⭕ hi this is a stentor rocket engine, it was used in a missle called blue steel , it has been used as a demonstration piece, since 1970s, and has been in storage for the past 13 years the engine was running so i believe, it will need some work to get back into comission, but would be great for a hot rod or drag car. or even on the back of a lorry, the large combustion chamber is to produce a fixed thrust of 25,200lb at 45,000 ft and the small chamber produces a smooth variable thrust from 1000lb to 6200lb at 45,000ft it runs on htp and kerosene any questions please contact me .
