| description | The speed with which a new aircraft engine is developed prevents extensive experimental testing of key turbine components. For this reason, design engineers rely increasingly on computer simulations to develop and perfect components before committing to final designs. CFD predictions can fail to accurately predict some key features of turbomachinery flows, and design engineers often seek to calibrate their designs and CFD predictions against test data. This paper addresses the use of flow and heat transfer experiments in the context of turbine cooling system development. It reviews how experiments can be used to support both research activity and the engine development program (EDP). The paper describes the state of the art in Perspex model test technology and the introduction of rapid prototyping (RP). This paper reports applications of these models to aerothermal testing of turbine component and reviews the advantages and the shortcomings of such testing. The paper focuses on the stereo-lithography (SL) technique as this remains the most popular method for producing test models for aero-thermal tests. The paper also explains how judicious use of RP test data can be used in cooling system development to arrive at optimal systems. © 2010 Begell House, Inc. |
