概要

論文の詳細を見る
Recently, the demand of making a higher load and more efficient jet engine has strengthened further. In the design of fan and compressor blades, flutter prediction is a critical factor. Numerical simulation is performed for transonic stall flutter of a research model fan with 3D unsteady NS code. It is shown that the imaginary part of unsteady pressure at the shock impingement point causes the blade instability.
