Abstract
This report concerns an experimental investigation of the winglet integration, rudder deflection and aileron-rudder interaction effects on the Flying V aircraft configuration using a 4.6% scale model. The effects on the lift, drag, side-force, rolling moment, pitching moment and yawing moment coefficients are all described. The first results compare and contrast those for the model with the winglet installed to those without. Next, the effects of the rudder on the aerodynamic coefficients are presented along with the rudder control derivatives. Then, the effect of the third control surface (aileron) on the aerodynamic coefficients and rudder control derivatives are found. Finally, effect of changing the airspeed on the rudder control derivatives are presented.
