摘要： A method for evaluating a collective alignment of rotor blades for an aircraft while the aircraft is on the ground is disclosed. The method includes determining an air density altitude, and determining a torque value for each engine of the aircraft, while the aircraft rotor blades are operated at a normal speed and the rotor blades are set to a full down position for ground operations via a collective controller. The method further includes evaluating the collective condition by comparing the torque value to a predetermined flat pitch torque alignment limit for the air density altitude, and providing an indication of the collective condition.

摘要： Disclosed is a rotor track and balance system for rotorcraft that includes a data processing unit, a tachometer sensor and at least one accelerometer. The tachometer sensor is located remotely from the data processing unit and is mounted proximate to the rotating blades of the rotorcraft. The tachometer sensor is adapted to measure the speed and position of the rotating blades and to wirelessly transmit speed and position data to the data processor. The at least one accelerometer is also located remotely from the data processing unit and is mounted proximate the rotating blades of the rotorcraft. Each accelerometer is adapted to measure vibration anomalies in the rotating blades and to wirelessly transmit vibration data to the data processor. The data processing unit synchronizes the wireless data transmitted from the tachometer sensor and the wireless accelerometer(s) and determines necessary adjustments to be made in order to reduce the vibration anomalies in the rotor blades.

摘要： Synchronizing a wireless sensor includes receiving a first command at the wireless sensor, noting a first timestamp value indicating when the first reply is sent, responding to the first command with a first reply, receiving a second command at the wireless sensor that contains a second timestamp value indicating when the first reply was received and a third timestamp value indicating when the second command was sent to the wireless sensor, noting a fourth timestamp value indicating when the second command was received by the wireless sensor, and determining an offset at the wireless sensor using the first, second, third, and fourth timestamp values. The presence of the first timestamp value may be interpreted as a request to provide timestamp information for synchronization. An access point may communicate with the wireless sensor.

摘要： An actuation system having a configuration of first and second components, each component having longitudinally extending fingers interlaced with one another. Relative longitudinal movement is permitted between the fingers in a manner to permit the second component to be movable longitudinally with respect to the first component between a first position and a second position. A biasing member is provided within the configuration that biases the second component towards the second position. A wire is wound about the fingers that restrains the second component in the first position. A release device selectively causes the wire to be loosened about the fingers such that the biasing member moves the second component from the first position to the second position. An actuator connected to the second component moves with the second component from the first position to the second position.

摘要： A Reconfigurable Nose Control System (RNCS) is designed to adjust the flight path of spin-stabilized artillery projectiles. The RNCS uses the surface of a projectile nose cone as a trim tab. The nose cone may be despun by the action of aerodynamic surfaces, to zero spin relative to earth fixed coordinates using local air flow, and deflected by a simple rotary motion of a Divert Motor about the longitudinal axis of the projectile. A forward section of the nose cone having an ogive is mounted at an angle to the longitudinal axis of the projectile, forming an axial offset of an axis of the forward section with respect to the longitudinal axis of the projectile. Another section of the nose cone includes another motor, the Roll Generator Motor, that is rotationally decoupled from the forward section and rotates the deflected forward section so that its axis may be pointed in any direction within its range of motion. Accordingly, deflection and direction of the forward section may be modulated by combined action of the motors during flight of the projectile.
摘要翻译：可重构鼻子控制系统（RNCS）旨在调整旋转稳定炮弹的飞行路径。 RNCS使用弹丸鼻锥的表面作为装饰片。鼻锥可以通过空气动力学表面的作用去除，使用局部气流相对于地球固定坐标进行零旋转，并且通过转向马达围绕射弹纵轴的简单旋转运动而偏转。具有ogive的鼻锥体的前部部分以与射弹的纵向轴线成一定角度安装，形成相对于射弹的纵向轴线的前部分的轴线的轴向偏移。鼻锥的另一部分包括另一个电动机，即辊发生器电动机，其与前部旋转地解耦并使偏转的前部旋转，使得其轴线可以在其运动范围内的任何方向上指向。因此，前向部分的偏转和方向可以通过在抛射体飞行期间电机的组合作用来调节。
