Student Development of a Liquid Oxygen, Liquid Methane Sounding Rocket and Launch Infrastructure
Overview
Boomie Zoomie is a student-designed and developed rocket from PSP Liquids. It is the first liquid-liquid rocket designed entirely by Purdue students to carry a 2.2 lb payload to 45,000 feet. BZ meets the requirements set out in the 2017-2019 FAR MARS Liquid Rocket Competition.

Special thanks to Dan Moser for his insight and help in the design and fabrication of this chamber.
Co-Axial propellant tanks saved 5 pounds in structure and plumbing in our design. Our methane tank is almost completely submerged inside of our oxygen tank. This is made possible by the boiling point of liquid oxygen being slightly warmer than the freezing point of methane. The tanks are responsible for holding the propellants at 1000 psi to deliver enough mass to the engine.
Our airframe was made out of 6 inch aluminum pipe. While not the lightest, it was the most cost effective option that we could easily manipulate and machine. The airframe is designed to be swapped out with future designs and with field prep in mind. For example, the recovery team can check out the packed parachute without interfering with the pressurization team.
