    Nice pics, yeah the difference is huge in terms of cockpit hump and ugly fairings.

    I wonder how large the cockpit transparency is going to end up being on the final product, seems to be a bit of difference in the photos where the avionics start @ the rear.

    Yup, the canopy transparency may end a little earlier, as seen on the model that was displayed at Aero India 2017, for manufacturing reasons. But the overall refinement and improvement in the design is apparent, with the 1m fuselage extension, the 700mm width increase and the change in the fuselage where its cheeks seem to be squeezed a bit (like on the Rafale).

    There has been a lot of work done on refining the aerodynamics. Such as how to improve drag on the aft portion of the fuselage, studies to add strakes to improve the high AoA CnBeta controllability, change the canopy geometry, etc.

    Do you happen to know where the 1meter fuselage "plug" will be, or is it spread throughout the frame? Will the wings be modified accordingly? This sounds like some serious work, but along with canopy profile will lead to a really smooth looking jet. Always though the cockpit hump made the Tejas look really stumpy.

    A lot more interesting than the AF variants, makes the long time we have all been waiting more tolerable.

    Yes, the 1m plug was supposed to fit in right aft of the cockpit, where area ruling studies showed there was a drag increase due to the shape of the canopy.

    There's a 1m extension on the LCA Navy Mk2 and 0.5m on the LCA AF Mk2. Due to the fact that the LCA AF Mk2 has been in work for longer than the LCA Navy Mk2 and had its SOP frozen by 2013-2014 itself.

    From ADA

    The main contributors to improvement in LCA(Navy) Mk2 have been identified as higher thrust engine, an increased wing area, an area ruled and
    streamlined configuration, lighter landing gear and structure, and improved systems layout towards better safety and maintainability.
    LEVCONs may be converted to active surfaces.

    Proposal to convert LEVCON into an active surface permitting operations with higher instability to achieve improved agility and performance
    Change in airbrake location from dorsal to ventral
    Alternate ventral airbrakes performance with low interference.
    Changes in the air intakes based on CFD analysis that has been done

    Redesign of air intake for bigger GE- F414-INS6 engine, with lip and cowl profiles and auxiliary doors optimized for superior performance at low speeds for
    improved carrier launch capability
    And here is why ADA believes the LCA Navy Mk2 will be able to meet the IN's requirements

    Mission performance analysis for three IN profiles viz., Air Defence, Anti ship and Ground strike were carried out. Point performance compliance status with
    respect to ASR was also evaluated.
    The structural mods

    Preliminary Structure Layout with zero thickness model for NMG Version V0.06C for Front, Centre & Rear Fuselage incorporating 1020 mm longitudinal plug, 700 mm lateral plug. Concept studies of alternate Structural Layout for iterations on Inboards layout based on System requirement were undertaken.
    No ballast
    Improving performance in terms of low supersonic wave drag, acceptable cg limits for stability and control criteria for zero ballast design.

    In this angle the CG looks beautiful also due to the lack of those APU intake.

    But regardless of these beautiful stuffs I'm not very optimistic nor enthusiastic about a naval Tejas, whatever version it may come in. A single engined fighter is not the best of the platform for the decks no matter how much fanboys want to sing about engine reliability. So Tejas or the Naval Gripen which the Swedes are trying to push in will only become more of a liability due to them being single engined and smaller aircraft. The base capability on the deck should be a medium sized aircraft like MiG-29K and any capability addition should be on top of it, not below it.

    In addition, last year and during past months we saw a lot of moaning from the paid plants and idiotic fanboys on MiG-29K and its single-engine "certification" for carrier deck operation. If we are to take the same "certification" criteria of safe landing/operation for Naval Tejas/Gripen.....with its only engine out of operation, what is it going to be?
    Glide Ratio of the airframe I suppose?!

    LCA Navy Mk2 program details from ADA. Just about as detailed as one can get. Clearly, the program is in advanced stages of design and prototypes of the LCA Navy Mk2 will be built.

    LCA Navy Mk2
    9.2.1 Programme

    Govt. of India sanctioned development of two LCA(Navy) Mk2 single seat Fighter prototypes (NP3 & NP4) under FSED Navy Ph-2. The LCA(Navy) Mk2 is being designed primarily to provide air defence to the fleet onboard Carrier and meeting all the mission objectives set out by the Indian Navy. Significantly
    improved aircraft performance largely better than AF-Mk1 and integration of full suite of weapons are capabilities inherent in the design.

    The main contributors to improvement in LCA(Navy) Mk2 have been identified as higher thrust engine, an increased wing area, an area ruled and streamlined configuration, lighter landing gear and structure, and improved systems layout towards better safety and maintainability. Flight control features to reduce approach speed even with an increase of around 2.5 tons of Carrier landing mass is a critical capability over LCA(Navy) Mk1. System Requirements Review (SRR) with participation of Indian Navy (IN) was carried out in detail with requirements capture and document prepared.

    Concept design of LCA(Navy) Mk2 has been completed and detail design phase initiated. A detailed Preliminary Design Document for LCA(Navy) Mk2 has been prepared and provided to IN. Carrier compatibility requirements of INS Vikramaditya and INS Vikrant have been captured and necessary features incorporated in design. Based on requirement to consider wing folding to overcome the aft lift interference on INS Vikramaditya, a Technical Note was
    prepared and submitted to IN. The note details rationale behind Wing outboard shift for LCA(Navy) Mk2. Issues in not opting for a wing fold and also restrictions in carrier take of mass if the wing is retained as in Navy Mk1 was brought out.

    A meeting chaired by RM on 27 April 2016 was conducted at MoD, Delhi with participation of IN to review LCA(Navy) Mk2 Programme. IN had brought out
    performance comparison of LCA(Navy) Mk2 with MiG-29K with respect to ASR/85. In order to improve aircraft performance dedicated task teams have been constituted working towards mass and drag reduction.

    A comparative performance study of various naval combat aircraft was carried out with Airbus DS consultants and presented to stakeholders.

    9.2.2 Design & Development Activities
    (a) Aerodynamics & Configuration:

    Air Vehicle Configuration of LCA (Navy) Mk2 is a critical activity during the concept design phase. The major activities carried out are:
    NMG V0.6L has been base lined for detail design
    Improving performance in terms of low supersonic wave drag, acceptable CG limits for stability and control criteria for zero ballast design.
    Optimized LEVCON & Shelf Flaps to achieve approach speed reduction for carrier landing.
    LEVCON converted into an active surface permitting operations with higher instability to achieve improved agility and performance.
    Ventral Airbrakes for performance with low interference
    Air intake redesigned for bigger GEF414-INS6 engine, with lip and cowl profiles and auxiliary doors optimized for superior performance at low speeds for
    improved carrier launch capability.
    1:10 scale low speed wind tunnel model fabricated at NAL and was tested in the HAL wind tunnel.
    Wind tunnel data correlation study with CFD simulation carried out and found to match very well.

    Based on the iterations carried out in configuration performance evaluation was also computed to arrive at optimum solution. The major activities undertaken are:
    Installed performance estimation of new GE-F414-INS6 engine in LCA (Navy) Mk2 was carried out
    A comparative study on performance with contemporary Naval aircraft was carried out and shared with IN.
    Mission performance analysis for three IN profiles viz., Air Defence, Anti ship and Ground strike were carried out and has been established to meet the IN
    requirements. Maximum capabilities in various IN defined missions to bring out margins available has also been evaluated.

    (b) Airframe and Mechanical systems:
    Airframe:
    Preliminary Structure Layout with zero thickness model for NMG Version V0.06L for Front, Centre and Rear Fuselage incorporating 1020 mm longitudinal plug, 700 mm lateral plug. Concept studies of alternate Structural Layout for iterations on Inboards layout based on System requirement were undertaken.

    Main Landing Gear (MLG) interface with Airframe has been defined. This involved studies for MLG load path and definition of structural attachment to fuselage. Structure layout for Nose Landing Gear (NLG) to suit the modified aircraft geometry is in progress. Arrestor hook structural integration concepts for different schemes were carried out. Finite Element Model (FEM) of Airframe was prepared and detailed stress analysis for critical carrier landing load conditions evaluated. As a result of this analysis it is found that the bending moment loads for most critical 2 point landing case on the fuselage is around 30% lesser than in Navy Mk1. This was identified as a potential weight reduction opportunity and a detailed study undertaken.

    Fuel tank layout to meet increased internal capacity and c.g management has been defined to carryout detail design. The Airframe team took active participation in workshops and webex discussions with Airbus DS team at ADA to converge on a feasible structural design solution. Detail design of Airframe is in progress and CAD models/drawings are being created in concurrent design environment.

    Landing gear & Arrestor Hook:
    The MLG configuration of LCA (Navy) Mk2 with optimized structural interface made feasible by means of 350 mm additional space in the Y-direction of the aircraft has been finalized.

    Following actions have been carried out:
    General Arrangement of Landing Gear System.
    Estimation of Landing Impact & Ground Manoeuvring Loads.
    Kinematics of Main Landing Gear & LG Doors
    Sizing of tyre and wheel size
    Kinematics of Nose Landing Gear & Doors has been updated to suit the new geometry V0.06L
    Arrestor Hook design as a conformal concept with Y-hook arrangement is being progressed by ARDC.
    Forcing function loads & Estimation of AHS Jack Loads has been carried out.

    Engine:
    Higher thrust Engine GE-F414-INS6 is to be installed in LCA(Navy) Mk2. Updated Performance Cycle Deck(PCD) and CAD model of the Engine made available for design studies. ASMET and other qualification tests have been successfully completed by GE, USA and delivery of engines scheduled.

    Fuel Systems:
    Top level requirements of fuel system was finalized with the involvement of Indian Navy. LCA(Navy) Mk2 is conceptualised with active fuel flow proportioner transfer system. The concept was finalized based on interface definition with interdisciplinary design teams. Fuel system design of LCA(Navy) Mk2 is supported by Airbus DS as part of engineering support in the Design Consultancy. Based on the above, Interface control documents for Fuel system with other systems that include Propulsion system, Avionics, Secondary Power System, Hydraulic system, structures, Environment Control System and Control law were prepared and provided to Airbus DS team for their comments and feedback. As an inherent feature of active fuel transfer system, pumps are installed in all fuel tanks. Electrical Power requirements in normal and emergency modes for this system was estimated.

    Development activities initiated for procurement of smart fuel system components such as digital fuel gauging probe, optical level sensor, transfer pumps
    with inbuilt pressure transducer and Nonreturn valves, intelligent line replaceable units(LRUs) for pressurization and venting system, etc., with original equipment manufacturer (OEM).

    (c) Flight Control System and Control Law:
    Preliminary Design Document for IFCS including IFCS Architecture released. Study of alternate configurations for Active LEVCON including Single / Multiple
    Linear Actuators was carried out. TEX flap introduced for reducing approach speed which would provide ~5 knots speed reduction. Usage of available Electromechanical / Electro hydraulic actuators for Shelf flap is under finalization.

    Control Law (CLAW):
    Based on the configuration changes carried out in LCA(Navy) Mk2 and the Aero data provided by Aerodynamics group, simulations were carried out and based on results obtained, detailed interactions with Airbus DS consultants have been effective towards finalizing LCA(Navy) Mk2 configuration.

    (d) Avionics & Weapon systems:
    The Avionics architecture of LCA(Navy) Mk2 is to be adapted from the LCA-AF Mk2. Navy specific features are to be implemented based on interactions
    currently in progress with Indian Navy. Feedback on AESA Radar and Communication interface has been received from IN. Network communications requirements has been sought from IN. Preliminary cockpit layout study for 19.8 Degree HUD has been carried out and feedback provided to CSIO, Chandigarh who are developing this LRU. Studies for integrating Automatic Carrier Landing System (ACLS) have been initiated with participation of IN.
    Interaction with NEC, Mumbai, to capture EMI/EMC interface requirements on Carrier carried out.

    (e) Test Facilities / Rigs:
    Shore Based Test Facility (SBTF): The existing SBTF at Goa would be utilised for shore based testing of LCA(Navy) Mk2. Landing gear test rig: Development of test rigs to undertake full qualification of MLG & NLG and Nose wheel steering is planned.
    Fuel System Rig: A fuel system test rig to evaluate the fuel system performance with emphasis on transfer sequence and its reliability is planned.
    Iron Bird: Iron Bird-3 is planned to be set up at ARDC for qualification of FCS.

    9.2.3 Airbus DS Design Consultancy
    Quarterly workshops involving Aircraft design experts in major disciplines is in effect as part of Design Consultancy with M/s Airbus DS, Germany. The experts visit ADA for interactions with respective design teams. Based on the Design suggestions, design teams involving Aerodynamics, Structures and various groups have evolved Concept design of LCA (Navy) Mk2. ARDC, HAL as principal partner is involved in these design activities. The last 3 quarterly workshops (Total 11) planned as part of detail design phase has to be rescheduled and hence a requirement for PDC extension of this design consultancy
    up to Dec 2017 is needed.

    9.2.4 Follow Up Activities planned
    a) Detail design of LCA(Navy) Mk2
    b) High speed wind tunnel model fabrication and tests for force & moment and air intake
    c) Development of Assembly Jigs
    d) Raw material procurement
    e) Fuel test rig

    From AW&ST


    India Ponders Exporting Tejas Fighter


    India is looking to aggressively market its homemade Tejas light combat aircraft (LCA) and the upgraded Advanced Hawk trainers it builds with BAE Systems to international buyers.

    “Apart from the Indian Air Force (IAF), we are looking at several Asian and Middle Eastern countries for the export of the LCA,” a Hindustan Aeronautics Ltd. (HAL) official says.

    The Indian military has approved the purchase of 83 LCA Tejas Mk. 1As for the Air Force at a cost of 500.25 billion rupees ($7.5 billion) to replace aging MiG fighters. This is in addition to the 40 Tejas fighters previously ordered.

    In 2016, Sri Lanka and Egypt expressed interest in the LCA. Last year, the Sri Lankan government discussed its intent to buy 8-12 new multirole combat aircraft for the Sri Lanka Air Force (SLAF). Both the Tejas and Advanced Hawk are possible contenders to meet the requirement, as Sri Lanka reportedly rejected Pakistan’s offer of its JF-17 aircraft jointly developed with China.

    HAL says a number of countries in Asia and the Middle East have expressed an interest in its Tejas light combat aircraft.


    “Should the SLAF desire a supersonic multirole aircraft, India’s Tejas Mk. 1, despite its still being in the developmental phase, could be a viable option,” an Indian defense ministry official says.

    HAL currently can build eight LCAs per year. There is a plan to ramp up the production rate from eight to 16 aircraft annually by 2019-20.

    The Advanced Hawk could fit the bill as a subsonic light combat aircraft or trainer. “The large fleet of BAE Hawks operated by the IAF and the strong overhaul and maintenance facilities available in India could make the Advanced Hawk attractive to the SLAF and several other air forces,” the ministry official says.

    The UK government agrees on the Advanced Hawk’s export potential. “I am here not just to see what more we can ‘Make In India’ or make with India, but to see what more we can design, develop, add value with India and export together to third countries and to new markets,” says Michael Fallon, UK secretary of state for defense, who is currently visiting India.

    Looks like the Mk2 AF will get the 0.5m plug and the Mk2 Navy will get the 1.02m plug.

    I also found this detail to be interesting:
    - HMDS based on optical sensor
    Possible IRST?

    Tejas test fires guided Derby BVRAAM and successfully hits target

    Continuing with its successful stride of flight trails with missile tests, ADA's Light Combat Aircraft (LCA) TEJAS achieved a major milestone on Thursday. One of the limited series production (LSP) platforms fired a Beyond Visual Range Air-to-Air Missile (BVRAAM) missile Derby and scored a direct hit, the test was conducted at the Interim Test Range, Balasore.

    According to sources associated with the project, these weapon trials are part of the Final Operational Clearance (FOC) mandate.

    Sources confirmed to IDN that the TEJAS fired the BVRAAM Derby missile on a Ballistic Guided mode.

    Tejas, the Light Combat Aircraft, today successfully demonstrated an Air-to-Air Beyond Visual Range missile firing capability by releasing Derby Air-to-Air BVR missile in RADAR guided mode.

    The missile launch was performed in Lock ON after Launch mode for a BVR target in the look down mode and the target was destroyed.

    The objective of the test was to assess the Derby integration with aircraft systems on-board Tejas including the aircraft avionics, fire-control radar, launchers and Missile Weapon Delivery System and to verify its performance.

    The test was conducted on a Manoeuvrable Aerial Target at the Interim Test Range (ITR), Chandipur. The sensors at ITR also tracked the target and missile.

    A safe separation was followed by missile guidance towards RADAR acquired target.The flawless launch was demonstrated with all on-board systems performing satisfactorily and the missile scored a direct hit on the target with complete destruction of it.

    The test firing achieved all its planned objectives.

    The Derby firing is a major step towards clearing BVR capabilities on LCA aircraft for FOC.

    Given the latest single-engine fighter request from IAF, will MK2 be only for Navy now?

    No, in fact it is the IAF which is the most interested in the IAF Tejas Mk2 variant now. the LCA Navy Mk2 development will continue with the Govt. providing funding, but it will have to prove itself for the Navy to accept it.
