Research and Analysis in the General Area of Fluidic Control Systems.

Abstract

The secondary injection is a method of thrust vector control for the missile flight. In this method, a fluid is injected into the rocket expansion nozzle, causing an aerodynamic obstruction in the main stream of the nozzle. This obstruction then produces a shock wave and a boundary layer separation accompanied by a positive pressure region on the wall near the injection port, resulting in a side force amplification for the thrust vector control. The objective of this study is to compare the two types of secondary injections in the aspects of performance in terms of effectiveness and efficiency, and of system weight so as to provide a first step in the approach to the solution of the problem.
