Abstract
Four embodiments of high-thrust rocket engines, each having separate propellant delivery apparatus for each propellant to be delivered to the engine thrust chamber, are illustrated herein. One engine is designed to provide a high thrust using only one fuel and one oxidizer. The other three engine embodiments are all designed to use different propellants having different densities during different portions of a rocket flight. Each of these additional engines includes the basic structure of the first. The first engine is thus not only an effective engine, but also a building block that can be easily modified to provide an engine capable of operating effectively with different propellants.
