Objectives

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...
