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.

摘要： An aircraft flight surface control system and method simultaneously provides the benefits of both an active/active system architecture and an active/standby system architecture. The system is preferably implemented using hydraulic actuator assemblies (202H,204H,206H) and electromechanical actuator assemblies (202E,204E,206E) coupled to the same flight control surface. During normal system operations the electromechanical actuator assemblies are energized to supply a relatively minimal force to associated flight control surfaces. In effect, the electromechanical actuators, although energized, may be pulled along by the associated hydraulic actuator assemblies, until needed. Thus, the electromechanical actuator assemblies are controlled in a manner that closely resembles the active/standby architecture.

摘要： A hydraulic actuator is configured to provide redundant boost control to an aircraft within approximately the same space required by a single hydraulic cylinder. The hydraulic actuator includes a housing and a piston assembly disposed within the housing. The piston assembly includes a ram, a first piston secured to the ram, and second and third pistons disposed on the ram such that the second and third pistons are translatable relative to the longitudinal axis pf the ram. The pistons form two hydraulically separate actuator cylinders within the space required by a single cylinder which results in a reduction in the weight and size of the hydraulic actuator.

摘要： Two or more flow control valves (140a, 140b) may be used to provide redundant flow control for a hydraulic actuator (111) or servoactuator. The flow control valves include a sleeve (142a, 142b) control spool (146a, 146b). Under normal operating conditions, each bypass control spool is stationary relative to the sleeve and the flow control valve functions as a four-way hydraulic flow control valve. Each flow control valve is connected to a bypass-shutoff valve (160a, 160b) including a bypass spool that is moveable from a shut-off position to a bypass position. Upon supply pressure failure to one flow control valve, the bypass spool moves to the bypass position, reducing pressure in the corresponding actuator piston chambers. When a primary control spool (146a, 146b) becomes jammed, the corresponding bypass control spool moves within its sleeve (142a, 142b) allowing a bypass groove to port control pressure to the return line, thereby reducing pressure in the corresponding actuator piston chambers.

摘要： An aircraft flight control surface actuation system (110) includes a plurality of flap actuators (112), and a plurality of slat actuators (114). The actuators receive actuator position commands from an actuator control unit (124) and, in response, move flaps (102) and slats (104) between stowed and deployed positions. The flight control surface actuator control unit (124) includes a plurality of independent actuator control channels. One or more of the independent actuator control channels (126-1, 126-2, 126-3, 126-4, 126-5) is coupled to both a flap actuator (112) and a slat actuator (114), and is configured to selectively supply the actuator position commands thereto.

摘要： A backup system is provided that has a local electric motor (42) and pump (41) for some or all of the hydraulic actuators on an aircraft. A local backup hydraulic actuator (27) has two power sources, hydraulic as primary and electrical as backup. During normal operation, the hydraulic actuator receives pressurized fluid from a hydraulic system (45) and the fluid flow to the chambers is controlled by a servo valve (44). If the hydraulic system fails, the electronic controller (55) detects the failure by observing the signal indicative of the pressure from the pressure sensor (48), and the controller powers the local hydraulic pump (41) to provide high pressure hydraulic fluid to the hydraulic actuator via the servo valve (44).
