The Yellow Jacket Space Program (YJSP) is a student run club at the Georgia Institute of Technology with three goals: to promote university level space research, prepare students for the space industry, and advance the frontiers of launch vehicle development. To achieve this, the Propulsion team has been developing the feed system, engine chamber and test stand for the program’s first Liquid Oxygen/Kerosene liquid bi-propellant rocket engine. This engine is pressure-fed and heat-sinked, capable of producing 15kN of thrust. As part of the development program for the liquid-fueled sounding rocket, the Avionics/Flight Dynamics team also require a solid-fueled testbed vehicle for flight testing subsystems. The solid rocket will flight-test 3-degree-of-freedom aerodynamic controls at comparable flight regimes to the liquid-fueled vehicle. The vehicle will also be designed to test communication, data-gathering, and recovery systems. This report describes the conceptual and preliminary design and development of the Propulsion team’s liquid rocket engine as well as the Avionics and Flight Dynamics teams’ testbed vehicle. This report concludes with a discussion about applying the same design methodologies to larger and more complex vehicles
