摘要
自适应机翼技术研究可分为通过机翼结构较小尺度变形的流动控制设计和较大尺度改变机翼几何构型的自适应结构设计两个范畴。改变机翼构型的自适应结构又包括可变前后缘结构、扭转机翼盒段结构、可变展弦比机翼结构这三种实现方式。根据目前自适应机翼技术的研究现状,归纳出了实现机翼自适应功能的两种途径,其中,采用智能材料结构进行驱动控制的研究代表了自适应机翼技术的发展趋势,而基于传统材料结构的自适应机翼技术则在现阶段更具有工程应用价值。
The research activities of adaptive wing technology can be classified into two catalogues, one is the flow control design by small scale deformation of wing structure, the other is the adaptive structure design by changing the geometric configuration of wing in large scale. The adaptive structure of altering the wing configuration in- volves three realization methods, variable leading/trailing edge structures, twisting wing box structure and variable aspect ratio wing. According to the up-to-date progress of adaptive wing technology, two realization approaches for adaptive capacity of wing are summarized, in which the study on actuation and control of wing deformation using smart materials and structures represent the development trend of adaptive wing, while the adaptive wing technology utilizing traditional materials and structures is more applicable in engineering at present.
