    There are many points.....
    1 your typical car engine operates at 8000 rpm jet engines make do at 190000 rpm
    2 ever tried compressing air ? Its difficult enough to do it when we are standing still ... But at mach speeds?
    3 the engine should be light but also strong enough to withstand something as strong as a truck and multiple forces at all directions... So the material needs to advanced and is consequently costly
    4 the energy required to do this is very high so lots of air needs to be scooped and hence starting a jet engine is tough job
    And then there is the designers paradox.. If you make a jet engine easy to start then your performance will be bad ... Vice versa ... That's the SR71 needed to have a teb starter ... So yes designing a jet engine is tough
    Making a jet engine is actually easy..
    Operating it is tough ....

    kaveri engine has not failed. But it is stuck for want of new and strong metals which can withstand the tempratures needed for it to achieve the reqd thrust and weight.

    Because the program was too ambitious to begin with .... Only now are nickel-rhodium alloys maturing enough to go the next step of SBC ....

    AFAIK there is no seperate engine development in progress. They divided Kaveri engine into two sections.

    1. K9 Project - The Maine engine which will be installed in Tejas and AMCA/
    2. K10 Project - This project will be for future engines, making Kaveri engine as the base.

    developing a jet engine is almost 5 times more complex and difficult than developing a fighter air craft. that is why earliar also we had developed HF-24 marut aircraft but did not have capability to develop engine. had the british agreed to supply RB 199 engine to us, in HF-24 we wd have a fighter bomber which was almost parallel to anything west had at that point of time.

    that is why u have so many aircraft manufacturing companies but very less engine manufacturing companies. there is virtually monopoly of GE/PW/Rolls royce in this field.

    i think as far as india is concerned we are yet to master the metallurgy required to develop engine. we do not also have adequate R&D base in engine technology. GTRE has actually been wasting tax payer's money for several years now and HAL engine division is happy doing licence production and repairs.

    We already have such technologies within India. But, If we don't want to make something within in-house means something else. I repeated this thousand of times, the Babus, Ministers and ther folks make money while buy from outside world. This create them extra money. That money will be deposited either in swiss bank or hongKong Bank (HSBC). Then they make the same money white through investment within India. This is how tax payer's money is utilized for these illiterate bastards. I have my own sources, this is confirmed news. But, if we will not pay tax they will sieze our property. Put us behind bars, put pressure though there official gundas.

    Yes we have , the problem always has been importing it... Because most ore is found in china they are not willing to export ...
    Superalloy - Wikipedia, the free encyclopedia
    We mainly need rhodium based superalloys... Only they can fulfill india's incredible requirements
