    Knowingly or Unknowingly we have allowed foreign agencies play havoc with our defense R&D in past.
    From poaching, to framing to killing our talent. A batchmate of my brother from IIT-R who joined DRDO was murdered long back.... Hope this has changed and we are able to retain & protect our talent.

    Yes !! worst part is there is no significant compensation, my brother's batch mates collected some significant money to insure that his kids study is taken care of.
    Biggest fear of defense scientists is being blamed for spying.... and it is used in internal politics too, that fear is so big that they are OK with delays.

    Without airframe changes,
    update cockpit - panoramic cockpit display, bubble canopy, wires replaced by optical fibres, conformal fuel tanks, better access panels

    With airframe changes, in addition to the above-
    DSI Intakes, stealthier nosecone, twin tail, frontal stealth, conformal weapon pods, lerx or levcons, retractable fuel intake

    I guess the fear of spying exists everywhere, in relation to defence affairs, but we need to take better care of our scientists and soldiers -
    143 scientists quit DRDO since 2014, says Arun Jaitley

    Sahayak system is still not completely removed, OROP not completely implemented

    My take:

    1) Multi ejector racks (This should be the top priority)
    2) Supersonic drop tanks (This research is already done by ADA)
    3) fuselage hugging centerline drop tank which increases the fuel capacity and improves aerodynamics unlike current drop tank.
    4) LEVECONs just like Naval LCA (This research is already done by ADA)
    5) Raised Canopy (like in Naval LCA).

    Weight can always be reduced with improved technologies gradually with time.

    Why Levecon's ? Air force doesn't have landing speed issue... and levecon's will add weight to already heavy LCA.

    You mentioned Rafale and foreign suppliers. I would use the carrot and stick policy and tell the French that they might get more Rafale orders if SNECMA can help Kaveri meet the requirements.

    We already got General Electric to supply us with turbines for the LCA. Even after this, I would expect a more favourable attitude towards the LCA. It is a light fighter, so it cannot be expected to perform a large numbers of tasks. It was meant to be a high-altitude interceptor, and it should do that job well. That is good enough for me.

    A lot of the research is done by university students. Many universities contributed towards the Mars Orbiter Mission. I hope the same is being done with other projects, especially the LCA. Not all the scientists contributing to the project have to be full time employees of DRDO.

    P.S.: Batman/OROP are better discussed in their dedicated threads.

    Wrong. Certainly we need some AESA and EW at this stage but we are very much capable of improving platform itself.

    LEVECON's act like canards in some regard, they improve lift making LCA a more potent interceptor.

    Better aesa radar, avionics, and uprated kaveri engines will be great addition to tejas.

    Thrust vectoring nozzles, distributed aperture system, active cancellation system.....

    Now I get it....why RFP writing is fun :biggrin2:

    If LCA MK2 is going to have a redesigned structure with increasing dimensions why not use the designs of stealth aircraft for MK2 and make it near 5th gen with all the goodies mentioned above.. All I wish is increased range, more sorties and more payload to bomb the hell out of the porkies and chinks...

    It will become single engine AMCA won't it..... and to do that best way will be to get AMCA flying and then convert it to single engine version.
    My above comment was in lighter note as to how RPF's are written :bounce:

    A strike aircraft must have two engines. It is better to have two engines with x kN thrust than to have one engine with 2x kN thrust. The idea is that since it is a strike aircraft, if for any reason one engine is disabled, the aircraft can limp back to its base.

    Majority of the strike aircraft have two engines. In the list below, 7 out of 10 aircraft have two engines.

    Here is a list: Top 10 Attack Aircraft

    I think AMCA must have two engines. LCA can be improved to carry more fuel and if that happens, it can do a decent job in the strike role. However, one must keep in mind it was meant to be a replacement for the MiG-21 and it must do that job well. Everything else is secondary.

    I think we should try a hand ar swept wing too. Maybe asking for too much. But just a prototype to learn.

    What do you mean by "we should try our hand at swept wing" aircraft?

    We've already done that, albeit with some foreign help.

    HF-24

    Did you mean variable-geometry aircraft aka swing-wing aircraft?
