Why it is beneficial to use satellite launch vehicles made of more than one stage? Answer the question
Answers
The bulk of the weight in satellite launch vehicles is contributed by fuel.
This means that vehicles have to carry a large fuel weight during their journey.
In order to overcome this situation, heavy load is carried by vehicles, during their entire journey are provided with more than one stage.
As a result, the decreases the weight of vehicle step by step after launches.
Consider a launch vehicle, for example, with two steps.
In the first stage, the fuel and engine are used to launch the vehicle.
This gives the vehicle a specific speed and takes it to a certain height.
Once the fuel is exhausted in this first stage, the empty fuel tank and engine are detached from the main body of the vehicle and fall into either a sea or an unpopulated land.
As the fuel is exhausted in the first sage, the fuel in the second stage is ignited.
The vehicle, however, now contains only one stage.
The vehicle can move at a higher speed with a reduced weight."
