瑞典皇家理工学院(KTH)的研究人员正在开发一种装置,使用电风来降低卡车的燃油消耗。重型卡车在高速公路上长距离高速行驶时,空气阻力会增加。KTH的研究人员发现,飞机也有类似的问题。例如,当飞机起飞时,越来越大的攻角使得翼尖附近机翼下表面的空气会绕流到上表面,形成翼尖涡。通过安装翼尖小翼,可 Researchers at Royal Institute of Technology in Sweden (KTH) are developing a device that uses electric wind to reduce truck fuel consumption. Heavy truck on the highway long-distance high-speed driving, the air resistance will increase. Researchers at KTH have found that planes have similar problems. For example, as the aircraft takes off, the larger the angle of attack, the more airborne the air underneath the airfoil near the wingtip will flow to the upper surface, creating a wingtip vortex. Can be installed by installing wingtips
