轻质夹层多功能结构一体化设计

INTEGRATED DESIGN OF LIGHTWEIGHT MULTIFUNCTIONAL SANDWICH STRUCTURES

对于飞行器,减轻结构重量,提高有效载荷是设计者追求的永恒主题.飞行器通常处于较为特殊和复杂的环境下,因此除需要考虑结构的承载能力外,还应兼顾一种或多种功能.本文概述了集承载与热控、防热、电子、隐身、吸能、作动、储能、阻尼等多功能特性于一体的轻质夹层多功能结构研究成果,汇总了轻质夹层多功能结构在卫星、无人机、高超声速飞行器等领域的发展情况.最后,对轻质点阵多功能结构的发展前景进行了展望.

Reducing the structural weight and enhancing the effective load of all kinds of aircrafts are the eternal subjects for designers all long. As regards that the air vehicles are usually in a special and complex service environment, one or more functions should be also given consideration except to the carrying capacity of the structures is designed. This article presents a comprehensive review on integrated design of lightweight multifunctional sandwich structures, which can realize loading and other multifunction, such as thermal control, heat protection, electron effect, stealth technique, energy absorption, actuating, energy storage, damping etc. This paper pools all those studies of lightweight multifunctional sandwich structures in the field of satellites, unmanned air vehicles and hypersonic space vehicles and so on. At last, the development tendency of lightweight lattice truss multifunctional structures is pointed out.
