ABSTRACT:
A flight vehicle comprises a vehicle body with a duct having a longitudinal axis extending through the body, and a fan for inducing a flow of ambient air through the duct from an inlet end to an outlet end to provide a thrust acting along the axis of the duct. A system of control is provided for varying the attitude of the vehicle without re-directing or substantially re-directing the thrust whereby the vehicle is capable of controlled flight from a take-off mode in which the axis of the duct is vertical or substantially vertical, to a forward flight mode in which the axis of the duct is inclined to the vertical. A pair of wings are provided on the outer surface of the body, the wings being on opposite sides of the body and having no or substantially no dihedral.
