翼柵 的英文怎麼說
中文拼音 [yìzhà]
翼柵
英文
airfoil cascade-
The results show that the frame of the grid fin has the greatest effect on the grid fin drag characteristics, reducing the drag levels and enhancing the lift - drag ratio for grid fin may be obtained by selecting appropriate frame cross - section shape and thickness of grid fin
計算結果顯示，格柵翼的幾何結構參數對格柵翼的氣動力特性影響很大，格柵翼的邊框剖面形狀和厚度對格柵翼的阻力影響最大，所以選擇合適的邊框厚度和剖面形狀可以有效地減少格柵翼的阻力，提高陞阻比。This paper studies the effect on aerodynamic characteristics of the grid fin geometry by choosing different cross - section shape and thickness outer frame, changing the thickness of internal fins and the density of internal honeycomb, comparing the datas obtained from the corresponding wind tunnel tests
模擬了格柵翼的邊框剖面形狀和邊框厚度以及格柵莖厚度、蜂窩疏密度對格柵翼氣動力特性的影響，並把計算結果與實驗結果進行了比較。Boundary element analysis on the flow field and pressure field of flow around cascades with small angle of attack
小沖角翼柵繞流問題流場和壓力場的邊界元分析When escape system is activated, the grille wings at the upper fairing will open, supporting frame will pick up the orbit and returning modules, the lock between the returning and propelling modules will release, the lock between the upper and lower fairings will release, escape rocket will be ignited and finally pull the escape flight vehicle away from the rocket
該系統由逃逸塔和上部整流罩組成，逃逸系統加上飛船的軌道艙和返回艙構成逃逸飛行器。當需要逃逸時，上部整流罩上的柵格翼打開，支撐機構夾住飛船軌道艙和返回艙，然後返回艙與推進艙解鎖上下整流罩解鎖逃逸發動機點火，逃逸飛行器飛離運載火箭。The width to width ratio of grid fin was an important parameter influencing the aerodynamics of grid fins
摘要格寬翼弦比是影響柵格翼氣動特性的一個重要幾何參數。In order to research the aerodynamic characteristics of grid fins effected by width to length ratio, the grid fins of three hight to width ratios were adapted in wind tunnel experiments at subsonic, transonic and supersonic speeds
為研究它對柵格翼氣動特性的影響規律，本研究採用風洞實驗的方法對3種不同格寬翼弦比的柵格翼在亞、跨、超聲速3個馬赫數下進行了氣動特性的研究。分享友人
