- Abstract
Space propulsion mainly uses reciprocating pumps that are fully integrated with small-scale applications. In this paper, the specific specifications and designing factors that should be met by rocket engine fuel pumps are demonstrated, and a comparative study is formed of the suitableness of all the necessary kinds of pumps to be used with rocket engines and their applications. Furthermore, it examines a piston pump intended to refuel the liquid fuel nozzles. Due to the performance of this pump, different parts and its performance have been evaluated. The design of the pump is discussed such that after completing the design steps according to the pump performance, a numerical solution of the stress and strain applied on the inner wall of the cylinder is performed according to its performance under internal pressure. Then, considering the consistency of the body material and the same pressure and heat applied to the cylinder and piston, a sample of the cylinder and piston is analyzed in finite element modeling technique and the modeling results obtained from the simulation are presented.
