Abstract

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 single-base injector was selected as the design basis due to its uniform spraying, the ability to transfer higher flow rates, and relatively smaller geometric dimensions. In this process, in addition to defining three groups of non-dimensional geometric parameters, design was made based on engineering calculations and numerical solutions in FLUENT. The injector with proper outlet speed and the lowest pressure drop was selected as the final product of the design. Then, three different types of configurations were studied and the amount of thrust vector deflection created by each configuration was calculated. Findings were validated using the results reported by the previous researches, and finally, the best spray belt was introduced.
