E-954 This NACA High-Speed Flight Research Station photograph of the XF-92A was taken at the South Base of Edwards Air Force Base. The photograph is a top view of the aircraft's right side and provides a good view of the fuselage and delta wings. The Convair XF-92A aircraft was powered by a Allison J33-A turbojet engine with an afterburner, and was unique in having America's first delta wing. The delta wing's large area, thin airfoil cross section, low weight, and structural strength made this design a promising combination for a supersonic airplane. 1953 NASA Photo / NACA/NASA XF-92A Project Description
