Hydrazine

Hydrazine ispound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia like odour.. Hydrazine is highly toxic unless handled in solution as e.g., hydrazine hydrate NH2 NH 2 · xH 2 O.As of 2015, the world hydrazine hydrate market amounted to $350 million. Hydrazine is mainly used as a foaming agent in

Analysis of alternatives PROPELLANT FINAL non confidential

A rocket propellant is a substance stored on board of a rocket that at some point in time is used as the propulsive mass that is ejected/expelled from a rocket engine in the form of an exhaust jet to produce thrust. Rocket propellant is used in the same way to produce thrust in missiles i.e. guided weapons.

FIELD TESTING OF PROPELLANTS.

The laboratory screening studies were directed toward a particular chemical or physical measurement which would be adaptable to field testing for the determination of quality of each propellant. The approach to the problem was to develop a go or no go type measurement designed to indicate departure from the specification of a usable propellant.
