Dr Prahlada, Director, Defence Research and Development Laboratory (DRDL) stands near the Prototype Hypersonic Technology Demonstration Vehicle (HSTDV)






India has unveiled a model of its highly ambitious hypersonic technology demonstrator vehicle. The country's Defense Research and Development Laboratory is carrying out study work into a hypersonic air vehicle possibly using a dual-mode ramjet/scramjet engine. The vehicle fore-body and intake ramp configuration are clearly visible, and reflect airframe-engine design combinations intended for flight in the Mach 5-7 regime. One option would be to launch on a ballistic missile with the test vehicle being deployed at around 20 km. (12.5 miles).

Bangalore-Delhi in 20 minutes by hypersonic jet





India-made & faster than Concorde

At first glance, this hypersonic jet would pass off as a blend of an aircraft and a missile. “We are working on the design with a seed money of Rs 15 crore. This is one of the biggest challenges ever in aeronautics. We have identified the team and are networking to build a database on hypersonic systems,” said Prahlada, the director of DRDO’s Defence Research and Development Laboratory, Hyderabad.

The scientists are looking at early 2007 for the first major milestone: the flight of a technology demonstrator for 20 seconds. A successful flight would prompt requests for more money: at least Rs 200 crore to enhance the design and development facilities and Rs 500 crore for a prototype.

“We plan to hoist this 7-metre vehicle into the skies with the help of a rocket and turn on its engine for hypersonic flight. The engine will scoop in air (oxygen) to burn the fuel during the flight and so we have advantages in terms of weight of the vehicle (because of reduced fuel) and intake of oxygen from the atmosphere. The challenge is to generate the thrust at very high speeds,” Prahlada said.

As chairman of the Hypersonic Technology Demonstration Vehicle, Prahlada is keen to expand his team. “We have 100 scientists, but we need at least 500 of them. In principle, we at DRDO, Isro and some academic institutions have agreed to set up a hypersonic technology centre. We will put together about Rs 50 crore for this facility where experts will pool in all data on complex technologies involved,” he said.

Aerospace experts from DRDL, Isro, the Indian Institute of Science, Bangalore, and a couple of IITs form the core group for the craft. “The momentum is picking up. My colleagues in Isro are keen to reduce the cost of launching satellites and have given us inputs on the design. We are trying to draw Indian engineers working abroad into the team,” Prahlada said.

So far, only two groups worldwide have reported success with such high-speed vehicles. Nasa’s X-43 unmanned aircraft hit a record 6,600 mph on November 16, 2004, during its 10-second flight. Carried by a modified B-52 bomber, the 12-ft-long wedge-shaped craft was released off the California coast and then propelled to an altitude of 110,000 ft by a Pegasus space booster. The X-43 fired its experimental engine for about 10 seconds, travelling at speeds approaching 10 times the speed of sound.

Thiruvananthapuram, June 28 : Work on India's first hypersonic wind tunnel (HWT) is under way at the Vikram Sarabhai Space Centre (VSSC) here. Only a handful of countries can boast of an HWT.

Scientists at VSSC are now burning the midnight oil because the HWT is to become a vital ingredient in further development of India's space programmes particularly when India is looking at reusable launch vehicles.

Wind tunnels have undergone enormous development over the years. The current breed of supersonic wind tunnels (SWT) marked the development of turbojet which ushered in an era of supersonic aircrafts that travel two or three times the speed of sound.

Hypersonic travel is expected to be 5-25 times the speed of sound.

The investigations that are carried out in the wind tunnel include total aerodynamic characteristics of aircraft models and their components including tests with engine jets simulation pressure distribution over models surfaces, models of inlets and aircraft with flow through in the internal channels, aircraft components interference during their separation and heat exchange parameters.

The SWT produces supersonic speeds (Mach numbers up to five) while in the HWT Tunnels the Mach numbers between five and 15.

man there is so much critisism for this project on this thread

just wait for the results people

Another new article ...



The Defence Research and Development Laboratory here has begun work on a next-generation aircraft that would fly at hypersonic speeds, that is, seven to ten times faster than the speed of present aircraft.

“This month, we have established a sophisticated engine test complex to test the engine on the ground,” DRDL director Mr Prahalad told The Statesman. This computerised system would test 10 engines in the next one and a half years.

.... fly at least at 7,000 km per hour at an altitude of 30 km,” Mr Prahalad said.

Towards this end, Mr Prahalad has constituted a specialist core team comprising 35 of the DRDL’s best scientists. One fifty more are directly associated with the project. This team is already in the process of working out the aerodynamics, structures, engines, materials, needed for this aircraft to take off.

These elements are absolutely critical as hypersonic speeds cause rapid increase in temperatures because of the air flowing to the aircraft’s surface at several times the speed of sound.

“We are developing the technology needed to create a situation where hypersonic speeds are a reality. For this, both the science and the technology have to work. We are focussing on aerodynamics and system engineering,” Mr Prahalad explained.

Only three other countries — USA, China and Russia — are actively pursuing this concept.

Thanks for resurfacing this old thread Martian.

Here's some new news

New Delhi, Feb 22 (PTI) The Indian Space Research Organisation (ISRO) has successfully demonstrated the supersonic combustion ramjet (SCRAMJET) technology, Lok Sabha was informed today.

The next step in development of this engine is a flight test of an integrated SCRAMJET propulsion module, comprising air-intake, combustor and nozzle, in a two-stage RH-560 sounding rocket, Minister of State in PMO Prithviraj Chauhan said during Question Hour.

Regarding the demonstration of the technology, he said a series of ground tests had been completed successfully on a supersonic combustion ramjet engine. During these tests, a stable combustion was achieved for nearly seven seconds at supersonic speeds corresponding to an inlet Mach number of six, that is six times the speed of sound.

There's a very large Superiority Complex going around on this thread.

Anyways I think it's good that nations like India and China are making an effort to catch up to the United States of America in terms of technological advancements, and I was always a fan of the Su-30 MKI.

Shattered OUT...

Yeah right India and china developing hyper plane they cant even produce a fighter jet of their own
so if I make a model out of plastic of a aircraft and do wind tunnel tests I am at the same stage as India and china are sorry but that doesn't qualify as having or producing a hyeprplane aircraft.


Thats a pretty ignorant comment considering some of our best designers and engineers are indians and chinese.

Nice to see this thread bumped up again...


This sounds very ambitious (in a good way) for India. It's good to see other nations pushing this kind of high speed technology.

Any idea when the actual test flight will be?

I wouldn't underestimate India if I were you, you might be in for a rude awakening.

India should concentrate on eradicating the poverty in which still hundreds of millions of its citizens live, rather than spend money on such expensive projects.

But no doubt, India has a lot of excellent physicists

But you could say the same about any country. 'Money would be better spent on health, public transport and fighting crime in the UK','money would be better spent giving Americans a national health service' etc etc. Your argument should be 'Aerospace money would be better spent on the less well off citizens of the world' for it to be valid in any way. Singling out India, or any one country, is just rubbish.

Th problem is that most foreigners(non-indians) under-estimate India and most Indians(me included
) I now feel over estimate India!!

Got to find some middleground..

Waynos, that was a terrific rejoinder!


In the same vein, Arado, I would like to add, why hasn't US of A cleaned up their Ghettos first? They should have spent the money they used up sending probes to Mars, on the poor of America, the suckers in New Orleans and the backstreets of New York!! So just chill.

Way to go INDIA ! You're the future Superpower!!!

maybe erradicating poverty is as conflicted as the infinity theory.

Eradicting poverty is a more of a social process than just infusing loads of cash all the item..
But believe me, its happening.. I live here!!!

If the growth rate rate is sustained for a few decades, then it'll happen..

Another article dated August 8, 2002 that i found :

Indian rocket scientists claim to have designed a reusable space plane, dubbed Avatar, which they plan to use for launching satellites at very extremely low cost and taking tourists on rides into space The Times of India has reported.
According to the report, work on Avatar, has been conducted under tight security due to its military potential. In early July, the project was publicily announced in the United States by retired Air Cmdr Raghavan Gopalaswami, a former chairman of India's Bharat Dynamics Limited and the central figure behind the project which is being financed by India's Defence Research Development Organisation (DRDO).



The project team includes scientists from DRDO - which has designed various missiles for India's defence forces including the Agni and Prithvi missiles. In addition, another Hyderabad-based company CIM Technologies is participating in the project.

The Times of India report says that the Avatar uses a unique design that enables the spaceplane tp produces its own fuel in flight and has been patented in India. Applications for registration of the design have also been filed with patent offices in the United States, Germany, China and Russia.

Weighing only 25 tonnes - 60 per cent of which is liquid hydrogen fuel - Avatar is said to be capable of enterinng into a 100-km orbit in a single stage and launching satellites weighing up to one tonne.

Taking off horizontally like a conventional airliner, Avatar will use a combination of turbofan, ramjet and scramjet engines to reach a cruising altitude of 10 kilometres before a cryogenic rocket engine takes over for the final push into space.

The mission over, it de-orbits, re-enters the atmosphere and lands on own power like an airplane. A single Avatar can perform 100 such missions in its life, which means 100 tonnes of payload in space.

According to the report, the critical feature of Avatar is that it does not carry any liquid oxygen at take off. Instead, the entire 21 tonnes of liquid oxygen required for the rocket flight will be produced during an initial hour long cruise through the atmosphere - where at eight times the speed of sound, Avatar will suck in air before separating the oxygen and liquifying it for storage.

Mr Gopalaswami told The Times of India that rather lifting satellites, the spaceplane can be fitted out to carry passengers, and that no special training would be needed, as "it would be like going in a Boeing 747."

Moreover, a trip into space on an Avatar would cost only a fraction of the $20 million that Dennis Tito paid Russia earlier this year for his trip on a Soyuz to the International Space Station.

Although all concepts used in Avatar have been mathematically proven and an engineering design has emerged, Gopalaswami told The Times of India that India would not be able to buuld Avatar alone and that international cooperation for both financing and technology would be essential if Avatar was to become a reality.

Meanwhile, the Avatar team in India will go ahead with a scaled down version called "mini-Avatar" and weighing just three tonnes at take off. To be built by CIM technologies in about five years, mini-Avatar will not go into space but will demonstrate all technologies used in Avatar including oxygen collection.

"It will use technologies available within the country," Gopalaswami said including the core engine Kabini developed for a light combat aircraft.

Gopalaswami said the idea for Avatar originated from the work published by the Rand Corporation of the United States in 1987. "They threw the report into archives. It came to me as anunclassified document and formed the basis for our approach," he told The Times of India.

already been done X 31 and X 37
