补充资料:边条
      飞机机身头部两侧或机翼根部前缘向前延伸的水平狭长翼片。前者称为机身边条,用来控制机身头部在大迎角时的涡流,改善飞机的横侧稳定性;后者称为机翼边条。边条通常指机翼边条,主要用在展弦比为3~4的薄机翼上。它可改善机翼在大迎角时的气动特性,特别是升力特性。边条好像一个前缘尖锐、大后掠角(70°~80°)的细长三角翼。 在大迎角下, 在边条的前缘将形成强烈的涡流,它向后流经机翼的上方时,能延缓机翼的气流分离,增加机翼升力,改善飞机在大迎角时的稳定性。机翼边条能提高飞机的机动性,在超音速歼击机上得到广泛应用。边条的缺点是使飞机在小迎角下的阻力增加。但适当设计边条的形状,使边条带有一定曲度,可减小这种不利影响。
