    Boost to Make in India: HAL Rolls-out HTT-40 Prototype

    Bengaluru, February 2, 2016:

    [​IMG]

    HAL has rolled-out the first prototype of HTT-40 with the aircraft sporting all the aircraft lights and powered on cockpit. Mr. T. Suvarna Raju, CMD, HAL said that the HTT-40 prototype efforts symbolizes the renewed and revitalized proactive approach at HAL. “It is important that all of us work towards meeting deadlines by overcoming challenges to meet the expectations at various levels. The project has managed to steer through the initial headwinds and now is going full throttle. There are plans to weaponize and optimize HTT-40 aircraft”, he added.

    The roll-out of prototype took place recently from the equipping facility at Aircraft Research and Design Centre (ARDC) hangar through a remotely operated minicar. HAL Board members were present along with members from Flight Operations, IAF-IPMT(integrated project management team) headed by Air Marshal Rajesh Kumar, Regional Center for Military Airworthiness (RCMA) and Regional Director of Quality Assurance (RDQA). The team composition of HTT-40 is the youngest ever on any prototype programs in HAL.

    The aircraft is now ready for undertaking ground runs and taxi trials to be followed by its maiden flight. The ground runs will be conducted with the assistance from the engine OEM at ARDC itself.

    The HTT-40 design was adapted to a final decision on engine selection in May 2015 and the first prototype manufacturing is completed followed by this roll out.

    In November 2015, the Indian Air Force had issued task directive for the Design and Development of HTT-40.

    ARDC also touts HTT 40 as the first ever prototype to be manufactured completely based on a digital mock-up and also by using laser tracked jigs and metal tooling at proto phase itself. Also, the Division has sought active participation of Aircraft Division, Bengaluru which has been identified as the production agency for HTT- 40. Out of the 90 LRUs on HTT-40, 70 systems are sourced from sister Divisions of HAL which include HAL Lucknow, HAL Hyderabad and HAL Korwa(U.P). The Aero Engine Research & Design Centre (AERDC), Engine Division and HAL Kanpur are participating on the engine integration aspects.

    About HTT-40:

    Hindustan Turboprop Trainer (HTT-40) is a tandem seat trainer aircraft being developed at HAL for the first stage training of rookie pilots. With advanced features like zero-zero ejection seats and multi-function displays, it can also be adapted as a light attack aircraft. Its role includes basic flying training, aerobatics, instrument flying, navigation, night flying, close formation etc.

    Indigenous Basic Trainer Aircraft First Flight Likely in March


    NEW DELHI: India's home grown basic trainer aircraft, the HTT 40 is set for a first flight by the end of March as work on the project has accelerated after a firm push by Defence Minister Manohar Parrikar
    . The aircraft, the prototype of which was rolled out in January, is to be used for the first stage training for all flying cadets of the three services.

    Officials associated with the project have told ET that the Hindustan Aeronautics Limited (HAL) basic trainer has started the ground runs phase of the developmental process and that a first flight could take place as early as March. "We have been running Engine Ground Runs and are looking for a first flight within the next 4-6 weeks. This would be a major landmark for the project," a senior official said.

    While the HTT 40 program was almost junked by the last government, ET has learnt that Parrikar has taken up a strong case to develop the trainer under the Make in India initiative and the defence ministry has already committed to purchasing at least 70 aircraft.
    Sources say that initial studies have shown that the aircraft could have export potential as well in the future and that the total Indian requirement itself could exceed 200. India currently relies on the Pilatus PC7 Mk2 trainer that was bought under an emergency purchase from Switzerland after the older fleet of HPT 32 trainers were grounded.

    In the first phase, the trainer will be used for first stage flying but HAL also has plans to develop a weaponized version of the aircraft at a later stage to meet potential requirements in non-conventional operations.

    The development process of the trainer has involved the generation of at least 4350 detailed drawings, 1200 documents and extensive wind tunnel tests. While the ground tests and engine integration has been completed, the aircraft is now going through ground runs that will be followed by the first flight.

    At present, the air force relies of three aircraft for coaching pilots - a basic trainer, the intermediate jet trainer and an advanced training aircraft. However, with the Kiran Mk II intermediate trainer fleet already on retirement phase and an intermediate jet trainer not available, the IAF has rejigged its program in a three stage, two aircraft plan.
    At the higher end the Hawk advanced trainer is available in adequate numbers but there is a shortage of basic trainers. The air force had purchased 75 of the Pilatus PC 7 trainers in May 2012 but the requirement is for over 106 more planes. While a plan is being pursued to purchase another 38 of the PC 7s from Pilatus, the contract is still stuck on pricing issues.
    In March 2015, the defence ministry scrapped an air force plan to order close to a hundred more PC 7s in favour of the indigenous HTT40 project.

    It has been controversial trainer. IAF had rejected it a few years back, siting technical flaws. It has to prove itself before its criticism is watered down.

    Naah dont apologize!... HTT 40 will have to prove itself. In IJT case too, HAL patted its back tooearly, for realizing a prototype from drawing board within a year.. and we know how it went...

    Wonder why HAL did not take help of NAL/ADA in this case

    Will HAL replace the Rolls Royce engine with the HAL developed and Manufactured Hindustan turboprop engine? It can be used in HTT 40 and IJT too ..

    NAK browne had given bogus info to defence minister to favour pilatus including guaranteeing that Pilatus will be cheaper to buy etc etc. But as it turns out, Pilatus is more expensive

    HTT 40 has been ordered by IAF & IN in the past ..... does that order still stands ?

    PC 7 is being used by IAF .... any comparison between PC 7 & HTT 40 .??

    HAL, DRDO, ADA have money to burn on laboratory prototypes and technology-demonstrators. It's unfortunate that it comes way too late (still it's nowhere near ready though). Fact of the matter is that with the PC-7 already inducted and more coming, there is simply no requirement in IAF anymore for another type of Basic Turboprop-Trainer (BTT). This HTT-40 would meet the same fate as the NAL Saras.

    Unless ofcourse if the agencies wise up a bit and seek export customers. But which country would be ready to invest time & money in a yet-to-be-proven BTT from a not-so-famous manufacturer? Remains to be seen.

    You do forget that now, even Navy and Army are considering having more infrastructure for flying.
    It is not too late, Three are already irregularities found in PC-7 deal,

    More requirement of the same kind (basic turboprop trainer) equals more orders of the same kind (PC-7). If the IAF is going for PC-7, then Navy will also go for the PC-7 because it always seeks commonality as a way of reducing cost as well as saving time.

    In the same way how IAF orders of BAE Hawk made the Navy also acquire the same bird.

    AAC doesn't fly many fixed-wings so they don't seem to have much of a market there. Even if they do, it'll be more PC-7s.

    If there are irregularities, the agencies will take care of it. Investigations will be sought and the guilty will be held. But no-one is looking to jeopardize the forces' capabilities for the sake of suspicion. Already the fiasco of the AW-101 VVIP deal has made an example and the forces AND the MoD will seek to avoid repeating of such incidents.

    Problem comes when people HOPE & COUNT ON deals getting stalled or cancelled...just so that a different aircraft (of their preference) gets the contract. That's just utter baloney.

    This will go the LCA way, the IAF will be reluctant initially later will accept praising an indigenous aircraft. Another saga part two before IJT and AMCA.

    No it won't. Neither will Navy....because the PC-7 is already inducted & fulfilling all Basic trainer roles in IAF, and IN will also select the same aircraft for it's BTT role when needed.

    The HTT-40 simply has no viable customers within India.

    If they want to turn it into a production aircraft, they'll have to look for buyers on the international market.
