ASSESSING THE SONIC BOOM OF A FULL-SIZE AIRCRAFT FROM FREE FLIGHT TESTS ON A SUB-SCALE MODEL

Since the cost of conducting flight tests is proportional to the size and weight of the aircraft, the use of sub-scale models to characterize the sonic boom of the full-scale aircraft is a more desirable option. For this purpose, considerable effort has been devoted to defining a hybrid scaling concept for the sonic boom, combining Whitham's theory, free-flight tests, and a propagation model.
