摘　　要：为了提高开口V形跑道的运行安全及效率,对开口V形跑道的尾涡遭遇及受力模型进行研究。结合天府机场跑道构型及运行模式,考虑侧风对尾涡位置的影响,分析后机遭遇前机尾涡的方式。同时,引入飞机颠簸强度作为安全指标,建立后机遭遇尾涡的坐标系,给出后机承受尾涡的受力计算公式。并以前机为A340-600使用天府机场东一跑道起飞及进近着陆、后机为A320-200使用北一跑道起飞为例,对后机承受尾涡最大力的位置和最大过载进行仿真。结果表明,使用东一跑道向南进近着陆的航空器与北一跑道起飞的航空器之间不存在尾涡影响。其结论与以相关规章及飞行程序为基础对天府机场开口V形跑道尾涡的影响进行分析所得出的结论相同,验证了受力模型的准确性。This paper intends to study the wake vortex encounter and the force model of the open V-type runway so as to improve the safety and efficiency of the said V-type runway.In accordance with the runway structure and the operation mode of the Tianfu Airport,it is often the case to determine the way of the wake aircraft encountering the front wake vortex by considering the influence of the crosswind on the position of the wake vortex.However,for the said purpose,it is also necessary to introduce the aircraft turbulence intensity as a safety indicator according to the way the rear aircraft encounters the aircraft wake vortex in its front.At the same time,the coordinate system of the wake vortex has to be set up according to the given calculation formula of the wake vortex force.For instance,by taking the front aircraft as the A340-600 that tries to take-off and then land by using the East 1 Runway of the same airport,whereas the rear aircraft,the A320-200,has to take-off by using the North 1 Runway of the same airport.In doing so,the position of the wake under the maximum force has first of all to be simulated and analyzed.And,next,according to the different atmospheric environment conditions,it is also necessary to determine the position of the rear aircraft which bears the maximum force of the wake vortex,i.e.the maximum overload.And,naturally,it is also necessary to analyze the safety of the rear aircraft by considering the pilot’s reacting time by choosing the appropriate indicators.The results the above mentioned events that take place simultaneously would mean that there is no wake effect between the aircraft that uses the East 1 runway to approach and the other aircraft that may take off from the North 1 runway.The conclusions can be taken are likely the same as those based on the relevant regulations and flight procedures,which remain to be analyzed as to the influence of the V-type runway wake vortex at the Tianfu Airport.The accuracy of the force model can thus be verified.
