1. Noise generated by air propulsion systems (both jet and fan).
2. Uncomfortable vibrations created by propulsion system.
3. Lack of precision steering, especially over land. Air...
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...
