查询词典 sweepforward

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.

通过计算结果可以看出，前掠、后掠与弯曲或多或少可以提高叶栅的效率，但对颤振特性的影响却各有不同。

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

本文还在三维风扇叶片的基础上对叶片重新积叠，讨论了叶片前掠、后掠以及弯曲对颤振特性的影响。

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，叶片(4)具有轮毂侧的前进叶片部(2)和叶片的外周侧的后退叶片部(3)，前进叶片部在半径方向上具有前进率为正的值，后退叶片部具有负的值。

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.

针对一种定几何二元倒置&X&型混压式超声速进气道开展了数值仿真研究，结果表明：随着来流马赫数的增加，进气道总压恢复系数下降，而流量系数却先上升，在设计点达到最大值后下降。

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.
