Initially, the fuel and oxidizer were fed in such a way that the chamber pressure during combustion was around 9 bar. Upon successful completion, the hot flow testing was simultaneously carried out for two cases. The four broad categories into which liquid engines may be placed are: 1. Cold flow testing of the engine was done for a chamber pressure of 4, 6, 8 and 10 bar. A space-tech startup headquartered in Chennai, India, successfully test-fired the worlds single-piece 3D-printed engine. Liquid rocket engines differ greatly depending on mission, materials of construction, and launch vehicle design. However, the maximum chamber pressure the engine can withstand was not limited to 20 bar, and it was capable of withstanding a chamber pressure of 30 bar during combustion. ![]() The engine was designed to withstand a chamber pressure of 20 bar. This project aims to design, fabricate and test a small liquid rocket engine using kerosene and gaseous oxygen. Liquid rocket engines are widely used in the aerospace industry for their good controllability. ![]()
