Outline of Final Research Achievements

Effects of operating conditions and design parameters such as combustor sizes on propagation modes of rotating detonation waves (RDWs) and thrust have been systematically studied in order to establish universal design principles of rotating detonation engines. The experimental results show that there exits a critical propellant mass flux rate at which the wave number of RDWs increases. The larger combustor exhibits more RDWs in the combustion chamber and increase in the operating frequency under the condition that the propellant mass flux rate is kept constant. In addition, decrease in the width of the annular combustion chamber gives higher thrust, which is due to higher pressure in the combustion chamber.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、様々な混合気に対する回転デトネーション波(RDW)の伝播モードと推進剤質量流束の関係が明らかになり、異なるサイズの燃焼器における回転デトネーション波の挙動が予測可能となった。また、同一サイズの燃焼器を用いて同一の推進剤質量流量を供給しても、燃焼室幅によって推力が異なることが明らかになり、重要な回転デトネーションエンジン設計指針が得られた。
