A device for indicating the Mach number of a supersonic aircraft comprising an element carried by the craft and exposed to the free supersonic air stream, said element creating a shock wave during supersonic flight, the angle of the wave varying with These details and drawings of patents granted in the United States are taken, by permission of the changes in the Mach number of flight, means sensing Department of Commerce, from the 'Official Gazette of the United States Patent Office'.
