DRDO has successfully tested the Hypersonic Technology Demonstrator Vehicle: 6 times faster than the speed of sound.
Congratulations to @DRDO_India for successful flight of the Hypersonic Test Demonstration Vehicle today. The scramjet engine developed by our scientists helped the flight achieve a speed 6 times the speed of sound! Very few countries have such capability today.— Narendra Modi (@narendramodi) September 7, 2020
Missiles have many categories based upon the speed they are referred to as Cruise Missile. they have a shorter range less than 1000km but they generally affect very precision in their range of launch which affects their radar.
The different types of Missiles :
1. Subsonic Cruise Missile - speed less than the speed of air with a speed of 0.8 Mach. Nirbhay of India, American Tomahawk Cruise Exocet of France are well-known examples of subsonic cruise missiles.
2. Supersonic Cruise Missile - the speed of around 2-3 Mach , they are very fast either the same as or faster than the speed of air . Brahmos was developed in collaboration with India with France. they are very effective when fired from the land, sea.
3. Hypersonic Cruise Missile - they travel with a speed more than 5-6 Mach which equals 6 times more than the speed of light it is a next-generation invention. India is trying its efforts to form its missile.
HSTDV (HYPERSONIC TECHNOLOGY DEMONSTRATOR VEHICLE ) which India has developed to test the hypersonic missiles were we are using SCRAMJet Engine for a recent and proper test. 100% Made in India from the coast of Orissa.
Russia has already developed a Hypersonic Missile development. The US, China are also developing their missiles. the missile would travel 7000 km in 5-6 mins.
India still has many aerodynamic challenges for the development of the missile .
Congratulations to @DRDO_India for successfully conducting test flight of Hypersonic Technology Demonstrator Vehicle by using indigenous scramjet engine. This is an important milestone in our quest towards achieving self-reliance. #HSTDV pic.twitter.com/1pC5EGiCBo— Vice President of India (@VPSecretariat) September 7, 2020
