The results show that the efficiency of cascade would be more or less improved by the blade sweepforward, sweepback and bend, but the influence of them on the cascade flutter is various.

通過(guò)計(jì)算結(jié)果可以看出又黑又粗又长的欧美一区，前掠、后掠與彎曲或多或少可以提高葉柵的效率黄色视频在线观看官网，但對(duì)顫振特性的影響卻各有不同911国产在线。

Furthermore, the fan blade was stacked renewedly. And then, the influence of blade sweepforward, sweepback and bend on the cascade flutter was discussion.

本文還在三維風(fēng)扇葉片的基礎(chǔ)上對(duì)葉片重新積疊，討論了葉片前掠2020亚洲精品极品色在线、后掠以及彎曲對(duì)顫振特性的影響人人射人人摸人人干。

Further, each blade has, in the radial direction, a sweepforward wing portion situated on the boss side and exhibiting a positive advance ratio value, and a sweepback wing potion situated on the outer peripheral side of the blade and exhibiting a negative advance ratio value, with the arc length of each blade increasing from the boss side toward the outer peripheral side.

并且，葉片(4)具有輪轂側(cè)的前進(jìn)葉片部(2)和葉片的外周側(cè)的后退葉片部(3)美女被操黄色网站在线观看，前進(jìn)葉片部在半徑方向上具有前進(jìn)率為正的值与老妇岳性疯狂刺激小说，后退葉片部具有負(fù)的值。

A numerical simulation was conducted for a fixed-geometry two-dimensional mixed-compression supersonic inlet with sweepforward high-light and "X" type missile configuration. The results indicate:(1) The total pressure recovery declines with the rise of the free stream Mach number, while the mass flow ratio rises firstly and then declines when its maximum value is obtained at the design point.

針對(duì)一種定幾何二元倒置&X&型混壓式超聲速進(jìn)氣道開展了數(shù)值仿真研究六月亚洲色婷婷在线网站，結(jié)果表明：隨著來(lái)流馬赫數(shù)的增加特黄特硬特黄的黄片，進(jìn)氣道總壓恢復(fù)系數(shù)下降，而流量系數(shù)卻先上升日本欧美性爱，在設(shè)計(jì)點(diǎn)達(dá)到最大值后下降一级a做爱影院。

The effect of static aeroelastic distortion to the aerodynamic characteristic for a real high-aspect ratio sweepforward wing of composite material under different load statuses was analyzed. The integrated design method combined aerodynamic with structural was adopted in this analysis using associated computational fluid dynamics program FLUENT and computational structual dynamics program NASTRAN.
