Lateral Spread of Sonic Boom Measurements from U.S. Air Force Boomfile Flight Tests
Abstract
A series of sonic boom flight tests were conducted by the US Air Force at Edwards AFB in 1987 with current supersonic DoD aircraft. These tests involved 43 flights by various aircraft at different Mach number and altitude combinations. This paper compares the measured peak overpressures to predicted values as a function of lateral distance. Some of the flights are combined into five groups because of the varying profiles and the limited number of sonic booms obtained during this study. The peak overpressures and the lateral distances are normalized with respect to the Carlson method predicted centerline overpressures and lateral cutoff distances, respectively, to facilitate comparisons between sonic boom data from similar flight profiles. This paper demonstrates that the data obtained in this study agrees with sonic boom theory and previous studies and adds to the existing sonic boom database by including sonic boom signatures, tracking, and weather data in a digital format.
