| 摘 要： | 结合国外的相关研究工作,对新型无叶栅反推力装置的气动性能进行研究和分析,利用康达效应提高新型无叶栅反推力装置的工作效率。计算结果表明,利用康达效应可以使新型反推力装置的轴向反推力系数从0.175提高到0.36。此种反推力装置与常规叶栅式反推力装置相比,质量大大减轻,适合应用在大涵道比涡扇发动机上。

| Abstract: | Researched and analyzed the aerodynamic performance of a natural blockage thrust reverser,which is combined the research of other countries.Utilized the Coanda effect to enhance the work efficiency of the thrust reverser,the axial thrust reverser force efficiency is improved from 0.175 to 0.32 with the use of Coanda effect,which is lighter than the conventionality thrust reverser and can be used on the high bypass ratio engine. |
