Title
(EN) Craft having aerofoil surface for controlling its spin
Abstract
(EN)
To prevent the spin of a craft designed to move though, or on a surface of a fluid, means are provided to vary the effective surface area of an aerofoil 6. The craft may be of the type in which a fan 2 directs fluid over a dome-shaped canopy 1 utilising the Coanda effect to generate lift, a plurality of aerofoils 6 being used to counter unwanted rotation of the canopy caused by a reaction to the rotation of the fan. Each aerofoil 6 may be driven into or out of a respective slot by means of an actuator controlled by a signal generated in response to comparison of an output signal, produced by an optical or piezoelectric gyroscope, with a desired attitude set by a steering mechanism. The aerofoils 6 may be located where the angle of attack in relation to the airfiows 7, 14 produced by the fan 2 is significantly dependent upon fan speed.
