Defence sources said the HSTDV, designed to cruise at Mach 6 speed with the scramjet engine, was supposed to “fire and fly on its own” after being carried to an altitude of around 30-40 km by the solid rocket motor of an Agni-I ballistic missile in the test. “But the Agni-I booster went into an uncontrolled mode after the launch and could not achieve the desired altitude…So, the entire test flopped,” said a source.

The cruise vehicle (HSTDV) was supposed to be ejected out of the launch vehicle (Agni-I) and be propelled by the scramjet engine after it auto-ignited at the required altitude but it failed to do so during the test. The test was considered critical for the development of a hypersonic (over Mach 5 speeds) cruise missile system in the future.

If you don't succeed at once try again.

We can learn much more from our failures. We should constantly strive to fix small issues and move forward and one day we will taste success.

Nazi Germany, USA, USSR all great powers tried and failed and again tried until they succeeded.
Try-Fail-Try, is the mantra of success.


For me this test itself is a big success because with this attempt India is trying to reach the peak of the mountain, the cutting edge of technology.


My respect to all India scientists who dared to dream this big.

The test has been a success according to Hemant Kumar Rout.

http://www.newindianexpress.com/nat...-becomes-second-country-to-do-so-1989261.html

BHUBANESWAR: In a path-breaking attempt, India on Wednesday conducted first test of Hypersonic Technology Demonstrator Vehicle (HTDV) from a defence test facility off Odisha coast setting the perfect ground for the development of long-range cruise missiles.

Mounted on an Agni series missile, defence sources said, the technology demonstrator vehicle was launched in autonomous mode from the world-class missile complex located at Kalam Island at about 11.25 am.


Powered by scramjet engine it can cruise at Mach 6 and have multiple civilian applications, including the launch of satellites at low cost besides long-range cruise missiles.

Defence authorities claimed that the vehicle was launched successfully and India became second country in the world after the US to have developed the hypersonic technology.

“The maiden launch of the technology demonstrator vehicle has been successful. Data generated during the mission are being analysed. We are trying to achieve what no country has attained. The vehicle will help prove a number of technologies for futuristic missions,” an official confirmed ‘The New Indian Express’ over the phone from New Delhi.

The six-meter long air vehicle with a launch weight of around one tonne features a flattened octagonal cross-section with wings on mid-body and tail fins. The scramjet engine is placed at the mid-body while the portion towards the tail serves as exhaust nozzle. In between, there is a rectangular component of about
12-foot for air intake.

The technology was under development for the last over a decade as part of an ambitious plan for the hypersonic cruise missile. Though Indian missile arsenal boasts BrahMos cruise system developed jointly with Russia, it is supersonic in nature and can travel at a speed of Mach 2.8. A long-range missile with
hypersonic technology could be a strategic killer.

The hydrocarbon-fuelled scramjet engine developed by Indian Space Research Organisation (ISRO) had already completed ground-based tests using moderate size hypersonic wind tunnel and conventional shock tunnel.

After a couple of laboratory tests, the initial flight of the vehicle was aimed at validating the aerodynamics and aero-thermodynamics of the air vehicle and performance of the scramjet engine along with the audience system. The mission involved launching of the hypersonic air-breathing cruise vehicle with the help of a rocket at an altitude of 25 km.

While Chairman of Defence Research and Development Organisation (DRDO) G Satheesh Reddy monitored pre-mission activities, Defence Minister Rajnath Singh and Defence Secretary Sanjay Mitra reportedly witnessed the test.

And our Shook Law ji says the test was a complete success.

This first test was aimed at demonstrating the performance of the modified Agni 1 booster, guidance systems and the Aero thermodynamics of the HSTDV. There wasn't any ignition in the scramjet in this first test and therefore there wasn't any hypersonic flight.

This test was meant to validate some technologies which are crucial to achieving hypersonic flight.



The Defence Research and Development Organisation (DRDO) took a step towards the coveted technological goal of achieving hypersonic flight with the launch of a technology validation mission on Wednesday.

“DRDO today launched a Technology Demonstrator Vehicle to prove a number of critical technologies for future missions from Dr Abdul Kalam Island off the coast of Odisha… The data has been collected and will be analysed to validate the critical technologies”, announced the DRDO.

Rockets have long travelled at hypersonic speeds, but they have the advantage of carrying their own oxygen along with their fuel. Achieving hypersonic flight with an air-breathing engine is the greater challenge. Only Americans, French, Chinese and Australians have managed 10-second hypersonic flights. The DRDO has targeted a 20-second flight.

Hypersonic flight involves travelling at speeds above Mach 5, or 1,500 metres/second. An airliner travelling at hypersonic speed would reach from New York to Tokyo in a couple of hours.

Hypersonic flight also achieves military objectives, such as carrying larger payloads than conventional rockets. Since a hypersonic missile does not have to carry oxygen – it uses the oxygen freely available in the ambient air – that allows it to save weight, and carry a larger payload. This is called having a larger “payload fraction”.

The key challenge in hypersonic flight is to develop an engine that can remain alight even when the air it breathes is being rammed the combustion chamber at a velocity of 6.5 Mach. That is why it is called a “supersonic combustion ramjet”, or “scramjet” engine.

While the Wednesday mission was not intended to achieve hypersonic flight, it had the aim of validating key technologies essential for hypersonic flight.

Amongst these technologies was a launch vehicle – a modified Agni-1 missile to launch the technology demonstrator vehicle and boost its velocity – the guidance systems, and heat shields for protection during re-entry.

In the actual hypersonic flight demonstration, which the DRDO intends to carry out within a year, the Agni-1 booster would release the hypersonic vehicle after re-entry, which would then ignite its kerosene fuelled scramjet engine and fly for a significant duration of time.

A key challenge is developing the super-materials that can withstand the extreme temperatures and pressures of hypersonic combustion. This includes Niobium alloy, Hafnium and Nickel-based superalloys.

Last month, speaking at the Institute for Defence Studies and Analyses, the DRDO chairman mentioned hypersonics as one of the key areas for future wars.

“We are confident of achieving hypersonic flight for a significant period of time within the next four years”, states a senior DRDO manager.

Most important take away is that they have moved from theory to practice. It is only a matter of time now. They are confident enough to actually test their device despite great expense and stake.

Word of DRDO is enough. Defense minister and defense secretary both were present for test. CAG will have a report on it. There is no scope of denial or lies in official DRDO release.

India’s DRDO Scrams Into Military Hypersonic Club With Successful HSTDV Test
HSTDV Airframe


India has entered the military-application oriented powered hypersonic club with the Defence Research & Development Organization (DRDO) successfully conducting a test of the scramjet -powered Hypersonic Technology Demonstrator Vehicle (HSTDV) earlier today. According to DRDO, the test has achieved all the objectives that had been set for it in terms of aerodynamic parameters. As such, this test paves the way for the credible development of future scramjet-powered hypersonic delivery vectors by India.

The HSTDV flight test took place at 1103 hours this morning from the APJ Abdul Kalam Launch Complex at Wheeler Island, off the coast of Indian state of Odisha. Till recently, the HSTDV programme which is led by the Defence Research & Development Laboratory (DRDL) of DRDO had been one of those long running frontier military projects that seemed just on the cusp of yielding something, only to have deadlines pushed further away. This, of course, was not particularly surprising given the complexity of the technology involved whether it be in terms of intake design or choice of fuel.

Nevertheless, today’s HSTDV test has put all that behind and according to DRDO Chairman Dr Sateesh Reddy, today’s test was an ‘unqualified success’. Speaking to Delhi Defence Review, he further maintains that this is a ‘major technological breakthrough for India that will the pave the way for the development of many more hypersonic vehicles in the coming years’. Dr Reddy sees a full-blown scramjet-powered hypersonic vehicle for payload delivery being ready within the next 5 years.

This morning’s test saw the scramjet-powered HSTDV test-article sustain a speed of Mach 6 (i.e. almost 2km/s) in the course of its 22-24 second flight at an altitude of 30 km. Kerosene was the fuel used by the scramjet combustor, although work on the use of JP-5 has also been underway for some time now. An Agni-I booster was used to loft the HSTDV to an altitude of 30 km and impart the necessary momentum for the scramjet combustor to attain ignition.
Graphic: A simplification of the mission profile of today’s test. The flight duration for today’s HSTDV test-article was greater than 20 seconds, however.

As an aside, the Agni-I medium range ballistic missile’s booster has a diameter of 1.0 metre and is solid-fuelled using a composite propellant.

All parameters related to the entire mission profile, including the performance of the scramjet engine was monitored by multiple tracking radars, electro-optical systems and telemetry Stations. A ship was also deployed in the Bay of Bengal to monitor the performance of the cruise phase of the HSTDV and DRDO seems very happy with the test results.

It is understood that the HSTDV test-article was released at a speed exceeding Mach 5. The release of the HSTDV first involved the separation of the aerodynamic heat-shields of the launch vehicle, followed by the injection of the test-article into the atmosphere. Importantly, the air-intake of the HSTDV test-article opened as planned once it left the launch vehicle.

Now, though 22 plus seconds of scramjet combustion at altitude is a noteworthy achievement for an initial flight, the objective is to increase the duration of the same to a couple of hundred seconds in the future while sustaining a speed in excess of Mach 6. For the time being, DRDO believes that the successful execution of critical test events like fuel injection and auto ignition of the scramjet has demonstrated a certain technological maturity. Indeed, critical technologies such as aerodynamic configuration for hypersonic maneuvers, use of scramjet propulsion for ignition and sustained combustion at hypersonic flow, thermo-structural characterisation of high temperature materials and separation mechanism at hypersonic velocities have all been validated in today’s test.

According to DRDO, telemetry data indicated that the scramjet engine worked at high dynamic pressure and at very high temperature, as was desired. This test no doubt augurs well for the development of air-breathing in technologies in India.
