Purdue SEDS have performed a 2nd hot fire of their lOX/LCH4 rocket, this time performing a full duration burn test. The 1100lbf (4893N) engine will propel the rocket to ~45,000ft later in the year.
Video Caption: NOTE: The small fire on the panel is the solid propellant igniter that shot out, bounced back up, re ignited, and snagged itself on a line.

Boomie Zoomie is Purdue’s liquid rocket that will fly over 30,000 feet using its 1100lbf liquid oxygen – liquid methane engine. The rocket weighs approximately 110 pounds, 6.5 inches in diameter and over 10 feet tall.
The test was conducted at Purdue’s Zucrow Propulsion Labs. We tested on a temporary set up as we prepare to transfer the equipment to a launch trailer.
This was our second hot fire attempt after our liquid oxygen tank failed to pressurize the first time. Unlike the first attempt debris or air got into the condenser and created a blockage restricting the liquid methane flow into the rocket. Instead of scrubbing it was determined we had enough propellant to burn for 5 of the 8 seconds.
This rocket was design and fabricated by Purdue Space Program a section Purdue SEDS.
Co-axial tanks are in! Most rockets have one tank for the oxidizer and another separated tank for the fuel. In this configuration, the fuel tank is inside the oxidizer tank. This configuration saves 5% of total rocket mass weight and simplified plumbing in our set up. The outer tank will hold liquid oxygen and the inner tank will hold liquid methane. This configuration has never flown in a student rocket before with cryogenic fluids! @purdueengineers #rockets #fuel #machining #engineering #engineers #spaceportamericacup #space #spacex #blueorigin #purdue #purdueuniversity #purduebound #purduealumni #purduewedidit #aluminum #welding
Man the setup at Purdue is pretty epic!

Well, what a weekend it has been, both Purdue SEDS and the SDSU Rocket Project conducted successful tests of their own respective LOX/LCH4 rocket engines or methalox engines as they are sometimes called.
Both teams intend to fly these rocket engines in the FAR-MARS prize in May and therefore are eligible to win up to $100k of prize money!
Awesome work being done by both and great to see liquid methane being given a go by student teams.
