Abstract : A tabulation is given of the 'Nonplanar Mach Box' results for unsteady generalized force coefficients for the planforms, Mach numbers, mode shapes, and frequencies recommended by AGARD. The tabulation uses the AGARD coordinate system and format. Not all the desired cases could be included because of the program's current limitation to supersonic trailing edges (leading edges can be supersonic or subsonic). The method was found to be fully workable and constitutes a valuable research and design tool. Convergence and accuracy were found to be comparable to steady-state, planar methods. The computer program is available with sample problems. (Author)
