A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other. The two propellant components usually consist of a fuel and an oxidizer .
The Vikas (a portmanteau from initials of VIKram Ambalal Sarabhai [5] [6]) is a family of hypergolic liquid fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre in the 1970s. [7] [8] The design was based on the licensed version of the Viking engine with the chemical pressurisation system. [9]
Specific impulse (usually abbreviated I sp) is a measure of how efficiently a reaction mass engine, such as a rocket using propellant or a jet engine using fuel, generates thrust.
Apogee engines typically use one fuel and one oxidizer. This propellant is usually, but not restricted to, [7] a hypergolic combination such as: N 2 H 4 / N 2 O 4, MMH/ N 2 O 4, UDMH/ N 2 O 4. Hypergolic propellant combinations ignite upon contact within the engine combustion chamber and offer very high ignition reliability, as well as the ...
Aerozine is not used as a monopropellant (a propellant that is not mixed with anything). The extra stability conferred by the methyl groups affects reactivity and thrust. In 1980, an accidental leakage of Aerozine 50 resulted in the 1980 Damascus Titan missile explosion. The leak occurred due to puncture of the first-stage Titan fuel tank by a ...
This is a short table intended for use in rocket, rocket engine, etc. of the performance of common propellant mixes. It's intended to have only about 10 entries at most; it is NOT a complete list. Table has been edited to include actual vacuum performance of rocket engines instead of theoretical maximum Isp.
The Orbital Maneuvering System (OMS) is a system of hypergolic liquid-propellant rocket engines used on the Space Shuttle and the Orion spacecraft.Designed and manufactured in the United States by Aerojet, [1] the system allowed the orbiter to perform various orbital maneuvers according to requirements of each mission profile: orbital injection after main engine cutoff, orbital corrections ...
The ascent propulsion system (APS) or lunar module ascent engine (LMAE) is a fixed-thrust hypergolic rocket engine developed by Bell Aerosystems for use in the Apollo Lunar Module ascent stage. It used Aerozine 50 fuel, and N 2 O 4 oxidizer.
