What Are The Advantages And Disadvantages Of Liquid Fuels And Solid Fuels Used On Missiles?
Nov 01, 2017

Liquid fuel rockets are generally done for a long time, small and medium thrust work, and even allow parking, because the liquid fuel molecular activity is strong, chemical stability is low, the basic must be low temperature storage, and the rocket itself is difficult to do, so basically Fuel tank without fuel, to use when the re-filling, so the liquid rocket preparation time is long.

Liquid fuel generally refers to the liquid oxygen and hydrazine or liquid hydrogen, hydrazine of the general formula is: R-NH-NH2, NH2-NH2 hydrocarbon derivatives collectively. Hydrazine combustion energy is higher than liquid hydrogen. Solid Fuel Such as hydrazine hydrate, dimethyl hydrazine, dimethyl hydrazine, the current combustion energy of hydrogen has no advantage, and because the hydrogen molecules are extremely small on the erosion of various containers terrible, not suitable for long storage.

What is the difference between a solid fuel and a liquid fuel for a missile? Which is more advantageous?

1. Nitrocellulose, also known as nitrocellulose, Solid Fuel scientific name cellulose nitrate, from cotton fiber or wood fiber in the nitric acid "nitrification" made

2. nitrocellulose scientific name glycerol trinitrate, glycerol (glycerol) and nitric acid "nitrification" made

3. Other additives Solvents, plasticizers, chemical stabilizers, combustion stabilizers and combustion governor, process additives

Composed of oxidants, metal fuels, and polymeric binders

1. Oxidants are the most commonly used: ammonium perchlorate, the other with potassium perchlorate, sodium, lithium, ammonium nitrate, potassium, sodium, lithium

2. Metal fuel is the most commonly used aluminum, Solid Fuel the other with hydrogen, carbon, lithium, beryllium, boron, magnesium ... ...

3. Binder to oxidants and metal fuels and other solid particles together to become a flexible matrix, and provide C, H and other fuel elements. Polyvinyl chloride, Solid Fuel polyurethane, polybutadiene and so on

4. The curing agent makes the above things solid

5. Plasticizer to reduce viscosity, increase mobility, improve mechanical properties
