Book Description
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.

Book Description
An experiment was conducted to investigate the flow field around the port of secondary injection for thrust vector control through the use of a differential interferometer. Also, side forces were measured and compared with values calculated by a semi-theoretical method which was resulted from the flow field investigation, for various flow conditions. In parallel with the experimental study, numerical calculations of the flow field were made with Rusanov's method. The numerical results were in good agreement with the experimental data. A theoretical analysis of the unsteady flow about a solid cylinder falling through a viscous fluid contained in a vertical tube was performed so as to determine the locus of the falling cylinder under the influence of gravitational acceleration and to evaluate the time-dependent frictional resistance to the cylinder. The effort expended on research and analysis of a Thrust Producing Gyroscope has resulted in improving the understanding of the relationship among the factors involved in this device so as to determine the functional feasibility of the device in practice.
