摘　　要：为了探索在超跨音速下具有优良启动特性的叶型,以某跨音速叶型为例,对吸力面作了“凹”形设计,分析比较了改型前后叶栅气动性能的变化,为叶型设计提供一种思路。For investigating the profile that has advanced startup characteristic with the supersonic and transonic conditions, the present paper design the suction surface as the ＂concave＂ type based on a transonic profile, and analysis the changing of the aerodynamic characteristic of the original and the remodeled cascades, so gives a thoughtway for designing the blade profiles.

关 键 词：“凹”形 跨音速 叶型
