Outline of Final Research Achievements

This study was conducted to show that the Fluidic Thrust Vectoring (FTV) technique is an effective approach for aircraft attitude and is more effective than the conventional attitude control method. A system that automatically flies around a predetermined course and a logging system that collects and stores various types of flight data was developed to enabling quantitative performance evaluation of FTV system through flight tests. Incorporating performance evaluation through flight tests into the development process of FTV nozzles made it possible to identify problems that cannot be solved by wind tunnel tests or numerical analysis, and successfully accelerated the development cycle of the FTV system.

Academic Significance and Societal Importance of the Research Achievements

本研究の特色は,学術的には圧縮性ノズル流れの制御に関する流体工学と制御工学の融合およびその応用として位置づけられる。ノズル流れのFTVによる偏向特性について,偏向制御用二次流(入力)と偏向角(出力)の関係は,極めて非線形な流体現象に依存している。本研究は,この複雑なノズル流れに対して高度な制御を行うことによって,FTVを航空機の姿勢制御という実用レベルの応用へ引き上げるという点で,非常に独創的なものである。本研究によってFTV機構の開発サイクルが強化された結果,より高性能なFTV機構が短期間で実現されると予想され,FTV機構の実用化に向けて,本研究の工学的・社会的意義は大きい。
