What is glycidyl azide polymer?

What is glycidyl azide polymer?

Glycidyl azide polymer (GAP) is one of the well-known low-molecular weight energetic liquid pre-polymer, which was developed to use as energetic binder, high performance additive and gas generator for high performance smokeless composite propellant and explosive formulations.

How is hydroxylammonium nitrate made?

In this method, hydroxylammonium nitrate is produced from hydroxylammonium sulfate or hydrochloride by an electrolysis method which uses cation and anion exchange resins and a double decomposition reaction.

What is HAN chemistry?

Hydroxylammonium nitrate or hydroxylamine nitrate (HAN) is an inorganic compound with the chemical formula [NH3OH][NO3]. It is a salt derived from hydroxylamine and nitric acid. In its pure form, it is a colourless hygroscopic solid.

What is E green propellant?

Green propellants are low toxicity, high energy liquid rocket propellants that will offer a high-performance, high-efficiency alternative to conventional chemical propellants for future spacecraft. Green propellants are attractive as possible substitutes for traditional hazardous propellants because of several factors.

What is the most eco friendly rocket fuel?

“Liquid methane and liquid hydrogen can provide high thrust in a launcher that is still relatively compact.” Despite being a very potent greenhouse gas, methane as a rocket fuel also seems to be quite environmentally friendly because of its burning efficiency.

What is green rocket fuel?

According to him, ISRO is also looking at rocket engines powered by hydrogen peroxide as a mono-propellant or as a bi-propellant along with ethanol. ISRO is also developing another green fuel – LOX/Methane- liquid oxygen as oxidiser and methane as fuel.

What are the properties of hydroxylamine?

The material is a white crystalline, hygroscopic compound. Hydroxylamine is almost always provided and used as an aqueous solution….Hydroxylamine.

What Colour is rocket fuel?

— SpaceX’s next Falcon Heavy launch will carry a satellite designed to test a new type of rocket fuel, the first ever “green” propellant in space. Only it’s not so green. The fuel — a hydroxyl ammonium nitrate fuel/oxidizer mix called AF-M315E — is salmon-colored and, according to NASA, less toxic than caffeine.

Which fuel is used in ISRO?

ISRO has also developed ISROSENE, which is a rocket-grade version of kerosene as an alternative to conventional hydrazine rocket fuel. Queried about the green option for its solid fuel-fired engines, Sivan said the work towards this end is also progressing well.
