Recently, the installation of bearing rotor type 11 straight x-plane hovering flight a success, marked the avic helicopters have completed the assessment of 863 subject provisions of the state of installed, no bearing rotor by periodic breakthroughs. This has no bearing rotor ground resonance test three kinds of risk, to verify the 1.6 tons, 2 tons, 2.2 tons of three weight will not occur under the condition of the ground resonance of the conclusion, embodies the new rotor manipulation sensitive features. According to introducing, the test will be next to the ground long trial stage, the late according to the needs of the development of models applied to other types of research and development.
No rotor bearing technology is one of the important symbol of the levels of the fourth generation of helicopters, with high control efficacy, good agility, the advantages of high reliability, simple maintenance, is the main development direction of the rotor technology
