Landing Support Assembly For Aerial Vehicles

A landing support assembly to at least partially support an aerial vehicle on a surface may include a strut extendable to a deployed state and retractable to a stowed state during flight. The strut may be configured to pivot with respect to a bracket coupled to the aerial vehicle between the deployed state and the stowed state. The landing support assembly further may include a strut actuator coupled to the strut via a linkage to cause the strut to pivot relative to the bracket. The landing support assembly also may include a foot coupled to an end of the strut remote from the bracket. The foot may be configured to change between a retracted state during flight having a first cross-sectional area and an at least partially splayed state for at least partially supporting the aerial vehicle and having a second cross-sectional area greater than the first cross-sectional area.

Method and apparatus for remote angle calibration and measurement

Methods and devices to measure an angular deflection of an aircraft member. The devices are configured to be attached to the aircraft member. The devices are configured to obtain an orientation of the device about three separate axes. The methods use initial orientation values and dynamic orientation values to calculate an axis of rotation. Using the axis of rotation, the deflection angle can be calculated for the aircraft member.

Method of moving an aircraft undercarriage between a deployed position and a retracted position

The invention provides a method of moving an aircraft undercarriage comprising a leg (1) that is movable between a deployed position and a retracted position in which the leg is held stationary by means of a strut (2) held in an aligned position by a stabilizer member (4), the method including using a drive actuator (10) for raising the undercarriage from the deployed position to the retracted position. According to the invention, the actuator is coupled firstly to the leg and secondly to the stabilizer member in such a manner that on being activated the actuator begins by causing the stabilizer member to unlock and then moves the undercarriage leg towards the retracted position.
