摘要：

Numerical　simulation　is　applied　to　study　internal　flow　structure　and　performance　of　counterflow　thrust　vectoring　nozzle　with　collar　length　in　zero　attack　angle　and　subsonic　conditions.　The　changes　of　thrust　vectoring　angle,　resultant　thrust　ratio　and　secondary　mass　flow　ratios　are　obtained.　Results　indicate　that　the　thrust　vectoring　angle　firstly　increases　and　then　decreases　with　increasing　suction　collar　length,　the　max　of　which　is　5.5o°　but　resultant　thrust　ratio　decreases,　and　its　range　is　0.76-0.78;During　the　procedure　of　increasing　suction　collar　length,　suction　flow　shifts　from　counterflow　to　coflow,　and　mass　flow　ratio　decreases.　©　(2013)　Trans　Tech　Publications,　Switzerland.
