An analysis was made of flight test data to obtain information representing the atmospheric turbulence inputs to the test aircraft. The basis of the method was the use of the line arized equations of motion of the aircraft, with the addition of certain terms representing the aerodynamic effects of the turbulence on the aircraft. These equations were set up on an analog computer and verified by the technique of matching transient response flight data. Then, through the use of a feedback system, the desired turbulence quantities were obtained as system outputs. Inputs to the system were the aircraft response and control deflections, obtained from the flight test data. The method was found to be valid, assuming the aircraft analogue was correct. The resulting data appeared suitable for further analysis to determine its statistical qualities.
