The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust. The energy required can either come from the propellants themselves, as with a chemical rocket, or from an external source, as with ion engines.
2-Dimethylaminoethylazide (DMAZ) is a liquid rocket fuel being investigated for use as a spacecraft propellent to replace the toxic, carcinogenic monomethylhydrazine. [1] It is a member of the competitive impulse non-carcinogenic hypergol (CINCH) family which were assessed as a replacement for hydrazine -derived propellants.
Nitrous oxide fuel blend propellants are a class of liquid rocket propellants that were intended in the early 2010s to be able to replace hydrazine as the standard storable rocket propellent in some applications. In nitrous-oxide fuel blends, the fuel and oxidizer are blended and stored; this is sometimes referred to as a mixed monopropellant.
Normal propellant-grade concentrations, therefore, vary from 70 to 98%, with common grades of 70, 85, 90, and 98%. [1] The volume change of peroxide due to freezing varies with percentage. Lower concentrations of peroxide (45% or less) will expand when frozen, while higher concentrations (65% or greater) will contract. [2]: 4–39
Unsymmetrical dimethylhydrazine (abbreviated as UDMH; also known as 1,1-dimethylhydrazine, heptyl or Geptil) is a chemical compound with the formula H 2 NN(CH 3) 2 that is primarily used as a rocket propellant. [4] At room temperature, UDMH is a colorless liquid, with a sharp, fishy, ammonia-like smell typical of organic amines.
Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of nitric acid ( H N O 3 ), dinitrogen tetroxide ( N 2 O 4 ) and a small amount of water . The color of red fuming nitric acid is due to the dinitrogen tetroxide, which breaks down partially to form nitrogen dioxide .
Polybutadiene acrylonitrile (PBAN) [1] copolymer, also noted as polybutadiene—acrylic acid—acrylonitrile terpolymer [2] is a copolymer compound used most frequently as a rocket propellant fuel mixed with ammonium perchlorate oxidizer. [3] It was the binder formulation widely used on the 1960s–1970s big boosters (e.g., Titan III and Space ...
A monopropellant rocket (or "monochemical rocket") is a rocket that uses a single chemical as its propellant. [1] Monopropellant rockets are commonly used as small attitude and trajectory control rockets in satellites, rocket upper stages, crewed spacecraft, and spaceplanes. [2]
