Working of Solid Propellants
By changing the shape and size of the perforation we can control the rate and duration of
burning and thus control the thrust. More the thrust required, larger will be the perforation but the fuel will burn for a smaller time. Lesser the thrust required, smaller will be the perforation but the fuel will burn for a very long time.The burning period and the thrust depends upon the type of perforation in the fuel.
Let us see the different classifications of solid propellants and merits and demerits of using solid propellants.
