A comprehensive three-year program is in progreL,J to investigate methods of improving the performance of fan-drive turbines. The goals of the 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 by designing and testing a two stage turbine that meets or exceeds the contract stage work and efficiency goals. The first phase effort defining the preliminary turbine design has been completed and the results have been reported. The second phase consists of a preliminary experimental evaluation which includes establishment of two-dimensional loss levels and three-dimensional flow behavior for both the baseline airfoils and airfoils utilizing boundary layer control devices. The design of the rig hardware and the baseline airfoils which will be evaluated during this second phase are presented in this report.
