题记:1959年春天一本杂志上的英国布莱克本公司飞机广告称:“NA.39领先一步”(NA.39is ahead)。布莱克本公司敢这么自信地吹嘘,是因为该公司研制 NA.39“掠夺者”(Buccaneer)时首次采用面积律来设计,因此使“掠夺者”飞机具备了低空高速的飞行能力。面积律是1952年美国空气动力学家惠特科姆首先发现的,它对于飞机减少波阻具有创造性的意义,面积律一经发现便很快被各国飞机设计者采用,布莱克本公司是较早采用这种先进设计的公司,因此,公司的广告暗示:公司新设计的海军攻击机天生就是个赢家。
Inscription: A magazine in the spring of 1959, the Blackburn, said: “NA.39 one step ahead” (NA.39 ahead). The reason why Blackburn brags so confidently is that for the first time the company designed the NA.39 Buccaneer by using the area law, so that the Predator aircraft is capable of flying at low altitude and high speed . The law of area was first discovered by American aerodynamicist Whitcomb in 1952. It was of great significance for the aircraft to reduce the drag. The law of area was quickly adopted by aircraft designers from all over the world and Blackburn was adopted earlier This advanced design company, therefore, the company’s advertising hinted: The company’s newly designed naval attack aircraft is inherently a winner.
