A possible shaft failure event can trigger a number of mechanisms affecting the mechanical integrity particular of turbine discs and blades. A predominant aim in engine design and development is to satisfy that passenger lives are not to be endangered by the release of high energy debris. In a typical Intermediate Pressure shaft failure scenario of a 3-spool high bypass ratio turbofan engine, a potential mechanism to limit the terminal speed of the free running turbine, within acceptable values, is proven to be the impact of the free running turbine with the following stationary arrangement.
