摘要： A method for controlling a propeller of an aircraft, comprises receiving, with a processor, one or more signals indicative of commanded collective pitch of the propeller; receiving, with the processor, one or more sensed signals indicative of propeller axial speed, propeller rotational speed, and air density; estimating, with the processor, a propeller torque and propeller thrust from one or more of the propeller axial speed, the propeller rotational speed, and the air density; determining, with the processor, information indicative of an error value between a desired torque and a measured torque in the propeller; determining, with the processor, information indicative of a corrected pitch command in response to the determining of the error value; combining, with the processor, the corrected pitch command with the propeller rotational speed into an adjustment solution; providing, with the processor, the propeller with the adjustment solution.

摘要： A bond fixture includes a first fixture having a heater and a plurality of clamps. Each of the plurality of clamps includes a first member and a second member rotatable between a first position and a second position. A second fixture includes a root end lift translatable vertically between a retracted position and an extended position and a root end clamp translatable along a horizontal axis. The root end clamp is configured to cooperate with the root end.

摘要： A system and method for identifying a slung load for an aircraft with one or more sensors includes receiving, with a processor via one or more sensors, sensor information related to flight dynamics data for the aircraft; determining, with the processor, control input commands for the aircraft in response to the receiving of the flight dynamics data; determining, with the processor, signals indicative of an estimated pendulum frequency; and determining, with the processor, parameters associated with the slung load in response to the determining of the estimated pendulum frequencies.

摘要： An inertia reel mount for a seat includes a slide, a carriage arranged to support a seatbelt inertia reel, and a damper. The carriage is movable between first and second positions relative to the slide. The damper is fixed to the slide, is arranged between the carriage and the slide to oppose movement of the carriage, and is arranged to absorb kinetic energy from the carriage from sudden acceleration of a seat occupant secured in the seat by the seatbelt as the carriage moves from the first position to the second position.

摘要： An aspect includes space partitioning for vehicle motion planning. A plurality of obstacle data is analyzed to determine a plurality of obstacle locations in a configuration space of a vehicle. A partitioning of the configuration space is performed to compute a skeletal partition representing a plurality of obstacle boundaries based on the obstacle locations. The skeletal partition is used to preferentially place a plurality of samples by a sampling-based motion planner. At least one obstacle-free path is output by the sampling-based motion planner based on the samples.

摘要： A computer system and method is provided to filter clearance sensor data output by a sensor system during a load/offload procedure of a first object relative to a second object. A processing device of the computer system is configured to access hard threshold data, unique threshold data, and sensor data output by the sensor system sensing aspects of the load/offload procedure. The processing device is further configured to determine whether the sensor data exceeds the unique threshold, determine whether the sensor data that is determined to exceed the unique threshold is voidable data related to a non-critical event, and generate filtered sensor data that includes modifications to the voidable data.

摘要： An aircraft includes an airframe and a rotary component rotatably connected to the airframe by way of a plain bearing. The rotary component is part of a rotorcraft control system. The plain bearing includes an inner member rotatably engaged in at least two axes of rotation to an outer member. The inner member has a coefficient of thermal expansion (CTE) substantially less than that of the outer member.

摘要： The disclosure herein relates to power leveling mechanisms comprising a high frequency controller. The power leveling mechanism receives a power demand signal indicating a power requirement of a vehicle and determines a high frequency component of the power demand signal. The power leveling mechanism also provides a signal to a primary propulsion system and provides, via the high frequency controller, a high bandwidth signal based on the high frequency component to an auxiliary propulsion system.
