Question

What are multistage rockets? What are their advantages?

Answer 1

A multistage rocket or step rocket is a launch vehicle that uses two or more rocket stages, each of which contains its own engines and propellant. A tandem or a single stage is mounted on the top of another stage or a single stage is mounted parallel along the other stage. The result is effectively two or more rocket stacked on top of each other or attached next to each other. These are known as multistage rockets.

Their advantages are as follows:

1) Each stage can use different type of motor

2) The total weight of the rocket is reduce as the rocket rises.

3) Multistage rocket has a bunch of thrust. Fuel causes thrust and so when it drops to another stage there re more thrust since the fuel just keeps burning

4) The main advantage is that it drops useless weight and goes faster.
