Analysis of Transient Flow in the Case of Secondary Injection for Transient Vector Control (RESEARCH NOTE)
The purpose of this paper is to analyze the flow field structure in transient state and performance of secondary injection system for thrust vectoring in divergent section of a two-dimensional nozzle. Secondary injection for thrust vectoring in a two-dimensional nozzle is studied by solving three-dimensional Reynolds-averaged equations by means of fluent solver. Spalart-allmaras model was used ...
متن کاملSecondary Production of Massive Quarks in Thrust
We present a factorization framework that takes into account the production of heavy quarks through gluon splitting in the thrust distribution for e+e−→ hadrons. The explicit factorization theorems and some numerical results are displayed in the dijet region where the kinematic scales are widely separated, which can be extended systematically to the whole spectrum. We account for the necessary ...
متن کاملeffects of divergence angle on moveable nozzle performance in thrust vector control system
in this paper, by numerical simulation of gas flow, effects of divergence angles on the amplification factor, side force and thrust vector magnitude of a moveable nozzle with supersonic split line have been investigated. the study is conducted for constant exit to throat area ratio and the location of the split line is also constant. the finite volume method with second order upwind scheme for ...
متن کاملThrust Vector Control of an Upper-Stage Rocket with Multiple Propellant Slosh Modes
The thrust vector control problem for an upper-stage rocket with propellant slosh dynamics is considered. The control inputs are defined by the gimbal deflection angle of a main engine and a pitchingmoment about the center of mass of the spacecraft. The rocket acceleration due to themain engine thrust is assumed to be large enough so that surface tension forces do not significantly affect the p...
