Analysis and Comparison of Aerodynamic Data Obtained in a Large Wind Tunnel and a Moving-Model/Track Facility for a General Research Tilt-Wing/ Propeller VTOL Configuration
Abstract
A comparison and analysis was conducted of the aerodynamic characteristic data obtained in a large wind tunnel and a moving-model/track facility for a general research tilt-wing/propeller VTOL configuration. The experiments included test conditions corresponding to free-stream velocities from transition flight to hovering and wing angles of attack up to 90 degrees. The experimental data obtained from both facilities are compared in several ways in a series of graphs plotted in coefficient form for the range of slipstream thrust coefficients of 0.80 to 0.95. The comparisons and analyses first are made on the basis of wind-axes force and moment coefficients and drag polars. An additional comparison is made of the wing forces by using body-axes force coefficients and polars.
