This is a the largest engine i ever built, resting on the test stand after becoming the state boulder toss champion. Think the final numbers after pump head calculations with the brayton cycle was 55,000hp at the turbo, 650,000 lbs of thrust at the load cell. Took me about 4 months, with one of those months working 16hrs a day to build the turbos, regen circuits, preburners, injectors, controllers, harnesses, and integrate it all. I was homeless and sleeping in the shops parking lot when i wasnt turning wrenches. Flew for a few glorious minutes before splashing down in the Atlantic and sinking peacefully into the deep blue.
