Hybrid Liquid-Solid Propellant Rocket
Top Right: 1. Liquid Oxidizer 2. Injection Jets for
Oxidizer 3. Combustion Chamber Constrictions 4. Ignition
Mechanism Solid fuel shown running along sides of
combustion chamber (dark color). "Schaumkohle" (porous
compressed coal) are suitable as fuel as would a mixture
of Aluminum power and polyurethan combined with liquid
nitrogen tetroxide. Thrust controlled by amount of
oxidizer injected. Hypergolic mixtures would require no
ignition system. Alternately, oxydizers could be solid and
fuel liquid. "Nichts ist unmoeglich" Nothing is impossible
