Investigation of a highly loaded two-stage fan-drive turbine. Volume V. Phase III. Boundary layer control optimization and off-design evaluation. Technical report 1 Jan-30 Jun 70
A comprehensive, four-phase, three-year program is in progress to investigate methods of improving the performance of fan-drive turbines. The goals of this program are to develop turbine design procedures and aerodynamic techniques for efficient, high work, low pressure turbines. The first phase effort of defining the preliminary turbine design has been completed and the results were reported . The second phase consisted of an experimental evaluation which included establishment of both two-dimensional loss levels and three-dimensional flow behavior for the baseline airfoils, and for airfoils utilizing various boundary layer control methods. The design of the baseline cascade packs and the annular cascade performance of the baseline airfoils has been reported. The annular cascade results of the baseline airfoil boundary layer control methods are reported . The results of the plano-cascade, two-dimensional, baseline investigation the decreased solidity annular-cascade airfoil test results, and the Phase III boundary layer control optimization and off-design evaluation are presented .
