    1. Draft PSQR compliance document sent to Air Hq. PSQR is finalized by Air Hq on 10th June, 2016.
    2. A lead-in project for “Design of GHATAK and Development of Critical Advanced Technologies for GHATAK and AMCA” is sanctioned for Rs.231.00 crores on 13th May 2016. Major technologies to be developed under this lead-in project are broadly classified under five technology areas viz.,

    Captureg.JPG

    (a) Model Based Systems Engineering (MBSE)
    (b) Autonomous flight control technologies
    (c) Aerodynamics and Propulsion technologies
    (d) Stealth computations, measurements, structures & materials
    (e) Technologies for GHATAK systems

    Focused advanced design tools for Multi- Disciplinary Optimization (MDO) using a HPC computing infrastructure will be developed for flying wing configuration improvement studies. Levels of flight
    autonomy will be increased through testing of ATOL and FADS on LCA and scaled autonomous flight demonstration of GHATAK. Through 1/6th scaled flight model of GHATAK, technologies like control law for flying wing, fluidic thrust vectoring and stealth materials will be tested and evaluated in a cost effective way.
    TRLs of critical advanced technologies like conformal antenna, SAR, EO/IR, FADS shall be improved and adapted for GHATAK. Full scale GHATAK RCS model will be tested at ORANGE facility to evaluate RCS hot spots and to enable RCS reduction. Weapon release studies and deployment mechanism would be studied
    using high fidelity unsteady CFD modeling of URANS. Effective ejector based cooling mechanism for embedded high aspect ratio nozzle will be combined with ECS cooling requirements along with compact heat
    exchangers.

    Financial Aspect:
    a. Commitments for 2016-17 : Rs.43.00 Cr.
    b. Cash Out Flow for 2016-17 :Rs.30.00 Cr.
    c. Planned Commitments for 2017-18 : Rs. 82.00 Cr.

    3. Several Advanced Technology proposals for GHATAK and AMCA from DRDO Labs is received and reviewed. First Review meeting for 16 Advanced Technology proposals r e c e i v e d f r o m D R D O i s
    completed on 12th and 13th of July, 2016. Based on this review, suggestion for modifications of these proposals has been made.

    4. Preliminary cost has been estimated by an ADA internal cost committee and a preliminary draft CCS proposal report is prepared based on this cost estimates for possible submission later.
    5. Work on latest GHATAK configuration 2.3

    12.2 Status of Power plant & “In-principle” of GHATAK Project: GTRE had submitted a draft CCS proposal for a Dry engine for the GHATAK along with “In-principle” approval of GHATAK Program to ADA.
    After clearance from MoD and MoF, draft was submitted by GTRE to the PMO. A High Level Committee was set u p u n d e r t h e C h a i r m a n s h i p o f Dr. R Chidambaram (PSA to GoI), with Dr. V K Saraswat (Member, Niti Aayog) and Dr. K Radhakrishnan (Former Chairman ISRO) as members. The committee has submitted its report to the PMO.

    12.3 C o n f i d e n c e i n d e v e l o p m e n t o f GHATAK aircraft by ADA The committee endorsed the confidence in the GHATAK aircraft development by ADA based on the design capability assimilated in ADA in developing the Light Combat Aircraft (LCA) being utilized for configuration finalization
    for “GHATAK” aircraft.

    12.4 Recommendations of the committee T h e U C A V a i r c r a f t a n d e n g i n e technology is highly classified and is unlikely that any country would share this technology with India. Hence it is inescapable requirement to develop an Indian UCAV and its engine considering the future combat warfare scenario. The
    development of an unmanned combat aircraft is a “national imperative” toward self reliance in aerospace technologies. The committee strongly recommended the sanction of the project at the earliest to be at par with other developed countries.

    12.5 Work share allocations for the program:
    The committee also submitted the work thare allocation of for executing the GHATAK aircraft program with program office and prime responsibility with ADA, and indicated responsibility to DRDO, HAL & other labs.

    12.6 Way Forward: At the moment no GHATAK aircraft program has been sanctioned to ADA and only funds for developing advanced Technologies have been sanctioned. Using these funds some of the critical
    technologies will be developed within the country through sponsored projects.

    Under PAK FA's Auspices: Russia Develops 'Flying-Wing' Strike Drone
    A photo of an advanced Russian strike drone, which will be equipped with stealth technologies of Russia's fifth-generation T-50 PAK FA fighter, has emerged on the internet.

    The Russian website paralay.iboards.ru published a photo of a heavy Russian unmanned aerial vehicle (UAV), which is being developed by the country's Sukhoi company in accordance with the Okhotnik-B project. Sukhoi is a major Russian aircraft manufacturer, headquartered in Moscow.

    With characteristics of the new strike drone yet to be disclosed, it was reported that the 20-ton UAV will be equipped with stealth technologies of the new Russian fifth-generation T-50 PAK FA fighter jet and will be capable of flying as a sixth-generation fighter.

    Flight tests of the Okhotnik-B are due to begin already in 2018, and in 2020 it is expected to enter service with the Russian Armed Forces.

    Hunter-B drone project
    Judging by the Okhotnik-B photo, the drone is being developed in line with the "flying wing" scheme stipulating a three-column chassis. In the same way, the Skat drone was created by the Russian aircraft corporation MiG in the 1990s, something that prompted experts to suggest that some Skat technologies may be used in the Okhotnik-B.

    According to unconfirmed reports, the range of the Russian heavy drone will stand at about 6,000 kilometers. It means that the UAV may be equipped with the turbojet two-circuit engine AL-31F, which is used in the Russian fighters of the Su-27 family.

    In an interview with Sputnik, Russian military expert Denis Fedutinov, for his part, suggested that the Okhotnik-B's silhouette may look like that of reconnaissance and strike drones developed by European and US companies.

    "Judging by data on the Okhotnik-B's takeoff weight, it is safe to assume that its characteristics will be similar to those of the US drone X-47B developed by Northrop Grumman. It can fly at high subsonic speeds, operating within a radius of up to 4,000 kilometers and carrying a diverse target load, including the strike one which weighs up to 2 tons," Fedutinov said.

    Earlier, Russian Deputy Prime Minister Dmitry Rogozin told Sputnik that Russia had swiftly reduced, and is expected to completely eliminate, its lag behind the United States and Israel in the creation of UAVs.

    "Concerning the UAVs I should only say that there is no point of speaking about some lagging behind. It has been rapidly reduced and will be completely eliminated soon," Rogozin said in an interview.

    He specified that he was speaking about both combat and reconnaissance drones.

    For India Ghatak UAV project - slow movement of collaboration with Dassault nEUROn could result in Russia gain.... (all 3 same design, same role)

    Another Dassult advantage which it could lose out due to apathy to these matters - Reminds me of an old saying likely to be said for Dassult in a few years if Russia collaborate, which it be more than willing with India "Ab pachatae hoot kya, jab chidiya chug gayi khet" English : "Why repent now, when the bird has already eaten the crop"
