Abstract : A study was made to develop an analytical method for determining the loads caused by the exhaust gases of a rocket motor impinging on a launcher. One of the requirements of the study was that the method developed be for a general case (i.e., not a specific missile, motor, or launcher). Therefore, methods had to be developed for determining the trajectory, jet exhaust flow field, and calculation of forces and moments on an arbitrary structure. Contained in this report is the formulation of this analytical method. An additional requirement of this study was to develop a digital computer program which, with a minimum amount of input data, can compute the forces and moments on a given structure and missile configuration. A description of this program (BLAST) and an input guide is contained in the Appendix. (Author)
