中文摘要：

民用飞机地面漂浮性是评估飞机-机场相容性的一个重要指标,其直接影响到飞机设计参数选择以及地面适应性的优劣。在总体概念设计阶段就必须对飞机的漂浮性能进行分析评估,从而选择恰当的飞机参数。对民用飞机在刚性道面和柔性道面上漂浮性分析方法做了简要说明,并针对国际民用航空组织所推广使用的ACN/PCN（飞机分类号/机场分类号）方法进行了详细分析研究,在此基础上,开发出了飞机地面漂浮性分析软件。通过直接输入飞机相关参数可以快速准确地计算出飞机分类号ACN值。可以有效地对飞机地面漂浮性进行评估和优化,从而解决了用手工方式评估飞机地面漂浮性时的繁琐及不准确,并降低了对从事飞机地面漂浮性计算的人员要求。

英文摘要：

Civil aircraft ground flotation is an important evaluation indicator of aircraft-airport compatibility,which affects the aircraft design parameters selection and the pros and cons of the ground adaptability directly.In the general conceptual design stage,the analysis and evaluation of the aircraft flotation must be done to select the appropriate parameters of the aircraft.This paper briefly describes the analysis methods of civil aircraft floating in the rigid pavement and flexible pavement,and carried out a detailed analysis and research for the ACN / PCN,the aircraft and airport′s class number method,that is promoted by International Civil Aviation Organization and developed a aircraft ground flotation analysis software on that base.Inputting the relevant aircraft parameters directly,it can calculate the value the class number of aircraft,ACN,quickly and accurately.The software can effectively evaluate and optimize aircraft ground flotation,thus solve the problem of the complication and inaccuracy caused by evaluating the aircraft ground flotation by hand.In addition,it also reduces the demand for the personnel engaged in it.
