旋翼是直升機的重要部件,也是直升機的象徵。先進的旋翼系統主要出自武裝直升機。這是因為武裝直升機戰術技術指標的高標準决定了它比普通直升機在氣動特性與氣動外形、旋翼拉力、槳轂結構等旋翼技術以及可維護性與安全性方面有更高的要求。武裝直升機的旋翼應當滿足性能高、振動小、噪音低、操縱功效大;並能承受大過載,高機動的氣動載荷以及抗彈傷能力强、裂痕擴散速度慢等要求。武裝直升機旋翼技術是綜合多門學科的高技術,主要包括:槳葉氣動特性及外形優化設計、新型旋翼結構動力學設
Rotor is an important part of the helicopter, but also a symbol of helicopters. Advanced rotor systems are mainly armed helicopters. This is because the high standard of military helicopter tactical and technical indicators determines that it has higher requirements than ordinary helicopters in terms of aerodynamic characteristics and aerodynamic shape, rotor tension, hub structure and other rotor technologies, as well as maintainability and safety. Armed helicopters rotor should meet the high performance, small vibration, low noise, large operating efficiency; and can withstand large overloading, high mobility of the aerodynamic load and anti-bullet-resistant ability, slow propagation of cracks and other requirements. Armed helicopter rotor technology is a comprehensive multi-disciplinary high-tech, including: aerodynamic characteristics and shape optimization design, a new type of rotor structure dynamics
