...在为我们的小云雀作最后的全身检测,细心观察,这台基本型云雀还是蛮可爱的,还有一个非常浪漫的名字——WOW风之翼(WING OF WIND),美中不足是排量仅658CC,装备了贵航开发的EWPI多点电喷燃油控制系统的wow能否真的车如其名,象风中之翼,还要看等一会儿的上路...

With high-speed wind tests of scale models under way, the blended wing could take flight before 2020.
目前,等比例模型的高速风洞测试正在进行中,预计混合机翼能在2020年前起飞。
Vibrating in the wind, the bristles create some drag. But they also reduce the wing's slipstream, an area of low-pressure turbulence that pulls back on the wing, and hence reduce drag.
风中振动时,刷毛会产生反作用力,但同时它也可以减少机翼滑流,产生一个低气压乱流,机翼上形成回力,因而减小阻力。
This illustrates the initial "pop" of the lower wing. the Wind dictates how hard this input is and how fast the next input occurs.
这说明了初始作用在下翼上的弹拉的效果。风力决定了动作的力度和下一个动作的时机。
