翼狀層
英文
pterygoid lamina-
The results show that : 1 ) though the water environment of nanyisan is more muddy than others, algal can still grow ; 2 ) the composition and rock type of the algal limestone are complex, the main rock types include lettuce - like stromatolites, algal reef, digitate stromatolies, wave - like stromatolites and so on ; 3 ) the deposits of algal limestones were formed in low - energy peritidal to subtidal high - energy environment of lakeshore slopes, sliding under the action of gravity and some other factors and become slump mixosedimentite layers ; 4 ) the physical property of algal limestones layers is better than others ; 5 ) the genetic development of the sediment decides that the single deposit is small, distributive and thin - layed
結果表明,南翼山藻灰巖沉積水體環境相對渾濁,但藻類仍能生長;該區藻灰巖巖石組成及類型復雜,主要的藻灰巖巖石類型有包心菜狀疊層石、藻礁、指狀疊層石、水平波狀疊層石等;其主要為濱岸斜坡上低能潮上環境至高能潮下環境形成的沉積體,在重力等因素的作用下產生滑動或滑塌形成的微生物成因的滑塌混積巖;巖層物性好於其它巖層;藻灰巖層的成因決定了該地區單個沉積體規模小、分散、層薄。Multi - gap - fowler - flap, while deflecting its rudders, simultaneously extends backwards by relatively large scope, which broaden the overall wing - camber and area, so that more additional lift could be attained through improving air - flow boundary layer
多縫富勒襟翼在襟翼舵面偏轉的同時發生較大幅度的後退,增加機翼整體彎度和機翼面積,通過縫隙氣流改善附面層狀況,因而得到加大的升力增量。This design has evolved from a previous version seen last year in japan, where the wave - like main profile formed part of a double - decker layout
這個設計是從去年在日本所見到的版本中演變而來的,當時主風翼型面是呈波浪形狀的,組成了一個雙層風翼的布局。In the examples we get some evolution curves, such as the growth rates and shape functions, which are used to analyze the stability problems for the boundary layers of the fuselage and the wing
算例給出了擾動幅值增長和形狀函數等演化曲線,並對機翼、機身的邊界層穩定性進行了分析和研究。3. the characteristics of boundary layer ' s transition, shape and separation are researched. the details as follows : ( l ) airfoil surface is turbulent boundary layer flows ; ( 2 ) velocity figure changed unsteady near the point of boundary layer separation due to randomicity of turbulent flow ; ( 3 ) the airfoil have better state of boundary layer separation and poor stall characteristics because of the upper surface of airfoil is flat
給出了該翼型的附面層特性:翼型表面基本為湍流附面層;在靠近附面層分離位置處,速度型形狀、特別是靠近翼型表面的底部速度型形狀變化不定,是湍流流動的隨機性所致;該翼型具有較好的附面層分離形態,但在失速迎角附近,附面層分離形態變化劇烈、失速特性差,是翼型上翼面形狀較為平坦所致。分享友人
