AIRBORNE VEHICLE Russian patent published in 2015 - IPC B64C27/64 F15B7/04 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to aircraft hydraulic system designs. The airborne vehicle (1) has system (4, 5) to control attitude of flight which system, in its turn, has at least one actuator (6, 7) and hydraulic circuit connected with the actuator (6, 7). The hydraulic circuit includes at least one pump (8) made capable to give the first delivery rate when hydraulic circuit pressure is higher than specified threshold. The pump (8) is made capable to give the second delivery rate which exceeds the first delivery rate, and the airborne vehicle (1) has a sensor (11a, 11b, 12, 13) to detect value connected with hydraulic circuit pressure and programmable central control unit (10) which controls the pump (8) to give the second delivery rate when the value detected by the sensor (11a, 11b, 12, 13) matches hydraulic circuit pressure which is lower than threshold. Hydraulic circuit pressure control method includes detection of value connected with pressure of the mentioned hydraulic circuit, increase of delivery form the mentioned pump when the mentioned value detected by the mentioned sensor matches the pressure of the mentioned hydraulic circuit which is lower than the mentioned threshold.

EFFECT: possibility to modify hydraulic equipment without changing hydraulic circuit.
