Hello Joe, It ac cured to me that, if there was two foot brakes that control braking flaps, or an emergency brake lever to operate those flaps, it could be wired in so that when both foot peddles are engaged for deploying the braking flaps, and/or the emergency brake flaps lever is pulled, that it would automatically reverse the thruster props. Along this same idea, one could have no braking flaps on a sub at all, and have one foot brake peddle or lever that when engaged will send all the thruster props into reverse.

Minnkota has a dial control that I was looking at. Operationally, the first order of business was going to be target acquisition on the Interphase screen by the pilot, with a visual confirmation or "tally ho" by the co-pilot via a forward cam or port. Then the pilot switches to visual navigation, just like flying an approach on instruments. Basically, the whole idea being to avoid the "oops" in the first place.

Better to pump up the motors than
devise a whole separate system for slowing the sub. A full reverse using maximum
thrust from all your motors would be easier to incorporate, cut down on reaction
time, and have the added benefit of being available for a quick burst of thrust
in forward as well. My motors (4) have 101 pounds thrust each. In reverse,
that's probably a lot less, but still, almost like throwing out an anchor! No
separate complicated system, just slam the controls back and hope you have
enough room to stop. There again, it doesn't make sense to travel faster than
what your sub can handle in a stop mode. Frank D. It's only a deal if it's where you want to go. Find your travel deal here. |
