简介:摘要:随着航空技术的发展,在日常工作中,A320NEO飞机越来越常见,所以它一定有独特的优势。都说A320NEO飞机节油,论文从其和A320CEO飞机的某些参数比较来分析A320NEO飞机的优点以及其节油的原因。
简介:在装载的biaxial下面的液体水晶弹性体(LCE)的thermo-order-mechanical行为在这份报纸被学习。为非线性的有弹性的问题的反的方法被强加拉长到薄矩形的样品的biaxial利用。新古典的有弹性的精力和Landau-deGennesnematic被使用免费精力。在飞机压力假设下面,组成的方程被导出。由于装载的强加的biaxial导致的液体晶体分子的可能的重取向,装载轴将有最大的有效主要紧张的非线性的压力紧张关系能有不同表情取决于的在里面飞机。并且免费精力是多好非凸的潜在的功能。是由一些典型装载路径出现,LCE样品将展出各向异性的非线性的有弹性的行为,只要装载没导致液体水晶分子的重取向。当这确实发生了时,压力跳能由于输稳定性为死了的装载发生。
