Q. Consider the following statements regarding Hypersonic technology:
1.Hypersonic speed ranges from Mach 1.2 to Mach 5, which is faster than the speed of sound.
2.India has become the fifth country to demonstrate this technology after the USA, Russia, France, and China. .
Which of the above statements is/are correct?
Answer: D
Notes:
Hypersonic speeds are 5 or more times the Mach or speed of sound. Whereas supersonic speeds range from Mach 1.2 to Mach 5.
There are two types of Hypersonic weapons:
- Hypersonic cruise missiles: These are the ones that use rocket or jet propellant through their flight and are regarded as being just faster versions of existing cruise missiles.
- Hypersonic Glide Vehicle (HGV): These missiles first go up into the atmosphere on a conventional rocket before being launched towards their target.
Technology Used: Most hypersonic vehicles primarily use the scramjet technology, which is a type of Air Breathing propulsion System.
Recently, the DRDO successfully tested the Hypersonic Technology Demonstrator Vehicle (HSTDV). India became the fourth country to have demonstrated this technology after the USA, Russia, and China.
