Magnetic Bearings and Levitation Dynamics

Failure of second-stage mechanical device control surface of a typical Russian fighter-class aero-engine has resulted in few accidents and lots of incidents. With the exception of this, throughout producing stage there was high rejection rate. of this control surface in wave fatigue tests. Metallurgic investigations of the unsuccessful control surface reveals that the mode of fai1ure. the assorted reasons of this cleft square measure micro-inclusion, oxide embedment and chemical element attack. This was analyzed from the 3 completely different approaches, namely, theoretical stress analysis, basic style and internal control. To contain the chance of oxide embedment and element attack, sand electro-comdum blasting and measure-replaced blasting are taken to manage element embedment.
