摘要:
A gas turbine engine includes a fan duct, an inner fixed structure, and a thrust reverser assembly. The inner fixed structure forms an inner diameter of the fan duct and encloses a core compartment. The thrust reverser assembly includes a linkage assembly mounted to the inner fixed structure within the fan duct. The linkage assembly is adapted to act as a ventilation system that allows for communication between the fan duct and the core compartment.
摘要:
A method of thrust reversal operation according to an example of the present disclosure includes, among other things, permitting an increase in engine power when at least one criterion is not met and a thrust reverser is deployed, and denying the increase in engine power when the at least one criterion is met. A system for thrust reversal is also disclosed.
摘要:
The present invention relates to a thrust-reversal device for an aircraft which includes at least two thrust reversers including a cowl which is movable between a closed position and an open position, actuated by at least one actuator (5, 5') driven by at least one electric motor powered by a single power-conversion module (100, 200, 300) supplied with electricity by a single electricity source of said aircraft. The device according to the invention is characterised in that the power-conversion module includes at least one autotransformer (301) supplied with AC electric voltage by the electricity source (3) and connected to at least one rectifier stage suitable for converting said AC voltage into DC voltage, said rectifier stage being connected to a stage for balancing and/or smoothing the current which is suitable for supplying DC voltage to said electric motor (6, 6') of said actuator (5, 5') of said cowl.
摘要:
A blocker door for a gas turbine engine thrust reverser having a tray with a base and sidewalls extending about the base to define a volume, the volume being closed by a cover that extends beyond the periphery of the tray. The extension of the cover beyond the periphery provides a sealing feature.

This system for actuating at least one aircraft nacelle element comprises at least two actuators (A1, A2, A3) kinematically linked together, a main hydraulic (or electric) generation circuit (1) able to operate at least one (A1) of the two actuators, and a secondary electric (or hydraulic) generation circuit (13) able to operate the other actuator (A3).
摘要:
The invention relates to a system for actuating a plurality of actuators (15) that can move a mobile panel of an aircraft nacelle. Said system comprises at least two motors (16) that can drive the actuators (15), the two motors (16) being controlled and supplied by at least two separate control units (33, 35), and the actuators (15) being mechanically interconnected by a mechanical transmission (37). The invention also relates to a nacelle comprising such an actuating system.
摘要:
A thrust reverser system that includes one or more power drive units (220) operable to supply a drive force. The power drive unit includes a motor (214) and at least two output sections (216a, 216b), each operably coupled to transmit the drive force to the trust reverser movable components. Each of the output sections is operable to decouple the motor (214) from associated trust reverser movable components upon a torque magnitude being reached in the output section. A deadband coupler (302) is provided to couple the first and second output sections together a time period after the torque magnitude is reached in one of the output sections.
