    Not exactly. In recently concluded amphibious exercise, the same was fine tuned. Lets see what the ongoing TROPEX brings further to fore. Perhaps, a synergistic fielding of Mig-29s and Hawk?

    Piqua, Ohio, Jan. 30, 2017 -- Hartzell Propeller's four-blade lightweight aluminum propeller has been selected by Hindustan Aeronautics Ltd. (HAL) for its HTT-40 two-place turbine basic trainer aircraft.

    The new indigenous HTT-40 is designed and built by HAL under the country's Make In India initiative. The HTT-40 will replace the piston-powered HPT-32 Deepak trainer for the Indian Air Force.

    Hindustan Aeronautics is manufacturing three prototypes and two static test specimens with production activities to begin this year. Certification of the HTT-40 (Hindustan Turboprop Trainer-40) is expected in 2018. Flight testing will include 350 flights.

    "Hartzell Propeller is honored to add this new clean sheet aircraft from Hindustan Aeronautics to our growing list of aircraft from the world's leading manufacturers for both civilian and military applications," said Hartzell Propeller Executive Vice President JJ Frigge.

    The new HTT-40 is powered by the Honeywell TPE331-12B turboprop engine. Designed to meet pilot training requirements of the Indian Air Force, the new military aircraft also will have provisions for weaponization.

    The initial order from the Indian Air Force is for 68 aircraft. Total requirements could eventually rise to 120 of the basic turbine trainers for the Indian Air Force.

    A HTT-40 outfitted with Hartzell's four-blade lightweight aluminum prop will be exhibited at the HAL display at Aero India 2017, held Feb. 14-18 at Air Force Station, Yelahanka, Bengaluru. Hartzell Propeller will also have a booth with experts on hand to discuss propeller technical details.

    India broadens training role of PC-7 Mk II

    The Indian air force has been forced to commence intermediate stage II pilot training with the Pilatus PC-7 Mk II basic trainer aircraft (BTA), which also serves as its basic stage I trainer.

    “We understand that in the last couple of months, the IAF has thoroughly tested the aircraft with regard to their Stage II training syllabus requirements and determined that the PC-7 Mk II is very capable for deployment in an intermediate flying training role,” says Pilatus Aircraft executive Jim Roche in an email to Flightglobal.

    The PC-7 Mk II’s service entry in early 2013 ended the crisis stemming from the grounding of Hindustan Aeronautics’ HPT-32 ‘Deepak’ basic trainer on safety grounds.

    Prior to the induction of the PC-7, the air force undertook stage I and stage II training on Kiran jet trainers. In a reversal of roles, the PC-7 Mk II will now take-over the Kiran’s Stage II training role, as the service looks to keep the 1960s type in service till 2018.

    A number of challenges remain for the air force. Only 38 additional PC-7 Mk IIs are planned to be acquired from Pilatus, for a total of 113, instead of the 181 originally planned.

    Despite the delay in finalising the contract, the Swiss airframer’s now proven ability to deliver aircraft in short order, once a contract is inked, could be a source of comfort for the air force.

    At the beginning of the year, then HAL Chairman RK Tyagi told Flightglobal that its developmental basic trainer, the HTT40, would undertake its maiden flight before the end of the year. It would provide an indigenous solution to India’s basic trainer needs and include a weaponised variant. Developmental work on the type is now expected to be completed by 2018.

    Nonetheless, Pilatus remains confident of a firm order for 38 more PC-7 Mk IIs.

    “As has been reported by various IAF sources, discussions are continuing between Pilatus and the Indian air force regarding implementation of the option clause within the current contract,” says Roche.

    One advantage Pilatus has is a hot production line, which is producing five PC-7 Mk IIs for Malaysia and will produce nine PC-9Ms for Jordon. Deliveries for both run out to 2017.

    HAL, meanwhile, continues to have issues with its HJT-36 Sitara Intermediate Jet Trainer (IJT).

    Fifteen years of development have resulted in an aircraft that is overweight, has yet to clear spin trials and is powered by an NPO Saturn AL-55I engine with a Total Technical Life (TTL) of only 300 hours.

    The IAF has orders for 12 limited series production (LSP) aircraft, of which six have been produced so far, and orders for 73 series production aircraft. Nonetheless, the air force issued a request for information to global OEMs in February 2014 seeking an IJT. With the PC-7 Mk II fulfilling the stage II training role of the IJT, it is not clear if this RFI will lead to an RFP.

    HTT-40 2nd prototype to fly in March; innovations propel project

    By: Anantha Krishnan M7 Feb 2017, 03:22 pm

    Bengaluru: The second prototype (PT-2) of Basic Trainer Aircraft HTT-40 from Hindustan Aeronautics Ltd (HAL) is expected to have its maiden flight next month. During a visit to the facilities of Aircraft Research and Design Centre (ARDC), this Correspondent witnessed hectic activities as a prelude to its maiden flight.

    The PT-2 has almost completed the equipping process. It will be on static display area during Aero India 2017 with a fully functional cockpit and powered-on LRUs.


    “From removal of the fuselage to entire process of equipping is completed in one-and-a-half-months, which is a great achievement compared to any aerospace standards. We achieved it due to the modular technology being adopted for the project,” Prashant Singh Bhadoria, Deputy Project Manager, HTT-40, told Mathrubhumi.

    Started with HAL’s internal funding of Rs 500 crore, the HTT-40 project got the ahead for detailed design in August 2013. The detailed design was completed in 21 months (May 2015) and the BTA had its maiden flight in May 2016.

    Many improvisations on PT-1 already
    Suresh Kumar, Head of Aerodynamics Group and Project Manager of HTT-40 said the platform completed 32 flights, logging a cumulative of 25 hours, so far.
    “We did many gradual improvisations on PT-1 since its first flight. The fuel system has been converted into a fully pressurised one. Also the rudder was modified to address sensitivity issues. The ECS system was adapted to reduce the cockpit noise to optimum,” says Suresh, who has served HAL for over 30 years now.

    On PT-1 the ailerons have been fitted with balance tabs to give a more comfortable feel while doing lateral maneuvers like the 360 degree roll. The flap angles have been optimised for better take off and landing characteristics.

    On a specific query on the feedback the young HTT-40 team got from the pilots, Sanjiv Shukla, General Manager (ARDC) said the response has been positive.
    “The aircraft handling is very easy and the pilot-vehicle interface has been simplified for the trainer. The glass cockpit gives them a fighter-class effect and the display symbology is user-friendly,” says Shukla.
    Based on the pilot inputs, the rudder sensitivity and control harmony has been improvised

    “The glide ratio has already been achieved. The climb rates and the landing and take-off performances also have exceeded expectations,” says Shukla.

    The ARDC team is excited as PT-1 will be debuting at Aero India 2017, displaying some of its acrobatic maneuvers. The SOPs for both PT-1 and PT-2 are the same.

    Production team had a say from beginning

    On the new design and manufacturing philosophies adopted, D K Venkatesh, Director, (Engineering, R&D) said the entire project is based on digital mock up.

    “Our focus has been on rigorous simulation and ground testing in order to reduce the development time. The design for manufacturability theme has been the central focus. The production jigs have been set up using laser trackers with 50 microns accuracy. Metal tooling has been adapted for all sheet metal parts. The aircraft looming has been done on bench completely,” says Venkatesh.

    He said every drawing was production-vetted. “Any design and development has issues. We have to experience it. We have to overcome it. This young team has made all of us proud,” says Venkatesh.
    The project witnessed a mid-programme engine change issue, due to procurement challenges. The non participation of various suppliers due to the doubts surrounding HTT-40, had forced ARDC to absorb LRUs from existing projects.

    Team had tough time keeping the morale high

    “This, however, was a blessing in disguise as system commonality was helpful in cutting the development and procurement time lines. The project time lines were very challenging. The air surrounding the project during the launch phase too was not inspiring. It was difficult to keep the moral high but at theend of the day the company leadership ensured that the project stayed on track and achieved its milestones,” says Prashant, who recently bagged the Dr A P J Abdul Kalam Award instituted by AeSI national chapter.

    HAL now says that the next prototype (PT-3) will be design optimised with reduced weight. Also the PT-3 will be in line with the final SOP made along with the production agency. Plans are also afoot for weaponised variant (PT-4) in future, especially keeping the likely need of Indian Army. The target set for achieving certification is December 2018.

    HAL Chief Raju pats the young team
    On the tricky stall and spin tests for HTT-40, HAL says lessons from Intermediate Jet Trainer would come handy.
    With HTT-40 boasting of far advanced systems than those on Pilatus, currently being inducted in Indian Air Force, HAL says the indigenous content and design rights will go a long way in maintaining the aircraft for over the next three decades.

    HAL Chairman T Suvarna Raju refuses to take any credit for the success of HTT-40 project so far.
    “The boys slogged day in and out. They muted themselves from what the world thought about the project. This is again another management lesson we all can keep in mind. Always focus on your tasks. If you are sure you will achieve it. And, nothing else matters. HTT-40 tells you that story,” says Raju, who has been playing the role of a mentor for the team.

    Nobody believed in our abilities, but we did & proved: Team HTT-40

    By: Anantha Krishnan M
    8 Feb 2017, 04:12 pm

    The conference hall at Aircraft Research and Design Centre (ARDC) was packed to its capacity. In conversation with Mathrubhumi were some of the bright aerospace engineers and designers of Hindustan Aeronautics Ltd (HAL) sharing their story of struggle, sacrifice and success building their dream flying machine -- the Hindustan Turbo Trainer-40 (HTT-40).

    Amidst readying the HTT-40 PT-1 for its maiden sky party at the upcoming Aero India-17 and PT-2 for the static display, the team was enthusiastic in sharing some of the untold stories building the BTA (Basic Trainer Aircraft). Interestingly, the average age of HTT-40 team is only 35 years.


    Leading from the front was the passionate plane-maker in Prashant Singh Bhadoria, Deputy Project Manager of HTT-40. The promising youngster hailing from Nanded, was humble enough to take-off by saying but for the commitment shown by his team, HTT-40 wouldn’t have reached a stage it has jettisoned now.

    “The going was tough. Really tough. We had to motivate ourselves all the time. But, we had the full backing of our seniors and the top management. I think in military aviation the challenges are multitude. We have buried the past and believed in the future. The rest is history now,” says Prashant, whose aggression and passion were one notch up than Virat Kholi!

    Prashant-Suresh combo inspired the team

    Prashant represents the new face of HAL, who believes in their strengths rather than brooding over what a DPSU is not all about. Most importantly, it was evident that Team HTT-40 owned HAL. Rather, they said they are HAL.

    “Through this project we got challenges and opportunities in equal measure. The learning was phenomenal. The team work was outstanding. The sacrifices were innumerable. And the result, was priceless,” says Prashant, who hands over the baton to the rest of the team members.

    Prashant’s boss and HTT-40 Project Manager Suresh Kumar, who is also the Head of Aerodynamics Group, was another face of HAL that was refreshing. Suresh, the senior-most member, who was part of Kiran, IJT, Saras and Tejas projects, says his team emerged successfully from the jaws of defeat.

    “I will see HTT-40 in IAF Squadron before retirement. I too learned a lot being part of this young team. It not only knocked off some 10-15 years from my life, but gave a new perspective to missions. The team’s enthusiasm is infectious,” says Suresh.

    HTT-40 team members say the Suresh-Prashant combo set many benchmarks in project management.

    Sumesh, A S, Senior Manager with Structural Assembly while sharing the challenges of fuel tank assembly and engine installation, said the project demolished the disconnect between the designers and shop floor. “We bridged the gap and there was better synergy at all levels,” he adds.

    Pawan Gowra, Manager, Sheet Metal Shop, says concurrent manufacturing was the key to the mission.

    “It helped reducing time and we could assess the actual requirement at a faster pace,” says Pawan. “And, getting home-cooked food and sharing with all too helped to increase the bonding,” he adds.

    Only mission mattered to the team: Sanjiv Shukla

    Sanjiv Shukla, General Manager, ARDC, felt the young lot had no fear in taking on the challenges head on.

    “The HTT-40 team has set many new working philosophies that will be difficult to be broken now. They have showed all of us, mission mattered all the time,” says Shukla.

    Ajith K, Deputy Manager, Electrical Design, said he couldn’t believe when HTT-40 flew for the first time.

    “There was joy, satisfaction, relief and belief when our baby was flying,” he said. Ajith also narrated how the team members worked for 20 hours some days even dispelling fear of being hit by dengue, which is prevalent in Bengaluru.

    “Some of the team members were worried about mosquito bites. And, we told them mosquitoes that bite in the night won’t spread dengue,” Ajith said, with team bursting into laughter.

    The team played a rare video of HAL Chairman T Suvarna Raju addressing them from with the HTT-40 cockpit late night. “It was truly inspiring,” adds Ajith.

    If your aircraft is talking, then you don’t have to talk: Prashant

    Prashant chips in again saying aggression was the key while taking tough decisions.

    “You have to be ready to take risks. We had to prove our detractors wrong. If your aircraft is talking, then you don’t have to talk. We are now very focused on the spin and stall trials as well,” says Prashant.

    Chandrashekar V, Senior Manager, Aerodynamics, says they could predict the thrust and drag characteristics of the aircraft perfectly before the first flight.

    “We had detailed CFD (Computational Fluid Dynamics) studies. We were able accurately assess many results in advance,” he says.

    Jeevan says unique procurement methods sticking to the rules helped the project, while Gopalakrishnan terms the HTT-40 experience as one of the most inspiring lessons in his life.

    Failure is important tool for designer: Venkatesh

    D K Venkatesh, Director, (Engineering, R&D), HAL, predicts the need for HTT-40s in large numbers in future.

    “I always told the boys not to reinvent, instead synergise. Failure is the most important tool for the designer. This project faced many challenges and yet we came out with flying colours,” says Venkatesh.

    HAL Chairman T Suvarna Raju, who often drove to the shop floor even on Sundays, without any prior notice, says he was moved by the commitment and dedication shown by the HTT-40 team.

    “The brave lot, they are. They never got tired. It will be their Aero India this time. And, we are all proud of the HTT-40 team,” says Raju.
