Abstract:
Disclosed is a method of control and stabilisation of aircraft. In one aspect pitch and roll may be controlled by a simple method of signalling to or from a reference location in a number of different ways. Both height and lateral position may be controlled. In a further aspect, polarised light may be used to determine the relative rotation of the aircraft. Additionally, preferred aircraft and associated features are disclosed.
Abstract:
A method and apparatus for controlling a powered craft in flight by an unsupported hand held control element. The position and attitude of the craft are controlled by the position and attitude of the control element. The position and attitude of the craft is determined with respect to a straight line between the controller and the craft, for example a beam of radiation. The controller and the craft are both provided with transducers comprising emitter and/or detector arrays in communication with one another.
