大气紊流影响下飞艇水平面内运动分析
Analysis on Airship Movement in the Horizontal Plane In Atmospheric Turbulence
摘要
Abstract
Atmosphere disturbance is a key factor that affects the airship movement in horizontal direction.When studying the influence of atmospheric turbulence on the flight state of airship,many scholars have used Taylor frozen-field assumption,but it is not suitable for the low dynamic aircrafts,such as the airship,and it is necessary to consider the time change on impact of wind field.Firstly,the general description of the atmosphere disturbance is given,including the selections of related functions,spectrum properties,scale and intensity.Then the simulation model of airship dynamics in horizontal plane with disturbace wind field parameters is established.Lastly,the wind field disturbance is added to the airship dynamic model and the simulation analysis is accomplished on the basis of considering the wind field changing over time and taking no account of the effect of temporal variation.The simulation results indicate that the turbulence wind speed model considering the wind field changing over time can reflect the stochastic characteristics of airship response to turbulence truly.关键词
