为了进一步提高民航旅客运输的安全性和减少飞机事故的伤亡率,对飞机座椅朝后这一新概念,从安全防护的改善方面进行了系统分析和定量的描述,建立了冲撞缓冲效果的估算模型,进行了相关的简单试验,并分析了空难幸存案例,从中得出结论,如果把飞机座椅朝后安装,可以主动地、大幅度地提高事故中对人体的防护能力,减少伤害率.另外,通过比较发现,由此带来的改善,并不减少飞机原有的性能指标,也不增加成本和维护的复杂性.最后提出了分级布置飞机客舱座椅的建议,以便保留部分朝前的座椅供一些有偏好的旅客进行选择,使所有的座椅安全性都有所提高,起到了系统优化的作用.此模型为新一代面向用户的飞机设计,提供了一个系统安全分析的基础.
In order to further improve the safety of passenger transportation and reduce the casualty rate of aircraft accidents, the paper systematically analyzes and quantitatively describes the new concept of airplane seat backwardness, and establishes the estimation of the impact cushioning effect Model, the related simple tests were conducted and the case of air crash survived was analyzed. It was concluded that if the airplane seat is installed backward, the protection ability on the human body in the accident can be greatly improved and the injury rate reduced. In addition, it is found by comparison that the resulting improvements do not reduce the original performance of the aircraft nor increase the cost and complexity of maintenance. Finally, a proposal is made to classify the aircraft cabin seats so as to retain part of the forward Seat for some preferred travelers to choose from to make all seat safety has improved, played the role of system optimization.This model for a new generation of user-oriented aircraft design provides a basis for system safety analysis .
