Abstract

This paper focuses on the special technical characteristics of helicopters

especially on the flight principle that differs from fixed-wing aircrafts

complex aerodynamics and structural dynamics

and demanding weight design

etc. Technical difficulties in aerodynamics

vibration and noise

ground/air resonance

crashworthy

safety

and weight control

as well as the underlying physical mechanisms and solutions are also expounded. Based on the analyses and study about development directions of helicopter technology in the world

it is proposed that future helicopter technology will focuses on high-speed

green

intelligent

unmanned

and safe flight. Combining the present situation and future trend of the helicopter technology development in China

three important directions for the future development of helicopter technology in China are put forward. These directions are advanced rotor blade and airfoil design

smart rotor

and high-speed helicopter. The scientific connotation and possible solutions of key technologies for the above directions are further proposed

which can hopefully provide a good idea for the future development of Chinese helicopter technology.
