摘要： A electric taxi system (ETS) for an aircraft may comprise drive units mounted coaxially with wheels of the aircraft and dedicated motor control units for the drive units. The motor control units may be operable independently of one another so that a first one of the drive units can be operated at a speed different from an operating speed of a second one of the drive units. Independent operability of the drive units may provide enhanced maneuverability of the aircraft during taxiing.

摘要： An electric taxi system (ETS) for an aircraft may comprise drive motors mounted coaxially with wheels of the aircraft. A clutch assembly may be interposed between the drive motor the wheel. The clutch assembly may transmit torque from the motor to the wheel when the wheel and a rotor of the motor rotate at the same rotational speed. The clutch assembly may self-disengage a rotor of the motor from the wheel when the wheel rotates faster than the rotor.

摘要： An actuator that at least inhibits the deleterious effects of corrosive fluids, such as salt-laden air, does not rely on relatively expensive materials. At least a portion of the actuator housing is sealed from the surrounding salt-laden air, and is in fluid communication with an air reservoir that includes a supply of relatively salt-free, or substantially salt-free, air. The actuator is configured to exchange air between the air reservoir and the actuator housing, thereby at least substantially inhibiting the ingress of salt-laden air into much of the actuator.

摘要： A thrust reverser system includes one or more actuators each having a locking mechanism that prevents unintended actuator movement, and thus unintended thrust reverser movement. Each of the actuators additionally includes a lock inhibitor assembly that engages the lock and prevents it from moving to its locked position until the actuator is moved into a stow position. Upon movement to the stow position, the lock inhibitor assembly disengages the lock, and the lock automatically moves into its locked position.

摘要： An aircraft taxi drive system includes a motor that is configured to transfer power to an aircraft wheel via a drive chain, such that the motor rotates the aircraft wheel via the drive chain. In some examples, the drive chain is movable between first and second positions. In the first position, the drive chain, such as an exterior surface of the drive chain, is engaged with a driven sprocket that is mechanically connected to an aircraft wheel. In the second position, the drive chain is disengaged from the driven sprocket.

摘要： Systems and methods of controlling solid propellant burn rate, propellant gas pressure, propellant gas pressure pulse shape, and propellant gas flow rate, rely on pulse width modulation of a control valve duty cycle. A control valve that is movable between a closed position and a full-open position is disposed downstream of, and in fluid communication with, a solid propellant gas generator. The solid propellant in the solid propellant gas generator is ignited, to thereby generate propellant gas. The control valve is moved between the closed position and the full-open position at an operating frequency and with a valve duty cycle. The valve duty cycle is the ratio of a time the control valve is in the full-open position to a time it takes the valve to complete one movement cycle at the operating frequency. The valve duty cycle is controlled to attain a desired solid propellant burn rate, propellant gas pressure, propellant gas pressure pulse shape, and/or propellant gas flow rate.

摘要： A drive shaft is configured to be disposed between a drive mechanism and a plurality of driven mechanisms and to transfer a drive torque generated by the drive mechanism to one of the plurality of driven mechanisms. The drive shaft includes a first shaft section and a second shaft section. The first shaft section has a first outer diameter, and is dimensioned to be disposed within the drive mechanism, within one of the plurality of driven mechanisms, or simultaneously within the drive mechanism and one of the plurality of driven mechanisms. The first shaft section is also configured to at least selectively engage, and thereby at least selectively receive the drive torque generated in, the drive mechanism. The second shaft section is coupled to the first shaft section and has a second outer diameter that is less than the first outer diameter. The second shaft section is dimensioned to be disposed within either the drive mechanism or one of the plurality of driven mechanisms.
