    India Conducts First Test Of Hypersonic Air Vehicle, Questions Over Result


    [​IMG]

    An Indian hypersonic weapon technology demonstrator was flight tested for the first time today by the country’s Defence Research & Development Organisation (DRDO), though it is understood that the test was not completed successfully. In the works since the turn of the millenium, the vehicle was tested this morning off India’s east coast. The DRDO issued a short statement confirming the test:

    Defence Research and Development Organisation (DRDO) Today launched a Technology Demonstrator Vehicle to prove a number of critical technologies for futuristic missions from Dr Abdul Kalam Island off the coast of Odisha. The missile was successfully launched at 1127 Hours. Various radars, telemetry stations and electro optical tracking sensors tracked the vehicle through its course. The data has been collected and will be analysed to validate the critical technologies. — DRDO STATEMENT

    The statement, typically vague, doesn’t mention the status of the test, leading to speculation over whether it successfully met all test points, or whether it was aborted per force. Top sources tell Livefist that the Agni-I ballistic carrier vehicle on which the HSTDV was to receive its altitude boost, didn’t complete the mission, therefore likely precluding the flight of the hypersonic demonstrator itself.

    How the HSTDV was launched, carried on an Agni-I ballistic missile

    The DRDO and MoD haven’t responded to questions about the status of the carrier and demonstrator vehicle’s performance. Livefist will update this report if and when they respond and provide official detail. Separately, the Chief Minister of Odisha Navin Patnaik and Union Minister Dharmendra Pradhan both, congratulated the DRDO for the flight on Twitter.

    Whether or not the test was ‘successful’ in terms of meeting all expectations, it must be said that flight testing a complex air vehicle for the first time is fraught with complexity and risk. While the precise details of how the launch platform and HSTDV performed (or if the latter achieved flight at all) are not known at this time, the HSTDV team will undoubtedly be looking to fix what went wrong. One scenario suggests that the Agni-I missile carrier malfunctioned. If that is the case, it doesn’t strictly throw a cloud over the HSTDV itself, but does raise questions over an inducted weapon system. Overall, an advanced technology aeronautical test of this kind even achieving flight-worthy status is a major achievement. None of this of course precludes the difficult questions that will face the test team now as they align to fix problems for the next attempt.

    The DRDO statement also doesn’t reveal what speeds were being aimed to be achieved even though official data (see below) on the project mentions speeds of between 2-8 Mach, a wide margin. That being said, the test today is a small first step but an important one in what has been a long-standing propulsion project — one that the DRDO has kept necessarily under wraps and believes will be a gamechanger. The purpose has been to develop and then flight-prove a fully indigenous scramjet engine using kerosene fuel (the DRDO also recently tested a solid fuel ducted ramjet system).

    The HSTDV is a curious project — there is no specific requirement from the military for such a capability, especially since the DRDO still depends on Russia for the ramjet engine that powers the joint BrahMos supersonic cruise missile. With a squeezed development budget, at least one former military chief that Livefist spoke to wondered whether the DRDO had “fulfilled basic needs of the forces to justify the luxury of such high-end research”. These are questions that have always — and must always — buffet the DRDO’s choices. The tilting balance between baseline needs of the military and ambitious futuristic research projects have always rankled.

    The long term vision is for the hypersonic propulsion technologies to fuel platforms for extended air defence, global targeting and surveillance/reconnaissance. In 2010, right around the time images first emerged of the HSTDV’s wind tunnel model, Livefist also accessed official literature on the program, providing the first formal schematics and data on the vehicle:

    LoL!! How many countries succeeded in their first attempt, particularly in complex tech like Hypersonic missiles
    Yeah, we've had successes in the past in the very first attempt and we tried and succeded in cases like Nirbhay cruise missile. Also, the article says unconfirmed reports which indicates the author knows jack-shite and is just farting from his mouth

    Nevertheless, even if this is a failure...we'd continue to identify the faults and develop a fully functional missile in due time

    DRDO clarifies it was a test of skip glide capability of the tech demo.
    Full test is still few months away.

    Sir they have every right to do just that. Based on their history with some of the other so called "indigenous" projects, they will try for about 10 years and then seek outside help to be successful.
    Anyway, thora sa khush hone ka haq tau den. Aik bezarar sa 'lol'

    Ok. Good luck.

    Indians like to plan a project that is beyond their technical ability and request continuous budget support. That is how scientists and engineers make money in India. Afterward, they will declare partial success and request for help. Thats how they roll.

    No wonder these guys are not working for Dell. They have a scheme ripping India off.

    We might've delayed some projects but there are certain platforms where in excelled in. For instance all our naval platforms from Destroyers, Frigates, Corvettes, OPVs, Subs have been built indigenously and so are our rotary winged aircrafts. We've been doing well in missile tech as well from ICBMs, sub-launched missiles like K-4 & K-15 to Astra AA along with air-defence systems like Akash SAM, AAD, PAD etc and JV with Israel regarding Barak LR-SAM

    We successfully tested the rail gun concept as well, not at the scale of achieving large scale destruction but a test with a bigger projectile is scheduled to take place this year. Regarding Brahmos, we replaced the seeker with an indigenous one making the Indian components share even higher and the only system that is Russian is the propulsion motor. We can replace that as well but since it's a JV with Russia, we intend to keep that one. Even though a hypersonic version of Brahmos is being developed by India & Russia, MoD wanted a completely indigenous version separate from the Brahmos project so that we reduce our reliability on foreign sourced components

    Cant agree more. They have progressed very well economically which is more to do with political stability than anything else. But all this talk of technologically being at par with the developed countries is laughable really.
    There is absolutely nothing wrong with trying and failing. That is how everyone else has progressed (albeit with a much lower failure rate). But this nonsense about having somehow achieved technological , academic, industrial parity overnight with the likes of US and Russia and China is just that. ...Non sense. The hubris is nauseating.

    And they have no sense of humour

    Good for you sir. Although am not that convinced about the technological prowess of India in all that projects as you still import critical technologies.

    By the way had always admired India the way it protected and preserved its democratic values throughout the cold war when uncle sam was busy helping every other country that didnt tow its line with coups and regime changes. That untill Modi happened. Seems you people are going the exact same way we had gone 40 years ago. Disappointing really but that is just my view

    No one here is saying India has the technological prowess on par with US, Russia or China. I openly admit India is far behind in terms of defence tech and research. Even though my countrymen mock China for reverse-engineering Russian tech, they reached a level where they're able to develop new tech from what they've learned. Years of bad governance, mismanagement of projects & funds, sucking up to foreign firms in favor of commissions & kickbacks which still exists resulted in where we are now. Our PSUs have sucked big time with firms like HAL, OFBs and even DRDO recruiting engineers & scientists based on reservations and favoring a particular sect of people who are incompetent AF. I interned in a non-defence PSU in central India and all the employees did was to drink gallons of tea and chat about every useless topic that ever exists.

    Thankfully, the situation is improving with MoD allowing private firms to participate in defence contracts and removing the unilateral advantage that PSUs had all this while. No wonder companies like Tata & Reliance partnered with LM, Boeing, Airbus, Sikorsky etc and building top end tech like the fuselages of Apache, Chinook, US presidential choppers, S-92 and many more by setting up defence manufacturing hubs in Hyderabad, Bangalore & Pune primarily.

    There's still a lot of changes that are to take place for our organizations to come up to speed and be on par with Russia & China. Accountability of utilization of funds is another important factor and also the % allocated to research which is very less in India
