A FLOW MODEL AND ANALYSIS OF A ROCKET PAIR IN CLOSE PROXIMITY

Abstract

In the flight of a pair of rockets or the salvo firing of several rockets, the trailing ones may be deflected toward the trajectory of the leading rocket. The progress that has been made in investigating the aerodynamic aspects of this problem are presented in this report. Two areas in the flow field have been isolated as regions in which an aerodynamic interaction could occur between rockets. A mathematical model has been developed which simulates the simpler of these regions: the perturbation of an inviscid, incompressible flow field by the passage of the leading rocket and the subsequent flight through this disturbed flow by the trailing rocket. This model employs a numerical method known as the method of successive overrelaxations to compute the resultant of the aerodynamic pressure force and the point at which it is concentrated for both a leading and a trailing rocket. The data that are required by the model and the problem areas that remain in the preparation of these data are presented and discussed.
