Hi SSN626B
The 37 psi figure was calculated from the Calctool which includes atmospheric pressure.
Does the 22psi at 50ft and 14.7psi per 33ft include atmospheric pressure?
In Calctool the atmospheric pressure is about 14.7 psi, so added with the 22 psi would give 36.7psi.
I hope that this is correct as I am designing my ROV based on the calctool pressure results.
Your idea to use the aircraft landing gear is one I will also be looking at.
Many thanks.
