随着直升机在各个领域的广泛应用,人们发现,常规的单旋翼带尾桨的直升机因尾桨造成的各种事故,占了直升机总事故的20%;尾桨的功率消耗达到了总功率的10%～15%。而共轴式直升机由于省去了尾桨系统,也就省去了这些麻烦。本文就共轴式直升机研制的可行性及其发展前景作一探讨。共轴式直升机与常规直升机共轴式直升机由于技术复杂,世界上能研制和生产的国家极少,而原苏联(现俄罗斯)的卡莫夫设计局进行共轴式直升机的研制已有50年的历史。海军使用的舰载直升机以共轴式为主。共轴式直升机与常规直升机比较有以下优点: 1.共轴式直升机由于没有尾桨系统,因而外形尺寸小,结构紧凑,主要的机体部件都紧凑地安排在全机重心
With the widespread use of helicopters in various fields, it was found that conventional single-rotor helicopters with tail rotor caused 20% of the total helicopter accidents due to tail rotor-induced accidents; the power consumption of the tail rotor reached a total power of 10% ~ 15%. The co-axial helicopter due to eliminating the tail rotor system, it eliminates the need for these troubles. This paper discusses the feasibility of coaxial helicopter development and its development prospects. Coaxial Helicopters and Conventional Helicopters Coaxial Helicopters Because of the complicated technology, there are only a few countries that can develop and produce in the world. For the past 50 years, the Karmov Design Bureau of the former Soviet Union (now Russia) History. The Navy’s carrier-based helicopters are mainly coaxial. Coaxial helicopters compared with conventional helicopters have the following advantages: 1. Coaxial helicopters because there is no tail rotor system, so the small size, compact structure, the main body parts are compactly arranged in the center of gravity
