舰载机滑跃起飞动力学与运动学特性

Dynamics and kinematics characteristics of carrier-based aircraft ski-jump take-off

首先介绍了舰载机滑跃起飞技术的概念、现状及发展趋势。然后基于作者在型号研制及试验试飞方面的工作经验,从滑跃起飞过程中的舰载机本体,包括起落架缓冲器、轮胎在内的多体系统运动学与动力学特性出发,分别对影响舰载机滑跃起飞动力学和运动学特性的若干关键因素进行了讨论,这些因素主要包括甲板风场、发动机、起落架、操纵系统和重量特性等。最后通过定性和定量的对比分析结果,从飞机设计与使用两个维度识别出滑跃起飞设计所需重点考虑的影响因素、动力学与运动学成因以及相关设计指标,对滑跃起飞动力学与运动学特性进行了全面的探讨与深层认知。可为从事相关型号的设计、试验及使用的技术人员提供参考。

This article introduces the concepts,current situation and development trend of ski-jump take-off of carrier-based aircrafts.Then,based on the authors’experience of model development and flight tests,the key factors that affect the dynamics and kinematics in ski-jump take-off are discussed after an analysis of the kinematics and dynamics of the aircraft airframe,landing gear buffer,and tire in the process.These factors are found to be deck wind,engine,landing gear,control system,and weight characteristics.Finally,through a comparison of qualitative and quantitative analysis results,the key influencing factors and design indicators involved in the design of ski-jump take-off are summarized,and a comprehensive discussion of the dynamics and kinematics characteristics of ski-jump take-off are conducted.This article can provide references for designing,testing and using of carrier-based aircrafts.
