  • Patent number: 12151803
    Abstract: Presented are a method and apparatus for an aircraft flight surface actuation system including a motor having an output shaft. A gearbox is coupled with the output shaft, whereby a first driving force output via the motor is converted to a second driving force. A torque shaft assembly is driveably coupled with the gearbox. The torque shaft assembly includes a first tube, a second tube located at least partially through the first tube and located coaxial therewith, wherein the first tube comprises an axial preload operable to mitigate lateral deflection, and wherein the first tube comprises a torsional preload operable to mitigate torsional deflection. In addition, the aircraft flight surface actuation system includes an eccentric cam mechanism driveably coupled with the torque shaft assembly, and a flight surface coupled with the eccentric cam mechanism.

  • Patent number: 10066715
    Abstract: An electromechanical actuator (“EMA”) is provided with redundant load paths for driving the actuator stroke. The EMA includes a rotatable screw, a nut mated with the screw and having an external toothed surface, and a rotatable spline member having a splined surface engaging the external toothed surface of the nut. An actuator rod is coupled to the nut for linear movement with the nut. A first motor is operable to rotate the screw relative to the nut to cause the nut to travel linearly along the screw, and a second motor is operable to rotate the spline member and nut such that the nut travels linearly along the screw. Consequently, the actuator rod moves linearly by operation of the first motor alone, by operation of the second motor alone, and by simultaneous operation of the first and second motors. A no-back device may be incorporated into each load path.

  • Patent number: 6823679
    Abstract: A system to produce a densified fluid, and more particularly a densified propellant to be used in a launch vehicle. The system includes a vessel containing a first fluid and an injection nozzle to inject a cooling fluid into the vessel. The first fluid in the vessel has a freezing temperature greater than the boiling point of the second fluid that is injected into it. The second fluid is injected into the first fluid and evaporates therefrom to cool the first fluid. An anti-icing chamber is placed around the injection nozzle and a third fluid is provided to the anti-icing chamber to form an interface which does not allow the first fluid to contact the injection nozzle. In this way, the second fluid can be substantially continuously provided through the injection nozzle to the first fluid to cool the first fluid. A heat exchanger can then be provided in the vessel to cool an additional material.
