Engines
Overture
Overture is the club's next-to-be manufactured engine, one that prioritized fast, iterative progress. Overture will advance our past engine designs by having a unique modular design, which allows the team to test multiple variations of engine components, including different injectors, nozzle geometries, and even ablative cooling sleeves in order to optimize the engine.
Overture's main goals are to verify that the test stand fluids system is capable of long duration burns, and that Overture has the potential to integrate with a turbopump or flight vehicle in the future.

Echo
Echo is our regeneratively cooled rocket engine 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.
