Abstract:

This paper analyzes thedevelopmentstatus, existing technical problems and key technology ofthe conventional aircrafthigh-lift-system, and deduces and predicts the development trend of the high lift system technology for the future and next generation aircraft,based on the research of the advanced technology adopted by the high-lift-system for the typical aircraft of the latest generation, and combining the green aviation concept and the TRIZ (Theory of Inventive Problem Solving) dynamic evolution innovation theory. In particular, we analyze it from different levels such as the aircraft level, the system level, the critical partsand materials. Our conclusionprovidestechnical support and reference for subsequent civil aircraft high lift systems.

Key words: high lift system, intelligent wing, variable camber wing, differential control flap, electronic torque limiter, adaptive airfoil
