20 LBS THRUST ROCKET ENGINE

this is a small liquid fueled rocket engine derived from a "how to book" it is designed for 20 lbs pounds of thrust 300 psi chamber pressure, propellant feed rate Gasoline .022 lbs per second Oxygen (gas) 0.055 lbs per second water in out at 45 ft per second this engine is not a flight capable it is simply to heavy and the lack of cryogenic fuel means we cant regeneratively cool it so the launch vehicle would have to cary water unless you have some tungsten feel free to comment on what you think have fun!
