As the most promising procedure for improvement of the gas turbine efficiency, the adoption of a high pressure ratio and a high maximum temperature should be considered in its essential sense, even though its part-load efficiency is rather poor. In such a gas turbine, however, it offers a various problem-compressor surging at starting and low load operation, a comparatively high idling relative speed, the necessity of a large starting power and so on. To avoid these difficulties and raise the limitting value of the obtainable pressure ratio with single compressor, it introduces a by-pass gas turbine scheme which inserts a by-pass duct between a intermediate compressor stage and a appropriate turbine stage. In such a scheme, by-pass air at low load operation has a equivalent effect for compressor surging to blow off and at the same time, a recovery of by-pass air energy through a turbine stage improves its starting character. In this study it is intended to make clear the part-load performance of such a by-pass gas turbine and this report is the comparison of 1/C, 1/HP, 1/LP, and 1/P schemes, at the propeller law operation.
