    Read the thread from first page, before getting to conclusion ..

    The thread contain various other programs which were worth mentioning and IAF`s procurement policy specially accruing this BTA, More importantly this is not about PSU or Private but Indian ..

    Keep out other topics which are not about HTT-40 ..

    The HTT-40 literally has twice the horsepower of the PC-7. Like the PC-21 it can be used as a replacement for intermediate jet trainers. PC-7 is for learning flight basics. Good news is HAL has a bunch of experience from the HPT-32 so those design flaws were taken care of in the initial phases. HTT-40 is fine for basic training flights but it will be interesting to see if her flight envelop can replace the need for intermediate jet trainers and save IAF millions in cost per flight hour. Basic flight training can be done from simulators, you need a turboprop with some horsepower to transition into jets, just chugging along with low powered props doesn't get the job done.

    HTT-40 has been fitted and flown with a parachute gantry. Actual stall/spin testing to commence shortly.

    Why we need parachute for such low speed plane.

    The truss installation has been a significantly complicated process for the designers and engineers as it had to be installed at the rear part of the aircraft extending it away from the rudder. https://t.co/tMReLM3iDq

    Propelled by HAL’s young blood, HTT-40 ready for critical stall & spin tests

    Bengaluru: Two prototypes (PT-1 & PT-2) of the Basic Trainer Aircraft HTT-40 from the hangars of Hindustan Aeronautics Ltd (HAL) are ready for the crucial stall and spin tests.

    Since Aero India 2017, the young team from HAL’s Aircraft Research and Design Centre (ARDC) were reading both platforms for the stall and spin tests, which had given enough nightmares for the erstwhile HJT-36 (Sitara) project.

    Mathrubhumi can now confirm that the design and manufacture of the anti-spin gantry truss has been completed and they have been already integrated on to both prototypes.

    The aircraft has already started the flight-testing with the spin gantry and will start the stall and spin tests in shortly.

    The truss installation has been a significantly complicated process for the designers and engineers as it had to be installed at the rear part of the aircraft extending it away from the rudder. This has been done ensuring that the rudder doesn’t get obstructed as the parachute is being deployed.

    The ASPS (anti-spin parachute system) is a mandatory requirement for undertaking spin tests. The ASPS will be used to arrest the spin manoeuvre, if the aircraft fails to control the spin.

    The spin gantry has been imported from American firm Airborne Systems. Insiders say that it has been delivered in a record time of three months as against a cycle time of three years which was taken for earlier projects.

    Wind tunnel testing results encouraging

    The truss structure is a complicated welded entity, which has tested the nerves of the ARDC team.

    “We have done enough wind tunnel model testing and the results are encouraging. The stall and spin characteristics results have further boosted the morale of the team,” says an official.

    The designers have been taking an extremely cautious approach keeping in mind the challenges it had thrown for the HJT-36 programme.

    The ARDC team has done extensive simulation analyses before arriving at the current configuration.

    Both prototypes have completed more than 120 flights, ticking off other test points ahead of the ultimate test.

    The certifying agency CEMILAC, which is doubling up as a co-designer in the HTT-40 project, seems to be having a positive bearing on the project. The target set for achieving certification is December 2018.

    Interestingly, HAL’s head T S Raju have been playing the mentor’s role for the team, and letting them know on many occasions that the HTT-40 is a project owned by the youngsters of the company.

    Parrikar’s backing inspired ARDC team

    Former Defence Minister Manohar Parrikar is a huge fan of the HTT-40 project, and has taken immense interest in patting the young team from time to time.

    Parrikar had expressed confidence during the first official flight of PT-1 in June 2016 that the young team would deliver an aircraft as per the needs of the user.

    With his successor Nirmala Seetharaman expected to visit HAL and DRDO labs in Bengaluru shortly, the ARDC team is leaving no stone unturned to catch the attention of the ‘minister on the move.’

    The HTT-40 had stolen the limelight during Aero India 2017 with its 36-year-old Deputy Project Manager Prashant Singh Bhadoria and his team being the most-sought-after-souls at the show.

    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 PT-I had its maiden flight (unofficial) in May 2016 and PT-2 in May 2017.

    Another prototype (PT-3) with optimised design\ reduced weight and a weaponised variant (PT-4) are expected to fly out from the ARDC hangars in future.

    Hopefully IAF/Govt. does not kill this project for "Strategic partnership" with Pilatus built by Indian company :)

    Is there any ETA for the PT-4 the weaponised version? I hope it can be used for ground support in anti naxals and anti terrorism operations.

    Old news - but relevant..seems like this got burried.
    https://www.ndtv.com/india-news/pil...-dealers-papers-raise-questions-1414951?amp=1

    Pilatus Aircraft Deal Under Scanner As Arms Dealer's Papers Raise Questions

    "Story Highlights
    Arms dealer Sanjay Bhandari is being probed for alleged financial crimes
    His company received 7,50,000 Swiss Francs from Pilatus in 2010: Sources
    In 2012, government signed Rs 2,896 crore deal with Pilatus for 75 planes"
    "Mr Bhandari is already being investigated for allegedly buying a benami or proxy-owned house for Robert Vadra in London. Now, investigators are now probing what kind of services his company, the Offset India Solution Private Limited, had provided to Swiss aircraft major Pilatus."

    "Defence Minister Manohar Parrikar had earlier indicated his reservation about the deal."

    "I will investigate, but will not stop flying the aircraft," Mr Parrikar had added.

    Wonder why BJP has not done anything about this yet.

    Pilatus PC7 Mk2 cannot be weaponised as per our deal. If IAF does not want HTT40, it can be given to Army Aviation wing for light attack, CAS and also to CRPF, BSF, etc,. for COIN operations.

    Parrikar initially cleared the order of 38 more PC7s, but neither they were finally contracted, nor did we extended the maintenance contract for the first 75. The CBI investigations are on going.

    Is there some kind of financial trouble brewing at HAL? First the news was the backlog was at it's lowest levels, then the Drhuv was being sent to private production and now HAL doesn't have the money to pay Dassault for M2000 equipment maintenance and is demanding IAF pay for it when they are under contract to do it.

    Not financially since the helicopter, trainer and LCA orders are firm. But they have to adjust to the political shift of the NDA government, that at least appears to favour private Indian industry, so HAL needs to be more competitive for the future. Outsourcing production part is one of the obvious goals, selling shares of the company (around 10%) to be less dependent on government funding, is another one and there are long term goals to expand in other areas of the aviation field as well.
    However, they got several blows in the last few years too, the failure of IJT, MTA cancellation, Avro replacement shifted to private industry and the delays of FGFA, which now threatens the MKI production facilities, that initially was meant to directly switch to FGFA.

    But at the end of the day, they will remain under government control and dependent on them.
