    If it is for Tejas Mk1 your information of the intake optimised for 77 kg/s is contracditory with "longstanding design flaw in the Tejas air intake".

    PESHAWAR: A Pakistan Air Force (PAF)Mirage aircraft crashed Wednesday afternoon in Miran area of D I Khan district.

    District police (DP) has so far confirmed deaths of both the pilot and the co-pilot. The bodies have been mutilated beyond recognition.

    Officials said the plane was on a training flight when it crashed. They added that during the flight, there was torrential rain and lightening which may have caused the crash. The DP office added that rescue teams have been dispatched to the area.

    The PAF spokesperson has ordered an inquiry into the crash.

    The plane crashed in Chirra, Miran situated around 80 kilometers away from D I Khan. Eyewitnesses said the plane caught fire during the crash.

    There are conflicting reports on the intake design of the Tejas.

    Ajay Sukla, in the article you've posted, has written that the intakes are barely large enough for the F404. But Saurav Jha writes:

    To clarify, Tejas was designed for the Kaveri Engine. The GTRE designed Kaveri engine has an airflow intake of 172 lb/s (78.0 kg/s), while the GE F404 IN20 has an airflow of 153 lb/s (70 kg/s).

    Next, Prasun Sengupta reported the following in 2011:

    This conflicts with the earlier suggestion that the current intakes on Tejas will permit enough air for even F414. According to General Electric's own documentation, the F414 engine takes in 170 lb/s (77.1 kg/s). However, people (including vstol jockey) have stated that the GE F414 INS6 variant will generate more thrust than previous F414 variants: they have also suggested that INS6 will be based on the GE F414 EPE project, which is stated to generate maximum thrust of 115-120kN, so the airflow of the engine will be higher than currently stated. Perhaps the intake will be redesigned to permit this higher airflow requirement.

    what is the air flow required for generating maximum thrust of 115-120kN ?

    Yes M88 has much better fuel consumption(lower) than F414.

    Original Tejas did not have auxiliary intakes. The LSP series had them just to make up for any shortcoming in intake air flow.

    Strange that even on JF-17 thread you folks are talking about LCA and the french members as usual are peddling their wares in most threads
    If you want to discuss LCA, there is LCA thread. BTW HAL has selected F-414 Engine guess that closes the matter.

    Increase the thrust is a solution "in force" the US method, we prefer methods "with finesse" : The Tejas is a light aircraft, it must be able to increase its performance without increasing the thrust.
