This invention relates to air-craft and particularly to means for reducing the velocity thereof when occasion arises. In the operation of air-craft, it is frequently desirable to quickly reduce the velocity of the craft, as in preparation for landing or to avoid collision with some unexpected obstacle. In the operation of rocket planes designed for high altitude work, very great speed will be attained beyond the earth’s atmosphere and upon the return of the plan to a denser atmospheric medium, reduction in speed must be quickly accomplished to permit the plane to be landed without destructive results. It is the general object of my invention to provide simple means for reducing the velocity of an air-craft without causing the plane to diverge from its line of flight and without taking the plane out of control of the operator. It is a further object of my invention to accomplish the above defined purpose without substantially adding to the weight of the air-craft or increasing the air resistance of the craft when the decelerating device is not in use.
