6. 5. Lifespan improvement of bolted connection inside the turbine

   University essay from KTH/Lättkonstruktioner

   Author : Clément Helterlin; [2019]
   Keywords : ;

   Abstract : In order to reduce fuel consumption of aircraft engines, components are constantly optimized. This improvement is pushing component’s limits to the farthest they can handle. That’s why engine manufacturers have to guarantee a minimum engine lifespan. The evaluation of these lifespans is made on each component. READ MORE
