LIFT ENHANCEMENT ASSEMBLY OF AN AERIAL VEHICLE WITH FIXED WINGS
Present invention relates to a lift assembly (300) in an aerial vehicle. The lift assembly (300) comprises a wing (102) and at least a vertical rotor (118) disposed below the wing (102). A vertical axis (121) of the vertical rotor (118) is positioned within a wing span of the wing (102). The vertical rotor (118) is operational during forward flight of the aerial vehicle. A placement distance (122) between the leading edge (108) and the vertical axis (121) of the vertical rotor (118) is a factor of RPM of the rotor (118), angle of attack (116) of the wing, and a wing chord (117). The lift assembly (300) produces enhanced lift higher than the sum of lift produced by the wing (102) and the rotor (118) individually, which enables the provision of small wings and hence incur reduced drag.
AIRCRAFT WING CONTROL
A vehicle comprising a morphing wing and a body is disclosed. The aircraft is configured to transform from a first configuration into a second configuration for ascent or descent of the aircraft. The drag force and lift force on the aircraft in the second configuration are less than in the first configuration. Transforming from the first to the second configuration comprises: contracting the wing within a geometric plane defined by the wing, and rotating the outer edge of the wing downwards, out of the geometric plane.

Actuator assembly for moving an aircraft wing tip device
An actuator assembly for moving an aircraft wing tip device is disclosed. The wing tip device is rotatable about a hinge axis relative to a fixed wing of the aircraft. The hinge axis is orientated non-parallel to a line-of-flight direction of the aircraft. The actuator assembly includes a primary shaft having an axis of rotation orientated substantially parallel to the line-of-flight direction, a motor to cause rotation of the primary shaft, and a secondary shaft orientated substantially parallel to the hinge axis. The secondary shaft is couplable to the primary shaft and is arranged to rotate the wing tip device in response to the rotation of the primary shaft.
