India’s first Hypersonic Technology Demonstrator Vehicle being tested

Hyderabad – A series of tests are underway for India’s first Hypersonic Technology Demonstrator Vehicle (HSTDV) and this will get a boost with the wind tunnel facility coming up here.

Defence Research and Development Organisation (DRDO) is confident that HSTDV, which has already achieved 6.5 Mach, will achieve its aim of scramjet flight for 20 seconds.

Mach is commonly used to represent the speed of an object when it is travelling close to or above the speed of sound.

V.G. Sekaran, director general (missiles and strategic systems), DRDO, told reporters here Wednesday they have already achieved some milestones in terms of engine development.

“HSTDV would give us a lead in hypersonic vehicle design, scramjet, material technology and how to manage environment which is peculiar to hypersonic flying engines,” he said.

He said work on the wind tunnel required for tests had started and it would be ready in one-and-half years. He was confident this would reduce the development cycle in hypersonic programme.

Issues related to a long term hypersonic programme in the country will be discussed at a two-day international symposium beginning here Thursday.

The sixth symposium on “Applied aerodynamics and design of aerospace vehicles” will discuss the roadmap for some of the futuristic hypersonic programmes.

Prahlada, vice chancellor, Defence Institute of Advanced Technology, said India was looking at extreme technologies in aerodynamics aimed at making aircraft efficient, green and quiet with smooth flying.

He said India required Aerostat and aerodynamics in a big way. Two types of Aerostat were developed and deployed which can go up to one km. Aerostat which can go up to four km and carry two tonnes of load were under development, he added.

“Our aim is it develop an Aerostat which can go to 10 km and lift 10-20 tonnes in bad terrain,” he said.

A series of Aerostats will be developed that can be used both for civilian and military purposes.

Prahlada said work was also on to develop micro air vehicles, emulating how some birds like hummingbird and bumblebee fly.

“These birds have very special aerodynamic control. We have not been able to simulate similar aerodynamics for unmanned micro air vehicle. We are looking at using smart material which works like these birds,” he said.

He pointed out these birds can stay where they are and keep lifting without moving forward. Normally when an aircraft lifts, it has to move. Both forward motion and lift are linked but in case of birds, it is delinked, he added.

What's so mysterious about that? Don't helicopters do that as well? Fixed wing aircrafts cant do that, but birds/bees/helicopters have moveable wings.

Helicopters get the lift based on Bernouli principle

In case of Aeroplane the wing is fixed, But in case of helicopter the wings are like rotating(rotor) to get the lift.

But the minuture uav's do not use this principle, they use their wings to do some complex motions so that they can control roll, pitch and Yaw. And also to get the lift.

@Srinivas : Why did you add a picture of Brahmos-2? The article you linked has a model of the HSTDV.

If you see the tip of the missile it is actually HSDTV

HSDTV is the technology and Brahmos 2 missile is the actual application, I thought people will get a good idea so I posted it.

Nope . HSDTV and Brahmos II are two entirely different programs .
 
China also tested this,so whats so special about this?

Its indigenous and that's what makes it special besides, ISRO had already flight tested its Scramjet engine way back in 2010 achieving a speed of Mach 6.

What exactly it is?An aircraft?The article says that it is a vehicle......

?? I quite dint get your question. However I guess you are curious to know about ISRO's achievement.

Please google "Advanced Technology Vehicle (ATV-D01)" to read more about it.

ATV D01 had a passive scramjet engine .

Mach 6 was not achieved by the scramjet but by the rocket .

Sorry if I sound Ignorant. Could you please explain how different is the term Engine reaching a Mach 6 feet and the Rocket powered by the same?

The scramjet is attached to the ATV D01 as a payload . The whole purpose of the experiment was to study the passive flight of the scramjet .

It was the sounding rocket that took the scramjet module to Mach 6 not the other way around .

Hypersonic Brahmos engine is ready what we lack is materials to protect avionics in high temperature generated out of air friction.
