ABSTRACT
At the National Aerospace Laboratory (NAL) in Tokyo, fundamental research on turbine steady and unsteady aerodynamics has been conducted. The objectives of the research are to understand complex internal flow mechanisms in detail and find new ideas to improve turbine performance. The present paper reviews our recent work. First I will briefly review our division’s current and past projects related to aeroengine and gas turbine R&D, and then will explain the test rigs I designed, particularly for fundamental research with special features for obtaining detailed data. While explaining each test rig, I will list some of our current studies and an example result so that others can know the work roughly. Also I will review our report published in 1994 and finally summarize major work currently being done at the Turbine Laboratory of the Aeroengine Division of the NAL.
