摘要： A method for generating hydraulic power in an aircraft (2), the aircraft having a drive system (4) comprising at least one transmission shaft (10, 14, 44, 46) connected to a power control unit (22, 24), the power control unit having an electric motor (36) and a hydraulic displacement machine (34) connected to a differential gear unit (28) for driving a common output shaft (52), the method comprises the steps of switching the hydraulic displacement machine into a pump mode, arresting the output shaft, rotating the electric motor such that the hydraulic displacement machine is driven due to the arrested output shaft and supplying the fluid flow into a hydraulic system (54). A drive system of an aircraft may thereby used for either moving control surfaces or for generating hydraulic power in an aircraft. This hydraulic power may be used to cover hydraulic load peaks during aircraft operation or to power hydraulic devices without the need of additional hydraulic power generation components.

摘要： An aircraft flap drive system utilized a variable displacement motor (15) having a fluid pressure actuated means (23) to vary the displacement of the motor. The system includes a displacement control valve (41), and an electrohydraulic control means (55,67,85) operable in response to an electrical input signal (91) to communicate pressurized fluid from a source (11) to the motor. The displacement control valve (41) includes a load sensing arrangement (13,53,49) responsive to an increasing load on the motor to bias the displacement control valve toward a position whereby the motor moves toward its maximum displacement (minimum flow). One result is that the conventional fixed displacement motor, of a particular size and weight, may be replaced by a variable motor which is smaller and lighter.

摘要： A control system utilizes hydraulic power only to control a fixed-wing aircraft horizontal stabilizer trim control surface (8) with no electrical control devices except for a cockpit pilot/co-pilot initiated 3-position spring-centered toggle trim switch (11), a backup electrical motor (22) and a standard electronic logic pilot interface. The toggle trim switch (11) controls two solenoid valves (150,152) which control the operation of a directional control valve (140). The control system also includes a hydraulic motor (20), a rate control valve (18), a blocking-bypass valve (160), a shutoff valve (170) with an integrated position sensor and a gear set driving an acme threaded output shaft for elevating or lowering the horizontal stabilizer trim control surface (8) on command by the pilot. The control system controls the horizontal stabilizer trim control surface (8) angular displacement rate as a function of angular position by means of a mechanical feedback linkage (126) between the spool of the rate control valve (18) and the horizontal stabilizer trim control surface (8). The sleeve (102) of the rate control valve (18) has a variable outflow area slot (114,116) to control the hydraulic flow rate to the motor ports of the hydraulic motor (20). The horizontal stabilizer trim control surface (8) is automatically stopped at pre-determined maximum-up/maximum-down positions by means of a mechanical feedback linkage (126) between the horizontal stabilizer trim control surface (8) and the spool of the shutoff valve (170). If the mechanical feedback linkage (126) between the rate control valve (18) spool and the horizontal stabilizer trim control surface (8) malfunctions, the rate control valve (18) automatically reverts to a default fixed flow rate which translates into a corresponding fixed horizontal stabilizer trim control surface (8) angular displacement rate.

摘要： A control system (10) for a limited stall load actuator (60) comprises a servo pressure regulator (20), solenoid valve (40), relief valve (30) and a shuttle valve (50) connected with a piston actuator (60) such that when source pressure P1 is declining the servo pressure regulator (20) will open to permit more flow and maintain a minimum actuation force effected by the actuator (60), and should there occur a failure of the servo pressure regulator (20) that would permit high source pressure to be communicated to the control system (10), the relief valve (30) will operate to limit the amount of high pressure communicated to the control system (10) such that the actuator (60) will attain no greater than a predetermined maximum output force.
