直升机技术发展现状与展望

Present Situation and Prospects of Helicopter Technology

简单回顾了直升机技术发展的历程和技术特点 ,介绍了直升机的技术进展 。

First, the history of helicopter technology is reviewed. Through analyzing the five features of a helicopter including the performance of the helicopter engine,the technology of the rotor system,the design technology of the helicopter structure,the architecture and characteristics of the avionics system,and the general performance of the helicopter,the main features of the development of the helicopter technology are summarized.Making these as the criteria,the development of the helicopter technology is divided into four generations the first time in the circle of helicopters in the world.At the same time,this paper provides the prospects of the development trends of the helicopter technology in the new century,such as the helicopter key system rotor system technology,the aerodynamics,the anti torque system,the avionics technology system,the helicopter dynamics,the helicopter simulation,the general performance of helicopters,etc.
