AXIAL FLOW REVERSING TURBINE STUDY. SUPPLEMENT TO INTEGRATED GAS TURBINE POWER PLANT DESIGN STUDY

The main purpose of the study is to establish the feasibility of an axial flow reversing turbine. The effort was divided into two primary areas: determining the rotation losses of the idle astern buckets when operating ahead, and developing an acceptable aerodynamic design which conforms to current mechanical and metallurgical criteria. The total losses of the astern section when operating at rated ahead conditions amount to 2.7 percent of the ahead power, with a 2 percent reduction in overall thermal efficiency of the power plant. This compares very favorably with conventional reversing means, particularly the controllable and reversible pitch propeller. The aerodynamic and mechanical design efforts resulted in a compatible stage design which should have a minimum of manufacturing, assembly, operating and maintenance problems.
