CCA 5月17日,中国首架装配鲨鳍小翼的空客A320飞机交付中国东方航空公司,空客“鲨鳍小翼”由此正式进入中国。这种看似鲨鱼鳍外形的翼梢装置引起了人们的兴趣。本文以图文并茂的形式讲解鲨鳍小翼的原理及空客翼梢装置的发展历程,以及其背后蕴藏的创新理念。空客公司是最早在民用喷气飞机上使用翼梢(也称翼尖)装置的先驱,从其最早的产品A300飞机开始就使用翼梢装置,至今已有数十年的历史。A300和A31 0两款机型均装配有被称为“镖形”小翼的翼梢装置。随后,空客把在A300、A310机型上所积累的经验应用在了A320系列飞机上。翼梢装置也陆续被安装到后来的A330、A340和A380机型上(形状和大小不尽相同),空客新一代远程宽体飞机A35XWB飞机也装有翼梢装置。
CCA On May 17, China’s first Airbus A320 aircraft equipped with shark finlets was delivered to China Eastern Airlines. Airbus “Sharkfin Wings” officially entered China. This seemingly shark fin shape of the wing tip device has aroused people’s interest. This article explains the principle of shark fins and the development history of Airbus wing tip device in the form of illustrations, and the innovative ideas behind it. Airbus pioneered the first wingtip (also known as wingtip) installation on commercial jet aircraft, and has been using wingtip devices from its earliest product, the A300, for decades. Both the A300 and A31 0 models are equipped with a wing tip known as a “dart” winglet. Subsequently, Airbus applied the experience accumulated on the A300 and A310 models to the A320 family of aircraft. The wingtips are also being installed on subsequent A330, A340 and A380 aircraft (varying in shape and size), and the Airbus Next Generation Long Range Wide Range Aircraft A35XWB aircraft are also equipped with wingtip devices.
