Abstract:

An investigation of the low-subsonic flight characteristics of a model having a thick flat 75 degrees swept delta wing with a half-cone fuselage on the upper surface was made in the Langley full-scale tunnel over an angle-ofattack range from about 20 to 40 degrees. Static and dynamic force test data were also obtained. The longitudinal flight characteristics were generally satisfactory over the angle-of-attack range of the investigation. Because of low damping of the Dutch roll oscillation, the lateral stability and control characteristics were poor throughout the angle-of-attack range 20 to 30 degrees where flights were possible without artificial damping. Artificial damping in roll greatly improved the lateral characteristics so that flights could be made up to an angle of attack of about 40 degrees. Author
