Vikram S rocket

🔆Vikram S rocket

✅ Why in News:  On November 18, 2022, Hyderabad-based Skyroot Aerospace scripted history by becoming the first private Indian organisation to launch a rocket from Indian Space Research Organisation (ISRO)’s launchpad in Sriharikota.

▪️Vikram S rocket:

✅It is a part of Mission Prarambh, which means the beginning.
✅It is a sub-orbital rocket, which reached outer space and then splashed into the sea.
✅Has payload capacity of up to 300 kilograms.
✅Vikram-S used solid fuel-ammonium perchlorate, which is not completely green fuel.
✅With Vikram-2, it is planned to use liquefied natural gas (LNG), which is greener compared with traditional kerosene fuel.

▪️Mechanisms of Vikram S:

✅There are four spin thrusters, which will generate the rocket’s spin and stability so that it doesn’t deviate from the trajectory.
✅Max-Q is the maximum stress on the rocket and is experienced during the lift-off.
✅At around 23 seconds, the rocket achieves five times the speed of sound or Mach 5.
✅‘Apogee’ is the maximum point after which it descends, falls back and splashes down into the sea.
✅It takes around two and a half minutes to reach the Apogee and another two and a half minutes to splash down.

▪️Technologies used:

✅carbon composites: porous structure made of carbon and carbon fibre and four times lighter and has higher strength than steel.
✅The lighter the rocket, the more payload we can use.
✅3D printing: reduces the cycle time by 90 per cent compared with traditional methods and allows to build complex shapes.
✅Cycle time is the time required to manufacture a component.
✅Cost-effectiveness
✅Efficient technology
✅Utilising existing govt infrastructure
✅Operating out of India

▪️About Skyroot Aerospace:

✅It is an Indian private aerospace manufacturer and commercial launch service provider headquartered in Hyderabad.
✅Mandates: cutting-edge innovation and cost-effectiveness
Next launch will be Vikram-1, an orbital vehicle that puts satellites into orbit.
✅Vikram-2 will have a higher capacity than Vikram-1.
✅Skyroot Aerospace focuses on reusability of rockets.
