Re: Kaveri & Aero-Engine: News & Discussion

Whatever one may say about russki engines, one has to wonder how in hell they manage to keep those engines running without surge or stall during a brutal manoeuvre (engine wise) like the Su-27 Pugachev's cobra. I also wonder about the same. I did try to find out exact technical details about it. Bu...
