Abstract: The Yellow Jacket Space Program (YJSP), the liquid rocketry student organization at Georgia Tech, has a goal of launching a vehicle to the edge of space. The injector is one of the most important components on a liquid rocket engine, directly affecting the performance and efficiency of an engine. YJSP started developing a coaxial swirl injector in January 2023 starting with single element tests followed by subscale demonstrators. Using the data learned in these tests, a 2500lbf flight version was developed for Vespula, targeting a summer 2025 launch to 100,000ft. This paper goes over the development process including waterflow, cold flow, and hotfire tests.
