UH 25 was used in Ariane rocket versions 2 through 4, and in the Indian GSLV Mk III. UH 25 is a mixture of 75% UDMH and 25% hydrazine hydrate . [ 2 ] It is hypergolic with dinitrogen tetroxide as oxidizer, and both can be stored as liquids at room temperature.
The only rocket-powered fighter ever deployed was the Messerschmitt Me 163B Komet. The Komet had a HWK 109-509, a rocket motor which consumed methanol/hydrazine as fuel and high test peroxide T-Stoff as oxidizer. The hypergolic rocket motor had the advantage of fast climb and quick-hitting tactics at the cost of being very volatile and capable ...
In the case of solid rocket motors, the fuel and oxidizer are combined when the motor is cast. Propellant combustion occurs inside the motor casing, which must contain the pressures developed. Solid rockets typically have higher thrust, less specific impulse , shorter burn times, and a higher mass than liquid rockets, and additionally cannot be ...
