HYDRAULIC AVIATION PROPULSION SYSTEM USING SECONDARY CONTROL DRIVING |
| abstract |
A hydraulic propulsion system includes an input interface configured to receive mechanical power from a power source, a pressure source comprising one or more fixed or variable displacement pumps coupled to the interface of a power source. input and adaptable to convert mechanical power into hydraulic power and control the output pressure of the pressure source (system pressure), one or more variable displacement motors coupled to the pressure source via a line correspondingly high pressure designed to be mechanically coupled to one or more aerodynamic rotors of an aircraft and comprising a closed loop speed control arrangement in response to a controlled rotor speed and a control device adapted to control the speed of a or multiple variable displacement motors by providing a control signal to control the system pressure. |
