Echo Series
Echo is our upcoming series of regeneratively cooled rocket engines meant to teach our team about engine cooling. By having the first iteration of Echo be water cooled we will be able to verify our chamber combustion performance and ensure high safety margins.
Initial tests with Echo will include injector performance testing, thrust characterization, and verification of our in house cooling simulations. LRI believes in the idea that the best way to learn about rocketry is to make fast, tangible progress and learn from it. Testing Echo will eventually lead to our goal of developing a rocket engine capable of powering a small-scale flight vehicle.
Grunt
GRUNT is the first collegiate liquid rocket engine in Illinois, and LRI's earliest attempt at liquid engine design. A simple thrust chamber assembly concept ÅŸs used to verify our injector concept and demonstrate our ability to build liquid rocket engines. The engine has successfully passed a cold flow test.
Grunt Status
LRI is in the final stages of planning the Grunt, and LRI's, first hotfire! The team will drive down to the Friends of Amateur Rocketry test site at the Mojave Desert in early August. Stay tuned on our social media for updates!
