The vehicle configuration consists of blunt nose, variable sweep back wing and curved fore body. The Six component force and moment data were obtained over an angle of attack range from -15 to +15 degrees on the 1: 50 scale model in the wind tunnel. The sweep back angles are also changed for different test conditions. The experimental results are presented in terms of lift coefficients, Drag coefficients and L/D ratio for various angles of attack and different flow velocities. It is found that there is positive lift coefficient for the configuration at zero angle of attack with considerable drag reduction due to the variable sweepback wings and produces high L/D ratio.
