For a proposed Hovercraft propulsion system,
1a) Is it feasible to use separate hydraulic motors to power a) four wheels for land propulsion, b) two water propellors for water propulsion c) two lift fans d) six actuators for retracting / deploying the wheels and propellers.
1b) Can the motors produce about 10 - 15 hp of power each, about 150 RPM?
2) Is it feasible to use a 180 hp engine to power a hydraulic pump for all the above? Estimated hovercraft fully loaded weight 3200 pounds, speed 60 mph, hover height 1/2 inch on a 7 inch cushion, 14.5 feet long x 8 feet wide.
3) Do hydraulic pumps have any feedback control mechanism to control the amount of torque delivered by the device (engine) powering them?
4) Can hydraulic motors be deployed underwater ie. to power a water propeller?
5) Do hydraulic pumps come with a pressure regulation / overpressure protection system to allow multiple devices to run at power consumption levels varying over time, as proposed above in items 1,2, and 3?
6) Can the direction of hydraulic fluid be changed while a motor is in full operation?
7) Can hydraulic leaking be minimized?
8) Is environmentally friendly hydraulic fluid available, in case of spills?
Thank you in advance for your patience and assistance. Ron L
