India resumed its HJT-36 Sitara extended flight training jet training program. According to "Nplus1" With reference to Flightglobal, the specialists of the Indian company Hindustan Aeronautics Limited conducted the first airplane flight after a three-year hiatus.

India resumed training aircraft development program HJT-36 Sitara




The development of Indian training aircraft was launched in 1997 year as part of the program to reduce the dependence of the Indian armed forces on imported weapons and military equipment. The first flight of the HJT-36 took place in the 2003 year, after which development continued, with varying success, until the 2014 year, when the experts revealed a significant overweight of the aircraft. Having failed to cope with the problem on its own, India turned to several foreign companies to assist in reducing the mass of the aircraft.

In the same year 2014, the Indian Ministry of Defense abandoned the project and announced a tender for the supply of foreign training aircraft. The project was stopped in the 2016 year after a test was discovered in the management of the aircraft.

In the resumed tests involved already modified aircraft. Changes were made to its design according to the results of extended testing of models in a wind tunnel.

The maximum take-off weight of the aircraft is 5400 kg. The wingspan of the 9,8 meter with the length of the aircraft in the 10,91 m. Engine: 1 × TRD "Saturn" AL-55I. Maximum thrust - 1 × 1760 kgf. The maximum speed is 750 km / h, the practical ceiling is 9000 m. The crew of the 2 person. It has five points for the suspension of weapons.

        Rather, for the warm places. Almost a quarter of a century to develop this, not to develop, and continue on ... They came to the design bureau directly from the institute, they built, they built, they built, they retired, but development still continues)

            Can you comment on the development of the "improved An-2" or some other long-term Russian construction, in this vein. I am sure that they will not agree with you.
            It turns out the Indians can, but we do not?
            Although ... let them suffer, if only they would not copy anything from us. Yes, and the Russian engine - there is a buzz.

          Well, the "tejas" was also built for years. Again, cutting budget attendants is a fascinating experience. Especially if nothing threatens you for it.

        So what are the wings and tail? There is even a different scheme with the 1 engine (at the Anchor 2).

        The project was to give Hawk (which is actively used in India, familiar to pilots and mechanics) - on a diet. That is, simpler, without any sighting stations and shock capabilities there. Cheaper. In general, for the primary training of pilots on jet technology. Now, Hawks and their ancient planes from 60's, which are falling apart, are using it.

        - Mountain shooter (Eugene)

        I agree with the first part. The engine is weak for a training aircraft with one engine, hence the problems with an advantage. The Americans are doing their training with an engine under 8000 kgf, and here only 1760 kgf. As the saying goes, feel the difference.

        On the second part, I do not agree that the Yak-130 is "significantly promising" in terms of a primary pilot training machine. The Yak-130 is difficult for primary training and technical operation, relatively expensive, uneconomical. the side of the low-speed, screw, piston YAK-10 - and this is in the age of jet aircraft ?!

        And the whole problem is that we, and Indians, do not have a turbojet engine of sufficient power of 6-8 thousand kgfs so that it can be put on a primary training training aircraft. This would ensure the relative cheapness of production, simplicity of design and maintenance, cost-effectiveness, which is what is needed for primary training courses.

      Is this the rival of the red CP-10?

        April 20 2019 12: 02
        In fact yes. Both projects were laid and buried in a coffin. But the Indians decided to dig out. CP-10 is not yet being dug up.

        All work on the CP-10 training aircraft is suspended due to lack of funds. This is reported by bmpd blog with a link to the web resource Mil.Press (Voennoe.RF).

        According to the publication, the promising training aircraft SR-10, which is created by the Design Bureau "Modern Aviation Technologies" (SAT), is already ready for serial production. The plane showed itself excellently in the last flight tests, but work on it was suspended due to lack of funds for mass production.

        As explained test pilot Viktor Korolev, demonstrator of the CP-10 trainer was tested "inside and out", up to a spin, from which it comes out remarkably well, without problems. He said that he had already completed 85 flights on the plane and gave the CP-10 a positive assessment, describing it as an aircraft that meets all the requirements for training pilots.. According to him, Smolensk Aviation Plant is ready to begin assembling the CP-10 immediately after receiving technical documentation for it.

        В Design Bureau "Modern Aviation Technologies" confirmed the lack of funds for further work on the SR-10, stating that "the Russian authorities do not allocate money" but they refused to tell the details.


        Maybe they will bring to the MAKS for their money and there they will bring Putin / Shoigu by the hand - they will put him in the cockpit, tell you what a cool and necessary aircraft you need, just push the bureaucracy a little.

          ========
          There are a lot of different opinions about SR-10! Here's an example of a skeptical assessment: (https://judgesuhov.livejournal.com/189133.html) ....
          The author expressed a number of doubts (and I agree with him!), Including: WHY do you need a CP-10 if you already have a very good TCB Yak-130 (besides having shock functions)?
          How is the "study desk ??" is it too bold? Isn't it better to use for primary education piston trainers (for reference: "... the cost of a flight hour of a turbojet trainer L-39 in the Russian Air Force is $ 800, and for single-engine piston training vehicles - $ 150-200. Fuel consumption per flight hour for an L-39 is 890 kg, for an aircraft with a piston engine - 50 kg ... "(http://airwar.ru/enc/other/su49.html)).
          There is one more question: Why did you need to develop a piston Yak-152 (also with a German engine) if there was already a very successful Su-49 (completely from domestic components)?
          Why is it necessary to produce "different types and herbs" of TCS? To complicate logistics and create a bunch of problems that require a lot of money to solve?
          I do not argue: maybe the SR-10 and actually the plane is not bad, maybe even a good one! But WHERE are its PRINCIPAL advantages? Why invest HUGE money in the deployment of mass production (and this oh how expensive!) to create another "gasket" between the primary training piston trainer and the Yak-130?
          Are we so RICH ??? No other MORE important topics?

            About the screw - so in fact it is needed. Not to fly over in XPlane11? The most basic skills to give. Plus theoretical loading through air clubs and private traders. But then again - there is something better a la C-172.

            As for the German engine - yes a problem, but there is no domestic one in terms of power, resource and economy. And laughed with Su-49. Sense corpse rotten stick poke?

            By the way, in addition to the Anchor - which is still designed and assembled on Irkut. Also, the licensed issue was established by the Austrian DA-42T at UZGA. And if initially it was only a training program for civilian pilots and a maximum for DOSAAF in the future (with greater localization). Now the planes are already arriving at the Balashov Center KVVAUL. They will train pilots IL-112В, Anov and other BTA aircraft.




            As for the CP-10. He's not needed. Or needed. No need xnumx aircraft in this niche. However, it is also expensive to carry out the main raid on expensive Anchors with 2 engines - having a high flight hour cost. CP-2 has one cheap engine that runs on donkey urine. But it is made on Ivchenko-Progress, in theory you can fix it on your own (now only repair and capital).

              =======
              As for the cost of a flight hour - here it is, YES! Single engine - as if more economical! True, this option is less RELIABLE! True, the cost of a flight hour - not just kerosene alone - you need to take into account the resource of the airframe and engine / engines and a bunch more ...
              Well, while there are still "Elki" - they will serve for some time!
              But with the CP-10 there are a lot of questions! Firstly, the car turned out to be "overweight" (for its size), and this despite the fact that composites are widely used there (with which I am also glad to have questions!) ... Well, the last (but probably the most important): Landing speed !!! On the SR-10, it is abnormally large - 240-260 km / h !!! For comparison, the Su-27 - only 225-240 km / h, and the Yak-130 - and in general 195!!!
              Conclusion: The machine is still RAW !!! Its still "to mind" to bring and bring!
              So we have in the "bottom line": The glider is "raw", there are no engines (it is necessary somewhere, somewhere, somehow to establish the production of analogs of "Ivchenkovsky", there is no normal design documentation either (they themselves admitted that they "riveted "in the garage on your knee!) ....
              So - "is it worth the candle and does the army really need it?" Maybe the Yak-152 "bundle" (or something like that) - the Yak-130 will ultimately be cheaper?

      I do not see adherents of Boeing and Bombardier. For Hindus, the production of national technology, albeit bad, is a matter of prestige.

      Strange Indian throwing, not amenable to analysis and logic, even Asian!
      Well, they do not have a predisposition to design work, so use strangers.
      After losing the competition (which won the Yak-130), the MiG-AT was offered for export for some time, but by 2010, having not found a single customer interested in finishing the machine, all work had stopped.

      Well, they would have bought with giblets and produced now, otherwise the issue of weight is still being solved.

      Russia would be nice to offer India the joint production of the Yak-130. So the plane would have turned out cheaper and it is better suited for training future pilots of the Su-30, Mig-29K and all others.
