    摘要:

    变体飞机能够改变自身外形适应不同的飞行状态,提高飞行性能,其设计涉及气动、材料、结构等多个学科。本文采用零泊松比蜂窝结构的材料作为柔性蒙皮,设计了一种具备机翼参考面积不因弯度改变而缩减的特点的机翼后缘无缝偏转机构,研究了变体机翼后缘机构多学科设计与优化方法。优化结果表明,优化后的机翼巡航和起降状态都具备良好的气动性能,不但柔性蒙皮可产生大尺度拉伸变形,而且后缘结构均能满足刚度、强度等性能指标,同时机翼结构质量相比初始设计减轻了18%。文中研究的变体机翼多学科优化设计方法,能够快速有效地完成变体机翼无缝偏转后缘优化设计。

    Abstract:

    Morphing aircraft could change its shape to adapt to the different flight conditions and improve the flight performance. Morphing aircraft design involves aerodynamics, materials, structure and other disciplines. With zero Poisson’s ratio honeycomb structure material as the flexible skin, a seamless deflection trailing edge of wing is designed. The reference area of the wing does not decrease due to changes in camber. And the multidisciplinary design optimization of the morphing wing trailing edge is studied. The optimization results show that the optimized wing provides good aerodynamic performances under cruise and takeoff and landing conditions. The flexible skin can produce a large-scale tensile deformation, the trailing edge structure of wing meets the stiffness, strength and other performance requirements, and the weight of the wing structure is reduced by 18% compared with the initial design. The studied multidisciplinary design and optimization method of morphing wing can quickly and effectively complete the seamless deflection trailing edge of wing design and optimization.
