直升机可以垂直起落,可以前飞、后飞、侧飞、悬停,在战场上是极其有用的工具。但是在日益激烈的现代战场上,直升机的飞行速度太低,直接影响其战场上的生存能力。美国的 V-22独辟蹊径,采用倾转旋翼的设计,将直升机的特殊能力与固定翼飞机的快速结合在一起,“鱼与熊掌”兼得。而在我国,高效快速的直升机更是十分缺乏,特别是在这次抗震救灾的过程中,更显露了空中运输力量的薄弱。
Helicopter can vertical landing, can fly before, after the fly, side fly, hover, on the battlefield is an extremely useful tool. However, in the increasingly fierce modern battlefield, the flying speed of helicopters is too low, which directly affects the survivability on the battlefield. The United States V-22 unique, using tilt rotor design, the special ability of helicopters and fixed-wing aircraft combined quickly, “fish and bear’s paw ” have both. In our country, efficient and rapid helicopters are still very scarce, especially in the process of earthquake relief, but also revealed the weakness of air transport.
