  • Device for determining the rotation angle of a shaft in an aircraft
    Patent number: 7644634
    Abstract: A device for determining the rotation angle of a shaft in an aircraft, the device having a shaft and a motor operable to rotate the shaft to operate a component and to detect first rotation data of the shaft. The device also includes a position pickup unit designed to detect second rotation data of the shaft, and a synchronization unit for synchronizing the first rotation data with the second rotation data.
    Type: Grant

  • Device for determining the rotation angle of a shaft in an aircraft
    Patent number: 7437955
    Abstract: Nowadays position pickup units are commonly used in order to measure the rotation position of a shaft for operating a landing flap or landing slat or a brake flap in an aircraft. In the case of failure of such a position pickup unit (PPU) the corresponding drive motor of the shaft has to be switched off because position data is no longer present. According to one embodiment of the present invention a device for determining the rotation angle of a shaft in an aircraft is stated, with said device comprising a shaft and a motor, wherein rotation of the shaft is measured by way of the motor. This measuring data can be evaluated together with the data of the PPU. In this way improved system availability is ensured.
