摘要： A pump unit installed inside a wing (102) includes a backup hydraulic pump (20) that can supply pressure oil to an actuator (104) when a loss or reduction occurs in the function of an aircraft central hydraulic power source (105) and an electric motor that drives the pump. A wing structure (102) portion forming the surface structure of the wing is provided with an inlet port and an exhaust port that are formed therethrough. The inlet port is provided so as to be opened and closed by an inlet port opening/closing portion, and the exhaust port is provided so as to be opened and closed by an exhaust port opening/closing portion.

摘要： An operation control apparatus includes a command generation portion that generates a command signal for commanding operation of a control surface, and first and second monitoring portions that monitor an abnormality of operation of first and second control portions, respectively, of the actuator control apparatus. The actuator control apparatus includes first and second control portions that generate a control signal for an actuator for driving the control surface and that are different in design, and a switching unit that switches the connection to the actuator from one of the first and second control portions to the other, when an abnormality is detected by the first and second monitoring portions. Accordingly, it is possible to monitor a generic failure, and realize redundancy enabling control of the overall operation of the actuator, from start to finish, when a generic failure has occurred, thus realizing further simplification and streamlining of the configuration.

摘要： A system for detecting mechanical failure of a connection between a variable differential transformer and a controlled element. The sensor system includes a variable differential transformer with a housing encapsulating a first coil, a bore in the housing, wherein the bore is adjacent to the first coil, a core disposed in the bore, a shaft connectible between the core, at a first end, and the controlled element, at a second end, and a biasing element connected to the shaft. Responsive to a break in the shaft, the biasing element moves the core to an out-of-range position detectable by at least the first coil.

摘要： A helicopter autopilot system includes an inner loop for attitude hold for the flight of the helicopter including a given level of redundancy applied to the inner loop. An outer loop is configured for providing a navigation function with respect to the flight of the helicopter including a different level of redundancy than the inner loop. An actuator provides a braking force on a linkage that serves to stabilize the flight of the helicopter during a power failure. The actuator is electromechanical and receives electrical drive signals to provide automatic flight control of the helicopter without requiring a hydraulic assistance system in the helicopter. The autopilot can operate the helicopter in a failed mode of the hydraulic assistance system. A number of flight modes are described with associated sensor inputs including rate based and true attitude modes.

摘要： An injection jet (437) includes a body (601) having a first (701) and a second (703) passage disposed therein for channeling a fluid to a working element (303). The first passage (701) remains fluidly separated from the second passage (703). A system includes the injection jet (437) along with a main reservoir (405) and an emergency reservoir (415). The first passage (701) is in fluid communication with the main reservoir (405), while the second passage (703) is in fluid communication with the emergency reservoir (415). The system operates in a standard mode and an emergency mode. Both the first passage (701) and the second passage (703) are configured for jointly supplying fluid to the working element during standard mode. The second passage is configured for independently supplying fluid to the working element (303) during emergency mode.
