Title: Position lights for supersonic aircraft - has light source producing beam of parallel light rays and refraction system
IPC: F21S8/10
Filed: 1973-06-15
Abstract: This invention relates to a light contained within the constricted confines of the narrow wing of a supersonic aircraft, avoiding any protrusion which might cause turbulence prejudicial to the aerodynamic qualities of the aircraft. The light is located in the point of the leading edge of the wing.
