Question: consider following statements:
i) India’s first Advanced Hypersonic Wind Tunnel test facility is in Hyderabad.
ii) PM Narendra Modi inaugurated the facility recently.
iii) India is the third country after United States and Russia to have such facility.
Which of the above are correct?
a) i and ii
b) ii and iii
c) i and iii
d) all of the above
Answer: c)
Context
- The Defence Minister Rajnath Singh recently inaugurated the Advanced Hypersonic Wind Tunnel (HWT) test facility in Hyderabad which is indigenously built by DRDO with participation of local industries.
Facts
- Wind tunnels are large tubes with air blowing through them. The tunnels are used to replicate the actions of an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly.
- The Hypersonic flow is a flow where the speeds are much higher than the local speed of sound. The hypersonic flow is generally defined as the flow at Mach 5 or greater.
- The recently inaugurated Hypersonic Wind Tunnel Test Facility will simulate hypersonic flow over a wide spectrum. It will play a major role in realizing highly complex futuristic aerospace and defence system.
- The state-of-the-art HWT Test facility is “pressure vacuum driven enclosed free jet facility having nozzle exit diameter of 1 metre and will simulate Mach No 5 to 12 (Mach represents the multiplication factor to the speed of sound).
- After America and Russia, India is the third country to have such a large facility in terms of size and operating capability.
