Abstract:

This report presents the general, free-flight data on 2.75-inch FFAR pair firings at large yaw angles of approximately 80 to 100 degrees. The rockets consistently recovered from the extreme launch angles. Their 50 circular probable error dispersion was 29.3 mils. Free-flight time and position data were obtained from film, using a network of high-speed cameras. The free-flight position of the test rockets and the position of the SUU-20A launcher mounted on top of the moving track sled were determined from motion picture film data by triangulation methods referenced to surveyed target poles in the background. This report is comprised of original test data and some analysis and conclusions on free-flight stability and dispersion. Author
