This is

This site is intended to be the center of information on the development of my rotary rocket engine, U.S. patent 6212876, and the resulting rocket system designs. The engine is an ultra simple rotary rocket with potential for simultaneously achieving 10,000 psi chamber pressure and 400:1 thrust-to-weight ratio for a cost of less than $1 per pound of thrust.
