Publisher's Synopsis
Measured and predicted pressure signatures from a lifting wind-tunnel model can be compared when the lift on the model is accurately known. The model's lift can be set by bending the support sting to a desired angle of attack. This method is simple in practice, but difficult to accurately apply. A second method is to build a normal force/pitching moment balance into the aft end of the sting, and use an angle-of-attack mechanism to set model attitude. In this report, a method for designing a sting/balance into the aft fuselage/sting of a sonic-boom model is described. A computer code is given, and a sample sting design is outlined to demonstrate the method.Mack, Robert J.Langley Research CenterFUSELAGES; SONIC BOOMS; WIND TUNNEL MODELS; SYSTEMS INTEGRATION; AERODYNAMIC BALANCE; PITCHING MOMENTS; ATTITUDE (INCLINATION); ANGLE OF ATTACK; COMPUTER PROGRAMS; LIFT...
