    摘要： A system and method for blade angle position feedback. The system comprises an annular member operatively connected to rotate with a propeller, a sensor fixedly mounted adjacent the annular member and configured for detecting a passage of each singularity as the annular member is rotated and axially displaced and for generating a sensor signal accordingly, the annular member and sensor configured for relative axial displacement between a first relative axial position and a second relative axial position respectively corresponding to the first and the second mode of operation, and a detection unit connected to the sensor for receiving the sensor signal therefrom, determining on the basis of the sensor signal a time interval elapsed between the passage of successive singularities, and computing from the time interval blade angle position.

    摘要： This invention relates to a blade assembly comprising: a hub which is rotatable about an axis; at least one blade (316) having an aerofoil portion and a root (318), wherein the root is coupled to the hub using a primary retention device (322) which prevents radial separation of the root and hub in normal use; and, a secondary retention device which comprises an annular catcher (336) having a restriction (338) through which the root portion cannot radially pass, the restriction being located radially outwardly and radially spaced from the root part during use.

    摘要： The invention relates to a device for attaching a blade that includes a ferrule (28) mounted about an outer collar (23) of the pivot (15) of the blade (27), and capable of rotating by a sufficient angle so that cleats (30, 31) can close the ends of the pivot notch and maintain therein the base of the blade (27), as well as mobile wedges that facilitate the maintaining of the base in place within the notch. The invention can be used in aircraft machines.

    摘要： An aircraft seat has an adjustable armrest in which the armrest platform (42) is supported by a hinged attachment (46) to an armrest support member (38). The hinged attachment between the armrest platform and the arm support member is located at the wrist-end of the arm support member near the aircraft control stick. The armrest platform and the armrest support are locked into position by means of telescoping struts (62,54) that are controlled at the wrist-end of the arm platform member. The telescoping struts can be selectively locked to create triangular and/or quadrilateral trusses that lock the armrest firmly into position and may include springs or other elements to bias the armrest platform up and forward so that the armrest "floats" when the telescoping struts are released.
