Abstract:
Volume I presents the test program, correlations with other data, and discussions of the specific objectives of this investigation. In general it was shown that the small scale wind tunnel and water tunnel test techniques do provide reasonable dynamic force and moment data for a wide variety of planforms and conditions. The force testing of small-scale models in either a small wind tunnel or a water tunnel was investigated as an inexpensive and quick means to obtain meaningful dynamic force and moment data representative of rapidly maneuvering full-scale aircraft. Force tests of flat-plate semi-span models were conducted in the General Dynamics Aerodynamic Development Facility (ADF) which is a small 14x14 in low speed wind tunnel. Oscillatory model motions up to 48 deg (peak to peak) amplitude were tested at frequencies of 1 to 3 Hz. Force tests of flat and three-dimensional full span models were conducted in the General Dynamics Hydroflow Facility (HFF) which is a horizontal flow water tunnel with a 24x24 in. test section. Pitch/pulse model motions were tested for conditions similar to those tested in the ADF. Keywords: Aerodynamics, Unsteady flow, Vortex flow, Wind tunnel tests. (EDC)
