基于结构能力的水上飞机适海性研究

适海性是水上飞机的重要技术指标,结构能力是影响水上飞机适海性的关键因素。研究基于结构能力的水上飞机适海性评估。阐述水上飞机结构能力的重要表征量着水载荷系数的计算原理、公式、影响参数。介绍水上飞机抗浪高度计算方法和流程,给出考虑不同参数影响的特征系数。以某大型水陆两栖飞机工程设计为例,进行断阶着水水面反作用载荷系数计算和适海性评估及变参数分析。提出2种提高适海性的思路。该研究已在型号研制中应用,并可为其他水上飞机或水陆两栖飞机的设计提供参考。

Seaworthiness is an important technical index of seaplane,and structural capability is the key factor affecting seaplane seaworthiness.The seaworthiness evaluation of seaplane based on structural capability is studied.The calculation principle,formula and influence parameters of the water landing load factor,which is an important characteristic of seaplane structural capacity,is introduced.The calculating method and process of wave height that the seaplane must overcome are introduced,and the characteristic coefficients considering the influence of different parameters are given.Taking the engineering design of a large amphibious aircraft as an example,the calculation of the water reaction load factor,the assessment of seaworthiness and the analysis of variable parameters are carried out.Two ways to improve seaworthiness are presented.The study has been applied in aircraft project development,and can provide reference for the design of other seaplanes or amphibious aircraft.
