Abstract
-
The report documents the results of a study performed for the United States Air Force Flight Dynamics Laboratory to identify the high angle of attack post stall aerodynamic stability and control characteristics of the F-4 aircraft from existing full scale and radio-controlled drop model test data and to correlate these results with similar characteristics obtained from wind tunnel tests. A parameter identification procedure was set up to extract these nonlinear characteristics from flight test records using a nonlinear iterated Kalman filter/fixed-point smoother algorithm and a least square equation error method. Model form is established from wind tunnel data by representing the aerodynamic coefficients by Taylor's series expansions for selected ranges of angle of attack.
