    I think this twin engine LCA is more of a demonstrator.

    That's the problem that most people forget in this fantasy. Adding another engine to Tejas, requires a complete redesign of the center fuselage, the intake, or gearbays. You basically have a new fighter development, which is neither an easy nor a fast solution.

    No they would have taken even if France did not buy, but the French navy found that the plane was too efficient and that it threatened its boats in the Mediteranean sea.

    This is what Dassault proposed to HAL and that HAL refused.

    And as usual, bringing up Dassault in an unrelated thread. :disagree:

    You are just desperate, that's why you keep bringing up Dassault wherever you can, just as desperate F35 fan boys do it as well. When you don't have arguments and deny facts, just repeat the same falsehoods and maybe some people will believe it. What works for Trump or F35 fan boys, can't be that bad for you either right? :mrgreen:

    Did you don't know, where exactly ? OR pretending to be ignorant ?

    1. What was ADA, group of scientists and engineers from HAL 300 in numbers. And stop making funny statements making ADA and DRDO two different entity. ADA is the part of the DRDO. DRDO is the group of hundereds of labs and research centers spread around the country.

    2. For the 3rd time telling you LCA project was not the plane, rather the ability to design and build, develop the technology, fill the tecnological gap and to create the whole ecosystem of aviation in the country and in this learning process build a combat plane. If the prime target would have to get the combat plane, than HAL would simply ask the Dassault to design a single engine fighter plane just like how novi avion, IAR 95 was tried. And what properly leading and managing the LCA development -- Didn't the ADA develop the digital FBW, design the Airframe, which is flying and even participated in the first ever airshow outside India in Behrain, didn't coordinated with the 100+ labs, institution, organisations to build this combat plane. Didn't this project help India in now actaully Mig 27UPG, Jaguars Darin 2 and 3 upgrades ourself. BTW a part of the LCA project is flying with the MKI in the form of the RWR and the Mission computers developed for this project.

    3. Designing a Fighter with Drag and Wt issue ?? LOL Again trying to be ignorant or you are ignorant ?? It was clear from the start that there was no suitable engine available which was suitable for the LCA, that's why Project Kaveri was started led by GTRE. And the GE 404 engine which was selected to power the TDs and PVs could power the LCA with relaxed ASQR period. Don't want to repeat again, the whole thing which you never read, and just cheery pick few words for the Air intake designed for the Kaveri specification, and why the auxillary air ports were added latter.

    Gaining wt. during the development that initial planned is not a unique thing, even Gripen E gained more wt. than planned.

    Designing it too Small -- This is the height of Funny Logic -- Janaab already explained you previously in an ellaborate manner, but you are short of time, and never borther to read completely So for your sake, its the IAF, which was impressed with the Folland Gnat, asked for the LWF with the wt. arround the 5000 Kg, and wanted the small size so that IAF could use the existing infrastructre, Shelters of MIG 21. This is one of the reason why ADA choose the Tailess Delta Design.

    Read this http://idrw.org/was-iafs-fixation-for-lightweight-fighter-lead-to-lca-debacle/

    Designing a Suitable Nose --- Funny statement and laughable and Childish too, since the nose cone is designed by NAL --- The Nose cone is the structure to protect the radar and other EW sensors from dust, water and is lui with the Aerodynamic design of the aircraft and since it was made from the Kevlar composite, was not allowing to utillize the full power of the EL/M 2032 MMR, that's why Quartz Radome Nose cone was procured from the Cobham, UK, and its not a unique thing again. BTW the Design which is refered to is the internal structure of the nose cone, and not the external, so that minimum attenuation happens for the electromagnetic signal from the Radar's Antenna, at particular range of frequency while transmitting and returning. And for your Knowledge When found on fixed-wing aircraft with forward-looking radar (as are commonly used for object or weather detection), the nose cones often additionally serve as RADOMES.

    Here is what Cobham says in their website --
    Cobham radomes are made from composite materials in our state-of-the-art composite facility. In this facility, we have an environmentally controlled lay-up room, paint booths, autoclaves, ovens, tooling department and a 5-axis CNC machining center. Our radomes use the most optimal materials for the given applications. Our radome designs include solid wall, A-sandwich and multi-layer construction and can be tailored to virtually all typical frequencies. The materials and construction are chosen to minimize loss at the specific frequency while optimizing strength and cost.

    As far as NAL's capability is concerned, NAL indigenously designed, developed and fabricated a composite nose radome for the Fire Control Radar of Jaguar Maritime Aircraft for HAL, Bangalore, end user being IAF. In continuation to the development of 11 no. nose radomes, a request was made by HAL – Overhaul Division for transfer of technology of the Jaguar Nose Radome fabrication. The technology was latter transfered to HAL for manufacturing.

    BTW Check this out for the EF Typhoon

    What would you say about this Mamoo.

    Completely Underestimating the NLCA Design Work --- Ellaborate it with the Facts.

    Will have to call it MCA then.

    Hellfire, this twin engine LCA is the aircraft you were talking about.

    So a MCA is being planned. This is just like what the Koreans are doing. They are designing a 4th gen twin engine fighter and then a 5th gen aircraft based on it.

    I would like to see the competition the same way it happens for the X35 project between LM and Boeing. Similarly between ADA and @vstol jockey with 1 billion each and a time frame to build a prototype.

    It is wrong to assume that no good engine was available for LCA. Kaveri failed but at the same time F414-400 and EJ-200 were available. For some unknown reason ADA decided to chose F404. The basic thumb rule to design a fighter is to have an engine which has a dry thrust of at least 10% more than the empty weight of the aircraft. The targeted weight of LCA was 5500kgs. So it needed a minimum dry thrust of 6050kgs. Instead they opted for 54Kn F404. That killed the aircraft.
