Stalling characteristics of a general aviation aircraft

Analytical and numerical estimates of the stalling characteristics of a small, single-engine aircraft are compared with flight test results. Analyses include nonlinear simulation and linear stability-and-control evaluation, using aerodynamic and thrust characteristics obtained from a full-scale test in the NASA Langley Research Center 30 X 60-ft Wind Tunnel as well as subscaie model test data. Flight tests include prestall calibration runs, symmetric gradual stalls, and mildly accelerated stalls in the vertical plane. These tests tend to confirm predictions based upon wind-tunnel results, and they indicate areas in which special care must be taken in collecting data for aerodynamic parameter identification.
