Aerothermal Technologies and Design Tools for Advanced HP Turbines
Abstract
The design of advanced turbines has to meet ever more ambitious requirements. Higher performances and component life must be reached within shorter design cycles at lower cost. Snecma Moteurs is building up an extensive experience in the design and manufacturing of the next generation of high-pressure turbines for military and commercial aircraft engines. The purpose of the present contribution is to report on the recent advances in the design of cooling technologies for High Pressure (HP) turbine blades. First of all, the new concepts of advanced cooling circuits are described and their interests in terms of life duration put into relief. Several examples demonstrate the way these new advanced cooling technologies can be optimized by carrying out high-tech Computational Fluid Dynamics (CFD) methods. Finally, validation cases of the aerothermal methodology analysis built up at Snecma Moteurs are detailed. They present the interest of being focused on engine tests results and show the degree of performance and quality that Snecma Moteurs HP turbines aerothermal technology and design tools have now reached.
