    摘要: A system for providing sideslip envelope protection includes a processor for obtaining values of a sideslip envelope indicative of operating conditions of the aircraft along an axis and for estimating a sideslip angle along the axis from at least one operating condition; and a comparer for comparing the sideslip angle with the sideslip envelope to generate an output value, where the processor determines a maximum yaw rate from the output value and scales the maximum yaw rate to generate a scaled yaw rate.

    摘要: A backup hydraulic pump (17) supplies pressure oil to an actuator (11a) when a loss or degradation of the function of an aircraft central hydraulic power source (104) occurs. A control valve (15a, 15b) controls the operation of the actuator (11a) by controlling supply and discharge of the pressure oil to/from the actuator (11a). The control valve has a main body (27) provided with a pressure oil port (32a-f), a spool portion (28) that moves in a sliding manner within the main portion and switches a path of the pressure oil, and a drive portion (29). The drive portion (29) is connected to an end of the spool portion (28) and drives the spool portion (28) by electromagnetic force so as to control the position of the spool portion (28) based on an electric signal.
