Abstract:

This appendix volume contains the program listing and flowchart for the program described in Volume I and Volume II. The program is a numerical method that predicts the detailed pressure distribution on wing-body combinations at transonic Mach numbers less than one and integrates the pressures to obtain aircraft force and moment data. The code has been developed with the intent of providing the user with an easy to use and reliable tool. The basic inviscid prediction method is the modified transonic small disturbance theory program. In order to provide accurate surface pressure predictions on the wing, several additional features of the typical transonic flowfield have been incorporated. These consist of the viscous displacement effect, local strong viscous interaction at the shock wave foot and at the trailing edge including an approximate treatment of local shallow separations, and finally, the interaction effect of the fuselage.
