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.
