Investigation of a Highly Loaded Two-Stage Fan-Drive Turbine. Volume I. Phase I. Preliminary Design Evaluation.
Abstract
A three-year program was initiated to provide a direct attack on the problem of attaining high efficiency in highly loaded turbine stages. The goals of this program are to develop turbine aerodynamic techniques and design procedures for efficient, high work, low pressure turbines by means of analytical studies and cascade testing, and to demonstrate the effectiveness of the techniques and procedures by designing and testing a two stage turbine that meets or exceeds the contract stage work and efficiency goals. The first phase effort described in this report was directed toward defining a turbine design with the highest inherent resistance to boundary layer separation and to select boundary layer control techniques that are best suited for extending the loading limits of the basic turbine design.
