Fluent was used to simulate the flowfield of 3 - d complex flowfield of rocket - missile with wings and empennages induced by the interaction by base jet and the flow around the body . in order to study the complex flow problem above , numerical simulations were performed under the following kinds of flow conditions : ( l ) flow of rocket - missile with wings disturbed by supersonic upstream flow . ( 2 ) flow of rocket - missile with wings disturbed by supersonic upstream flow with attack angle 為了研究以上復雜流場考慮了如下幾種情況: ( 1 )帶彈翼彈箭超音速無攻角繞流; ( 2 )帶彈翼彈箭超音速有攻角繞流; ( 3 )帶彈翼彈箭亞音速有攻角繞流; ( 4 )帶彈翼彈箭超音速有攻角繞流噴流干擾; ( 5 )帶彈翼尾翼彈箭超音速有攻角繞流; ( 6 )帶彈翼尾翼彈箭超音速有攻角繞流噴流干擾。

The 3 - d complex flowfield of rocket - missile with wings and empennages induced by the interaction between by base jet and the flow around the body has been numerically simulated . the main work is as follows : first , the gordon - mcbride program was developed to make it more friendly and efficient to the users 本文對帶彈翼/尾翼彈箭的三維噴流繞流復雜流場進行了數值模擬,其主要研究內容有:首先,對gordon - mcbride火箭程序作了改進,使改進后的軟件具有了非常友好的人機交互界面。

Many factors were considered in the algorithm such as the helicopter nonlinear flight dynamic model , the time delay of rotor wake , the air compressibility at advancing blade , the stall of retreating blade , the unsteady flapping motion of rotor blades and the aerodynamic interaction among rotor , fuselage , tail rotor and empennage 根據這一方法可以確定為完成直升機機動飛行所需的駕駛員操縱輸入及直升機的飛行速度、角速度和飛行姿態的變化歷程。

The active vibration control aimed at aircraft empennage has huge practical values in the aspects of adding the fatigue life of vertical tail , increasing the capability and availability of the aircraft , reducing the through - life - support costs and so on 飛行器垂直尾翼的振動主動控制對于提高尾翼的疲勞壽命、飛行器的機動性以及減小飛行器的維護成本具有較大的實際意義。

This transition has enabled aidc to aggressively pursue extensive business opportunities with foreign aerospace manufacturers , on programs such as boeing b - 717 - 200 empennage , bombardier bd - 100 empennage , alenia 本指導小組下設航空工業組航空服務業組國防工業組及綜合業務組,其任務如下:

Finally , the seven - hole probe experiment was made on the wake flow of the fuselage with empennage and engine cabins 并應用微型總壓管進行了后體的邊界層測量實驗,得到了邊界層平均速度分布。
