    Miniaturizing a turbofan is an equally tough task...... Yeah metallurgy of today is better, but still it's not a cup cake baking.

    Tw of Tomahawk engine is better than the Manik..... That's why we need to reduce weight and increase thrust.

    I was referring to standoff missiles like JASSM. But turbofans are more fuel efficient and better suited for loitering.

    Yeah cruise missile turbofan is so difficult that USA just gave away the technology to Japan, Korea, Turkey. Even Pakistan could make BABUR missile.

    Turbo jet also uses kerosene or Jp4 or similar.. Solid fuel is used only for Rocket engines and used for certain types of missiles.

    Concorde used Turbo jet engines and Russian Tupolov TU -40 used turbo fan engines Other than that the post is engine spec

    Yeah and Babur missile uses Chinese turbofan, Japan has its own RnD and Koreans and turkeys using American engine in their labeling.

    Do you know that the core section of a turbofan is also known as turbojet. And since when Mig21 started using solid fuel... When did Exocet missile (being subsonic) started using turbofan....

    In second test, it had done 1000+. Every test need not be full range test.

    Hi guys. Mach is referred in two way. One is 1200 KM/Hr and another is some 1030 KM./Hr.

    Every AAA & SAM is design to intercept low flying targets ..

    SA-6, SA-8, Akash and other AAA practice such on routinely basis ..

    Mach is speed of sound. It is the same definition everywhere. It can change its value at different temperatures and altitude. Mach at sea level at 25 degree celsius in 1224kmph. At 30000-35000 feet altitude it is 1030kmph. Speed of sound is not constant

    True. That is what I say. Mach no is a ration of speed of object in particular medium to speed of sound in same medium (i.e at particular temperature and pressure). It is that is why very confusing. Better speed be mentioned in KM/hr.

    Be clear that the air viscosity depends on Mach number. Mach is a natural phenomenon and hence is prioritised.

    Planes also have varying maximum speed at different altitude. Plane speed is also not fixed. They are just approximate speeds stated. It is indeed convenient to use kmph but that too has its flaws

    You are quoting anti ship missiles that have range of 1km for every 4-5 kg of missile weight. I was speaking of long range subsonic missile. All your missiles has 700kg weight and 150km range!

    I made an obvious mistake - i said that turbojet is impossible for subsonic missile. Reality is that it is false as turbojet is capable of subsonic and turbofan capable of supersonic. However, the purpose of turbojet is defeated if it is used in subsonic ones due to its high fuel inefficiency. Its range will be pathetic for its weight. It is possible to use turbojet for subsonic but is FOOLISH and not feasible for long range missile.

    Please stop nitpicking on minor details. I am not perfect, nor do I claim to be a vocabulary expert. I can make mistakes while conveying my ideas but if it is a minor vocabulary error or minor exaggeration, it is necessary to swallow it and take the spirit of the words.
