Liquid apogee engine The apogee engine traces its origin to the early 1960s, when companies such as Aerojet, Rocketdyne, Reaction Motors, Bell Aerosystems, TRW Inc. and The Marquardt Company were all participants in developing engines for various satellites and spacecraft. Derivatives of these original engines are still used today and are continually being evolved and adapted for new applications. A typical liquid apogee engine scheme could be defined as an engine with: To protect the spacecraft from the radiant heat of the combustion chamber, these engines are generally installed together with a heat shield. Apogee engines typically use one fuel and one oxidizer.
