbles. After resin set use heat gun to shrink the excess shrine around cable to close off the splice. It works! I have attached photo of some cables and connectors I have spliced - hope this helps - the 3M resin product is not cheap but who wants to be cheap at depth.

My first port of call is to visit a large hydraulicservice & manufacturing plant in case they have something?lying around, or can suggest anything.?I have been reading the penetrator section in"Busby". Apparently the European method is to take the cableright through the penetrator & the American method is to havepins going through. With the European method sometimes theyinject resin under pressure inside the individual wire insulationsto seal them in case the cable is sheared.G.L. require that there is no leak after a cable breakage, so Ithink the pin option is better in that case.?Busby said most of the failures happened at the pin / wiring interface.?I imagine?it would be a weak point if you pulled on the cable.?The idea of supporting this point with the silicone & casting over?the top must have merit.?Some manufacturers brazed washers to the pins to stop them?extruding through the resin. I don't think I need to worry about that at 500ft,?but maybe a few dots of brazing on the pins would help it a bit.Cheers Alan From: hank pronk via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Monday, November 16, 2015 7:46 AM Subject: Re: [PSUBS-MAILIST] Pressure Test Chamber Alan,I was looking around NZ online for a?hydraulic cylinder, you guys have it tough for surplus stuff. ?Hank On Sunday, November 15, 2015 11:04 AM, Alan James via Personal_Submersibles wrote: Thanks Hank,I like your idea of the small air chamber to test the through hulls,I was intending to screw them to the inside of a fitting in the end cap / lid.Will make inquiries re cylinders.Alan From: hank pronk via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Monday, November 16, 2015 2:30 AM Subject: Re: [PSUBS-MAILIST] Pressure Test Chamber Hi alan,My cylinder is very unusual because it is light weight for a crane. ?But yes, you leave the piston in, if it is double acting and either all of the rod or cut the excess off, I would leave it intact. ?I can either use water or air, normally I think you would fill with water for safety also to locate a leak in your test part. ?I use air because the cylinder is safe and rated. ?If you find a double acting cylinder, you can also remove the piston and just use the piston nut and washer to hold the rod in from pushing out. ?Then you can use the second port for filling with water while it vents out the opposite port. ?Then you just need a tee with gauge and valve. ?You can pressurize it with your scuba tank or a pressure washer. ?The scuba tanks make the most sense ?if you fill with water first so you displace all the air. ?You will need to make a small air chamber to go inside if your testing your penetrators. ?Just take a pipe threaded at both ends, screw a cap on one end and a fitting at the other that will except your penetrator. ?

With smaller trawl floats filling thegaps between the bigger ones. Then in stages fill in the gaps with syntactic foam.That should add strength to the trawl floats.

I'm curious about whether the inside-out testing chamber is useful to anyone (and also to heat from Alan about where to get blue globe cable glands down under).Cheers, SteveOn 16/11/2015 1:37 PM, "Stephen Fordyce" wrote: Hey guys, If you're going to make a small pressure chamber to go inside the big one just for testing penetrators, how about just making your small one so that you can screw the penetrator onto the inside of it?See sketch attached.I did this to test some cable gland/penetrators I made for underwater lights and it was very quick and easy to put together, it was small enough that I could use standard black plastic fittings from Bunnings as they were rated to something like 100m water depth.I also found that sealing the end of the cable with liquid electrical tape worked fine to prevent leaks through the cable stands at these pressures (but only for external pressure!).Cheers, StevePS: where/how do you get blue globe cable glands down under??On 16/11/2015 6:38 AM, "Alan James via Personal_Submersibles" wrote: Hank,you are right.

Apparently the European method is to take the cableright through the penetrator & the American method is to havepins going through. With the European method sometimes theyinject resin under pressure inside the individual wire insulationsto seal them in case the cable is sheared.G.L. require that there is no leak after a cable breakage, so Ithink the pin option is better in that case.?Busby said most of the failures happened at the pin / wiring interface.?I imagine?it would be a weak point if you pulled on the cable.?The idea of supporting this point with the silicone & casting over?the top must have merit.?Some manufacturers brazed washers to the pins to stop them?extruding through the resin.

But yes, you leave the piston in, if it is double acting and either all of the rod or cut the excess off, I would leave it intact.? I can either use water or air, normally I think you would fill with water for safety also to locate a leak in your test part.? I use air because the cylinder is safe and rated.? If you find a double acting cylinder, you can also remove the piston and just use the piston nut and washer to hold the rod in from pushing out.? Then you can use the second port for filling with water while it vents out the opposite port.? Then you just need a tee with gauge and valve.? You can pressurize it with your scuba tank or a pressure washer.? The scuba tanks make the most sense ?if you fill with water first so you displace all the air.? You will need to make a small air chamber to go inside if your testing your penetrators.? Just take a pipe threaded at both ends, screw a cap on one end and a fitting at the other that will except your penetrator. ? This way you have water pushing against the penetrator with air on the opposite side of the penetrator.?

It would save using the 4 vertical thrusters,but would only work at speed.If you look at the sub side on, the profile at the front would cause itto nose dive & that would be accentuated by the rear thrusters drivingit down. So the rear spoiler would counter that.Maybe the spoiler could be an add on for David Columbo who has?a similar design.Cheers Alan From: Alec Smyth via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Friday, November 20, 2015 2:39 AM Subject: Re: [PSUBS-MAILIST] Deep Flight Dragon I have to say one thing I wonder about is the function of that rear spoiler.

Theyare the right voltage at 40V & are only 1500W. They are direct drive & getting their torqueby using large diameter narrow motors.There are some good photos of the fuselage & hull in the links on this page.He is not scared to think outside the box.Love a visit to his workshop.

From underwater fighter jets to this underwater race car.? I noticed that there is no photo showing ingress/egress on the surface.? Personal submarines, in my humble opinion, really should have sufficient freeboard (often a conning tower) to allow the pilot to operate the vessel solo (without a launch crew and/or crane).? Maybe this one does, the Super Falcon does not.But is sure looks good enough to get the male youth off the jetski and into a submarine.?

My new sub is going to be ready in time for spring, and Snoopy's berth in the garage is needed to build the new sub's trailer. I just completed a minor overhaul, replacing a speed controller and the insides of both side thrusters. Only the cans were reused, to avoid re-potting the conductors, but the entire insides of the motors are new. The stern thruster has only two summers on it so no need for maintenance at this time. In fact there is no backlog of needed maintenance, everything is functional. She has made dives to 250 feet and has been tested to 400 feet unmanned. A firm prospective buyer is invited to spend an afternoon diving before committing. Here is a list of included equipment: - Extending tongue trailer - SCUBA tanks (2) - O2 tank - External flood lights (4) - Navigational lights - Camera mounts (4) - Scrubber - Cabin pressure gauge - O2 meter - O2 regulator - Built-in breathing supply - Emergency buoy - Depth sounder - Spare air (2) - Fire extinguisher - Trawl floats (6) - 70 lb lead ballast for salt water ops - Compass Relative to a standard K-250, Snoopy has some improvements: - MBT valves are mounted with O-ring sealed through-hulls instead of sealed to the CT with silicone. - Removable bulkhead so you can add or modify penetrators without welding. - Control by portable fly-by-wire box. - Variable speed controllers instead of switches. - Rudder replaced by a stern thruster moved by an electric linear actuator. This frees up the pilot's feet, there are no pedals. - Side thrusters index plates, freeing up the pilot's hands. - Redundant MBTs (standard bow/stern MBTs plus saddle MBTs) - VBT replaced by external trawl float tubes - SCUBA tanks moved outside - 4 batteries instead of 3 - Life support - Cabin over-pressure valve - Dome is sealed with O-ring rather than potted - 100% 316 stainless brackets and mounts - HP MBT air supply, eliminating regulator The PSUBS project page shows much of this: http://www.psubs.org/projects/1234567810/snoopyin2012/ Snoopy will come with checklists, emergency procedures, and log book. The only items NOT included are a Desert Star locator beacon and the OTS communications, because I intend to use them in the new sub. But the through-hull, transducer mount, and a cabin amplifier are ready for you to just plug in your own comms. Here are some videos: https://vimeo.com/131692448 https://vimeo.com/76340636 https://vimeo.com/53131444 https://vimeo.com/18184179 I've asked a few people here what they thought a fair price might be, and the consensus was $25K, so that's what I'm asking.
