Question

Write notes on chemical propellants used in the propulsion system of rockets.

Answer 1

Propellant is the chemical substance used in the production of energy or pressurized gas that is subsequently used to create movement of a fluid or to generate proportion of a vehicle or rocket.
Normal charges are enthusiastic materials and consist of a fuel like gas, fly fuel, rocket fuel and oxidizer charges are used or in any case disintegrated to deliver force gas.

Complete step by step answer:
Chemical propellants = The propellants are chemical materials which on ignition offer thrust for the Rocket to transport forward.
Propulsion structures for Rockets used chemical propellant. These propellant may be stable gas, liquid or hybrid (solid).
Solid (stable) propellant= The stable propellants are composed of stable gas and a stable oxidizer. These are in addition divided into classes-
a) Composite propellants= These are stable solid propellants which use polymeric binders consisting of polymethane or polybutadiene as a gas and stable oxidizer consisting of Ammonium perchlorate Nitrate or chlorate.
b) Double Bass propellant= These are stable solid propellant which specifically use nitro-glycerine and nitrocellulose.

1. Liquid propellants= These include an oxidizer consisting of liquid oxygen or nitrogen acid and a gas consisting of kerosene, alcohol, hydrazine, all liquid hydrogen. Example Ethanol, hydrazine, hydrogen
2. Mono propellant= The propellant in which a single chemical compound acts as fuel as well as an oxidizer are called mono propellants. Example hydrazine, nitromethane
3. Bi propellants= These are propellants in which the gas and oxidizer are saved one at a time however are allowed to mix on the time of combustion. Example kerosene and liquid oxygen
4. Hybrid propellant= These are the propellants which include stable gas and liquid oxidizer. Example acrylic rubber

Note:
Rocket charge is the reaction of a rocket. This response mass is catapulted at the most noteworthy attainable speed from a rocket motor to create push. The energy required can either originate like a rocket or from an outside source likewise with particle Motors.
