Design for High AN² (Disk and Blade attached)



The objective of this topic is to develop ad-hoc and innovative methods and criteria in order to face the challenge to correctly design and predict stress level in innovative High Speed Power Turbine for next generation geared engine application. Those methods will be then validated through an extensive test campaign (both component test & spin rig test).
AN2: turbine blade stress is proportional to AN2. AN2 is the product of the annulus mid-area along the rotor blade A and the blade rotational speed squared N2
