摘要： A ram air turbine (RAT) restow system includes an actuator assembly with a piston interposed between an upper fluid compartment and a lower fluid compartment. The actuator assembly is configured to selectively move the piston between a deployed position and a stowed position. A hydraulic restow circuit is interposed between the actuator assembly and a hydraulic fluid system that is configured to output fluid. The hydraulic restow circuit includes a restow valve configured to operate in a first position that establishes a first fluid path to deliver the fluid to the upper fluid compartment and a second position that establishes a second fluid path to deliver the fluid to the lower fluid compartment.

摘要： A containment structure for a rotor includes a shroud and a shroud reinforcement. The shroud is coaxial with and partially surrounds the rotor and includes a tubular section, a transition section, and a flange section. The tubular section extends axially past a first side of the rotor. The transition section connects to the tubular section and is adjacent to a curved side of the rotor. The flange section connects to the transition section opposite the tubular section. The flange section extends radially past a radially outer side of the rotor. The shroud reinforcement is connected to a radially outer surface of the transition section. The shroud reinforcement encloses the transition section and includes a support scaffold and a reinforcing material. The support scaffold includes a series of geometric retaining features encircling a radially outer surface of the transition section. The reinforcing material couples to the support scaffold and restricts shroud radial expansion.

摘要： A ram air turbine control valve includes a sleeve, a spool, and a return housing. The sleeve defines a first exit port disposed proximate a first end of the sleeve and defines a second exit port disposed between the first exit port and the first end. The spool is radially contained within the sleeve and is movable between a first position and a second position. The return housing is coupled to the first end of the sleeve and defines a cavity that receives a biasing member that engages the spool.

摘要： A ram air turbine assembly includes a governor shaft rotatable about an axis and a stop shaft coupled for rotation with the governor shaft. A rotatable housing portion surrounds at least a portion of the stop shaft. A lock plunger extends through an opening in the rotatable housing portion to prevent rotation of the rotatable housing portion and minimize vibration impact loading when stowed.

摘要： The present subject matter overcomes the deficiencies in the prior art by introducing or generating charged particles in an air stream and manipulating the air stream with magnetic fields operating on the charged particles. Embodiments of the present subject mater compress the air stream by accelerating charged particles with a moving magnetic field, where the magnetic field has a velocity perpendicular to its flux lines. The increased velocity of the charged particles increases the statistical mean particle velocity and thereby increases the pressure in the air stream. The compressed air stream is then heated and expanded through a second magnetic field. The expansion of the air stream substantially increases the velocity of the air stream and the charged particles therein. The interaction of the high velocity charged particles and the magnetic field imparts a force perpendicular to the flux lines, this force powers the movement of the magnetic field.
摘要翻译：本发明通过在空气流中引入或产生带电粒子并利用在带电粒子上运行的磁场来操纵空气流来克服现有技术中的缺陷。本发明的实施例通过用移动磁场加速带电粒子来压缩空气流，其中磁场具有垂直于其通量线的速度。带电粒子的增加的速度增加统计平均粒子速度，从而增加空气流中的压力。然后将压缩空气流通过第二磁场加热和膨胀。空气流的膨胀大大增加了空气流和其中的带电粒子的速度。高速带电粒子与磁场的相互作用赋予垂直于磁通线的力，该力为磁场的运动提供动力。
