Nf - 6 wind tunnel is a pressurizing, continuous, high - speed and return - flow aerofoil wind tunnel
Nf - 6風洞是一座由軸流式壓縮機驅動的增壓、連續、高速迴流式翼型風洞。Later in the war, the hurricane served admirably in north africa, burma, malta, and nearly every other theater in which the raf participated. the hurricane underwent many modifications during its life, resulting in many major variants, including the mk ia, with interchangeable wings housing eight 7. 7mm 0. 303in guns ; the mk iic, with a merlin xx engine ; the mk iid, a tankbuster with two 40mm anti - tank guns plus two 7. 7mm guns
颶風在它的發展過程中有過很多改進，發展出許多重要的變型，包括mk ia ，在翅膀上安裝8挺7 . 7 mm機槍「颶風」 mk iic型，裝備一臺「梅林」 mk xx發動機「颶風」 mk iid ，機翼上安裝兩挺7 . 7 mm機搶並且在機翼下吊掛兩門40 mm反坦克炮。Proceed from the angle of energy and taking considerations on interference factor and drag of airfoil profile, a kind of new typed calculation method on the design of vane air foil was put forward according to the vortex aerodynamics model of the rotor of wind turbines with horizontal axis
摘要根據水平軸風力機轉子的渦流氣動模型，從能量的角度入手，考慮干涉因子和翼型阻力，提出了葉片翼型設計的一種新型計算方法。Firstly, a representative wind and wave model, which could both simulate the main characteristics of wig over sea waves and be suitable for numerical calculation, is presented. the model completely considers the fully nonlinear effect of wave surface on the wavy air flow, separates the disturbance of wave surface from the wing - air wave interaction flow, and overcomes the numerical calculation difficulties due to the large difference of dimensions between wing and water waves
首先針對機翼在風浪中的非定常非線性氣動力問題，提出了一個既能夠反映風浪場主要特徵又適合於數值計算的風浪場模型，該模型完整地考慮了波浪表面對氣流場的全非線性影響，使波面對流場的擾動分離出來，消除了機翼和波浪幾何尺度上的巨大差異帶來的數值計算上的困難。At the end of the experiment, we reconstructed the subsystem of second air measuring, i. e. we used airfoil measuring equipment as a replacement of original equipment of flute pipe. we also demarcated the velocities of spouts of burner which can deal with correlative data, and which can provide some help for operation
最後又對監測系統二次風測量子系統進行改造，將原笛型管裝置修復為機翼測風裝置，對傳感器進行差壓標定;在爐內噴口處標定速度，將數據進行處理，提供給熱工控制顯示用，對運行調整提供了幫助。In chapter 4, the aeroelastic model of the whole test rig is first established by using jones ’ s approximation of theodorsen ’ s unsteady aerodynamics load. then, the numerical simulations and wind tunnel experiments for the sub - optimal flutter suppression of the airfoil model are presented
數值模擬和風洞實驗研究表明，以超聲電機為控制面作動器可以有效地抑制翼段模型的顫振，顫振臨界速度提高了13 . 4 % ，數值模擬和風洞實驗結果基本吻合。However, typically we fit just three and this can drop to as few as two for a low - downforce circuit, such as monza in italy
前翼的相對適應賽道的形狀並非空穴來風，而是通過一個名為「計算機氣流編輯器」的程序的運算后得來的，而這個運算系統同時和風洞模型的長時間測試緊密相關。分享友人
