5. The Hypersonic cruise vehicle test puts India in elite club, Discuss the key features and significance of it to India. (250 words)
Reference: The Quint
Why the question:
The Defence Research and Development Organisation (DRDO) conducted a flight test of the hypersonic technology demonstrator vehicle (HSTDV). Thus the question.
Key Demand of the question:
The question is Straightforward one must explain in detail two key features and significance of the hypersonic rose vehicle test.
Discuss – This is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.
Structure of the answer:
Explain what hypersonic cruise vehicle is.
Features of the HSTDV:
The hypersonic cruise vehicle was launched using a proven solid rocket motor, which took it to an altitude of 30 km, where the aerodynamic heat shields were separated at hypersonic speed.
It attained a speed of Mach 6 (6 times the speed of sound) i.e, nearly 2 km/s.
It uses a scramjet engine, in which air enters at supersonic speed and comes out at hypersonic speeds.
The vehicle reaches a certain altitude, then cruises and also, reaches very high temperatures, up to 1,000°-2,000° Celsius, during re-entry.
The DRDO has successfully demonstrated the hypersonic air-breathing scramjet technology.
With this technology, cruise missiles can now travel at hypersonic speeds.
Testing paves the way for the development of more critical technologies, materials and hypersonic vehicles. It will help in the development of hypersonic cruise missiles.
Most engines use the ramjet engine which operates at supersonic speeds of up to Mach 3.
This puts India in a select club of nations that have demonstrated this technology.
Conclude with its relevance and importance to India.
