Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russian rocket engineers) as amyl, is the chemical compound N 2 O 4. It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. Its molar mass is 92.011 g/mol.
Mixed oxides of nitrogen (MON) are solutions of dinitrogen trioxide (N 2 O 3) in dinitrogen tetroxide/nitrogen dioxide (N 2 O 4 and NO 2). It may be used as an oxidizing agent in rocket propulsion systems. [1] Mixed oxides of nitrogen are produced by dissolving nitric oxide (NO) gas in liquid dinitrogen tetroxide. Nitric oxide reacts with ...
NO y (or NOy) refers to the sum of NO x and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NO x, HNO 3, HNO 2, etc.) NO z (or NO z ) = NO y − NO x Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.
Pentaborane was also investigated to be used as a bipropellant with nitrogen tetroxide. [11] In the Soviet Union, Valentin Glushko used it for the experimental RD-270M rocket engine, under development between 1962 and 1970. [12] Other boranes were evaluated as fuels, including propylpentaborane (BEF-2) and ethyldecaborane (REF-3). [13]
A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium.
Pentaborane(9) and diborane + nitrogen tetroxide – Pentaborane(9), a so-called Zip fuel, was studied by Soviet Rocket Scientist V. P. Glushko for usage in combination with nitrogen tetroxide in the RD-270M rocket engine. This propellant combination would have yielded a significant increase in performance, but was ultimately given up due to ...
Monomethylhydrazine (MMH) is a highly toxic, volatile hydrazine derivative with the chemical formula CH 6 N 2.It is used as a rocket propellant in bipropellant rocket engines because it is hypergolic with various oxidizers such as nitrogen tetroxide (N 2 O 4) and nitric acid (HNO 3).
UDMH is often used in hypergolic rocket fuels as a bipropellant in combination with the oxidizer nitrogen tetroxide and less frequently with IRFNA (inhibited red fuming nitric acid) or liquid oxygen. [12] UDMH is a derivative of hydrazine and is sometimes referred to as a hydrazine. As a fuel, it is described in specification MIL-PRF-25604 in ...
