Small Scale Model Tests in Small Wind and Water Tunnels at High Incidence and Pitch Rates. Volume 3. Water Tunnel (HFF) Data Base

Abstract

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 sq 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. Forces 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 sq in. test section. Keywords: Aerodynamics; Unsteady flows; Vortex flows; Wind tunnel testing; Water tunnel testing.
