摘要
适坠性是对轻型飞机设计提出的新要求。空间、约束、环境、能量控制和坠机后的因素是适坠性设计的主要要求。为了提高飞机的适坠性,必须对飞机结构进行相应的改进。本文在介绍飞机适坠性的本质和基本要求的基础上,列举了当前一些结构设计在适坠性方面存在的不足,总结了在轻型飞机上采用低置的发动机架、去除直角的防火墙、吸能地板、柔性座椅和加强的前机身等改进方案对提高飞机适坠性的效果和原理。
The crashworthiness is a new technical need for light aircraft design. The fundamentals of the crashworthiness design include container, restrain, environment, energy management, and post-crash factors. To improve the crashworthiness, the airframe must be modified. Based on the nature and general demand of crashworthiness, defects in the crashworthiness of some light aircrafts are presented. And this paper introduces the modifications including a low engine mount, a nonscooping firewall, an energy absorbing floor, and flexible seats.
