based on the datum that are distances between lasers and reflector on wingtip, thus the displacement of the wingtip is acquired by geometry calculating at any moment.
以激光器与安装反射镜的机翼顶端之间的测量距离数据为依据,得到机翼或机身上任意点的实时变形量。
even at the margins the collisions were devastating: the wingtip of the second plane grazed the78th floor sky lobby in the south tower instantly killing dozens of people waiting for elevators.
就连大楼的边边角角也遭到了彻底的破坏。第二架飞机的翼尖擦过了南楼78层,正在等电梯的几十人当即死亡。
the design of the winglet on the wingtip of a plane is a multifactor design, it is relatively complicated in the design of an aerofoil due to the influence of no lesser parameters.
飞机翼尖小翼设计是一个多因素设计,在机翼设计中比较复杂,影响参数较多。
