摘　　要：为了对燃气舵控制力的影响因素进行分析,运用FLUENT软件对不同影响因素条件下燃气舵的尾流场进行数值模拟。计算结果表明:随着舵片与喷管端面间的间隙减小,燃气舵产生的控制力越大;在一定的切入角度范围内,随着舵片切入角度的加大,燃气舵产生的控制力增大,但当切入角度大于10. 5°时,燃气舵产生的控制力开始减小;在一定的反射板高度范围内,随着反射板高度的增加,燃气舵产生的控制力增大,但当反射板高度大于8 mm时,燃气舵产生的控制力会急剧减小。计算分析结果对燃气舵的工程设计具有重要意义。In order to analyze the influence factors of jet vane control,FLUENT software was used to simulate the flow field of jet vane under different influence factors.The calculated results showed that with the gap between the rudder and the nozzle decreased,the jet vane control increased;within a certain range of cut angle,the jet vane control increased with the increase of the rudder angle,but when the angle was greater than 10.5°,the jet vane control decreased;within a certain range of baffle height,with the increase of baffle height,jet vane control increased,but when the baffle height is greater than 8 mm,the jet vane control would decrease sharply.The calculation results were of great significance for the design of jet vane.
