Why it is beneficial to use satellite launch vehicles made of more than one stage?
Advertisements
उत्तर
- The launch vehicle's fuel accounts for the majority of its overall weight.
- As a result, a significant amount of weight must be carried by the vehicle.
- In launch vehicles with multiple stages, the vehicle's initial thrust is provided by the fuel in the first stage. The vehicle's fuel tank will be empty once this fuel is used up. This gradually lowers the vehicle's weight.
Therefore, using satellite launch vehicles with multiple stages is advantageous.
