After 6 test run fore a total of app 8-10 minutes running it was time to try the turbin in my Rafale. Fuel system had bean flushed several time and everything was ready for the big day. Turbine spool up fine to idle but seams to hesitate fore a half second on its way to full throttle. Back to idle after about 10secund at 145000 rpm. Next I gave full throttle but at 70-80000rpm it was over. Suddenly stop and a terrible sound. I use pressurised air to cool down turbine. Front compressor damage and everything is total stuck. Can&rsquo;t turn anything. During 3 test run in test jig I notice high speed vibration at app 70-80000rpm so this turbine has to be out of balance from factory. I haven&rsquo;t done any modification or loosen any bolts other than turn outlet cone so temp sensor fit my mounting. What now? Return turbine to factory?</span>
