تحلیل چیدمان انژکتورها و توزیع دبی پاشش در سامانه کنترل بردار تراست به روش پاشش مایع(علمی-پژوهشی)
Authors
Abstract:
In this paper, the effect of secondary fluid injection on deviation and control of thrust vector with use of sprayed liquid fluid multi injection in to divergence nozzle flow is studied. Freon fluid as injection fluid have been chosen that more applicable and the fluent software is used for simulation flow field. In this investigation after grid study, different simulations in order to obtain the effect of injection flow rate, quality of distribution of injection rate between injectors, number of injectors, and their arrangement are studied then the diagram of thrust vector angle deviation compare to injection rate, and state of arrangement are calculated. Using of these diagrams, optimum of injection distribution rate, amount of injection, and injectors arrangement obtained and can use for design of LITVC.

This paper focuses on the design and analysis of an injector suitable for a liquid injection thrust vector control (LITVC) system. The LITVC system is used in flight systems to control and divert the thrust vector using the secondary fluid spraying method. For this purpose, various types of injectors were studied and categorized based on the geometry and operating conditions. The centrifugal si...
