The purpose is to acquire knowledge about rotating machines design. Application domains are turbojet engine dynamics, shaft dynamics, micropumps, electrical turbines... Notions seen in UE MSS and GM are extended: technological, modelling and experimental knowledge are given to nderstand dynamic aspects of products by Safran - Snecma, Safran - Turbomeca, GE, Siemens, Alstom Power, Rolls-Royce, EDF, Pratt&Whitney...
