Hypersonic Technology Demonstration Vehicle (HSTDV) - How does it Work?

DRDO has successfully demonstrated the Hypersonic air-breathing scramjet technology with the flight test of Hypersonic Technology Demonstration Vehicle (HSTDV) on 07 Sept 2020 from Dr. APJ Abdul Kalam Launch Complex at Wheeler Island, off the coast of Odisha. How does a HSTDV work? Its high time we know about it.

Lets start with a ramjet, ramjet is an engine which utilises the ram effect (fast approaching) air to compress and generate thrust after combusting the fuel air mixture. A scramjet is similar to ramjet, but with a little difference!

Flying-V : Future Airliners may Look Anew!

Single body fuselage configuration is predominantly familiar and common when coming to airliner's. But this is going to change soon! A team of researchers, engineers and a pilot successfully carried out a first real test flight of the scaled flight model of the energy-efficient aircraft design called the Flying-V.

This is an innovative project being developed by "TU Delft University" and "KLM Royal Dutch Airlines" in collaboration with and "Airbus". According to their predictions this innovative design will typically reduce fuel consumption by 20% compared to today’s most advanced aircraft Airbus A350
