A numerical and experimental investigation of the thrust vector control by secondary gas injection
Abstract
A numerical and experimental analysis of the cross injection of secondary gas stream into a supersonic flow is presented. The two dimensional compressible Navier-Stokes equations were solved by the explicit Runge-Kutta finite volume method. The equations describing the turbulent flow are closed by an algebraic turbulence model. The results of the numerical calculations are compared with experimental results performed in a rectangular expansion nozzle with a two dimensional injector. Shadow graphs, wall pressure, and side thrust measurements were used as diagnostic tools. A parametric study concerning the influence of different injection conditions and gas media delivers the best injection conditions for a maximal side thust. The effect of the different jet injection conditions is discussed in connection with the corresponding flow structure.
