15th International Electric Propulsion, 1981
A rocket using atomic hydrogen propellant is discussed. An essential feature of the proposed engine is that the atomic hydrogen fuel is used as it is produced, thus eliminating the necessity of storage. The atomic hydrogen flows into a combustion chamber and recombines, producing high velocity molecular hydrogen which flows out an exhaust port ...

Journal of Jet Propulsion, 1954
Theoretically only one type exists; however, due to the selective process of dynamic evolution, four types are known to exist at various rocket establishments. The IDEAL type is the rocket test engineer you see in the movies, ads, and press releases. He is usually clad in protective clothing, wears a face shield, and sometimes sports a supersonic dunce

Development of Soviet Rocket Engines [PDF]
It is not always easy to find the source of even a big river. It is only conditionally that we accept the spring inside a log cabin in a small peat bog near the village of Volgoverkhovye as the source of the mighty Volga. It is perhaps even more difficult to find, back in the depths of the ages, the source of the thought which has today become one of ...
