倾转旋翼机风洞试验综述

Tiltrotor aircraft is a significant trend in the development of the next generation of rotorcraft. It integrates the advantages of rotorcraft and fixed-wing aircraft，but also introduce more complex problems in terms of aerodynamics，structural dynamics，flight dynamics，and aeroelastic coupling. The wind tunnel experiment is an important technical method to understand and investigate the key aerodynamic，structural，and flight issues of tiltrotors. This paper give a comprehensive overview of a large number of wind tunnel tests in the development process of tiltrotor aircraft in China and other countries，and provides various types of test simulation criteria，equipment and facilities，typical results，and main conclusions of tests for tiltrotor aircraft rotors and corresponding airfoils，rotor/wing aerodynamic interference，ro⁃ tor/wing aeroelastic stability，virtual flight，etc. Considering the research and development requirements，this paper also proposes suggestions for the development of wind tunnel testing technology for tiltrotor aircraft in China.
