A24-042 DEVELOPMENT OF MICROMACHINE GAS TURBINE FOR PORTABLE POWER GENERATION

概要

論文の詳細を見る
Micromachine gas turbine with centrifugal impeller of diameter 10mm fabricated by 5-axis micro-milling is under development at Tohoku University, in conjunction with Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI), Tohoku-Gakuin University, and Sankyo Seiki Mfg. Co., Ltd. The development is currently at the stage of proving the feasibility of the gas turbine cycle by component tests. Micro-combustors have been developed for both hydrogen and methane fuel. Over 99.9 percent of the combustion efficiency has been realized in both combustors and the baseline configuration of the combustor for the gas turbine is set. A compressor of diameter 10mm has been developed as a micromachine turbocharger. The performance test of micromachine turbocharger has been started, and ran up to 504000rpm, which is approximately 58% of the design speed. Compressor performance has been successfully measured along constant speed line at 55% of the design speed.
