查询词典 NACA

I decided to use urethane foam. I used 1" and 2" thick slabs of this foam, built up to fit the cover recess area and hot-melt glued together. I built up "shelves" as the plans recommended to support the foam, and then sanded the outside of the foam to match the shape of the fuselage bottom and the NACA air scoop.

我决定使用聚氨酯泡沫，我用1 "和2 "厚砖，这泡沫，建立起以适应封面休会面积和热熔粘在一起，我建立起来的"货架"作为计划的建议，支持泡沫，然后用砂纸外面的泡沫，以配合形状的机身底部和naca空气勺子。

In cases of 2-D flow problems, the external flows of cylinder and NACA 0012 airfoil were studied.

在二维流场算例中，我们计算圆柱及NACA 0012翼形流场问题。

For gas flow past cylinder, the characters of flow field in different Mach number and Knudsen number condition were investigated, and especially for low Knudsen number cases, the results were compared with calculating results of Euler's equation. It showed that they are correspondent by comparing the characters of bow shock and wake. The convergence rates of different high resolution and implicit schemes were also investigated. The convergence behavior of the implicit WENO scheme developed in this paper is better than others. For gas flow past NACA 0012 airfoil, the calculating results were compared with results of experiment. It showed that the results of WENO scheme are of higher accuracy for the case with angle of attack.

在圆柱流场时，我们探讨不同马赫数且不同纽森数时的流场特性，并在低纽森数时，与那维尔-史托克方程式的计算结果比较，我们比较了弓形震波及尾流附近的特性，其结果是相当符合的，同时我们也比较不同高解析隐式算则的收敛历程，从收敛历程图可得到，本文发展出来的隐式WENO算则有较佳的收敛效果；在NACA 0012翼形的流场中，我们将与实验结果做比较，发现利用WENO算则计算的结果，对於具有攻角的流场，亦有相当高的准确度。

It was at these places known as Langley, Ames, Dryden and Lewis that the NACA made some of the most important contributions to aviation.

就是在这些被人们称为兰利、艾姆斯、德莱顿和路易斯的地方，NACA做出了几项对航空事业最重要的贡献。

As a result of the NACA tests, Hiller initiated redesign of the X-2-235 to incorporate three-bladed coaxial rotors augmented by an aft-thrusting rear propeller.

由于测试结果中的NACA，希莱尔发起235重新设计的 X - 2 -纳入尾部，尾部螺旋桨一冲三同轴转子叶片的增强。

The NACA's spirit and innovative approach to research continues today, said Richard P.

NACA的精神和研究上的创新一直延续到今天。

The committee's name has been acronymed NACA.

该委员会的名称被缩合成NACA。

The clear NACA 0012 was used airfoil as a standard model to validate the numerical model that will be used in the following simulation.

工作中首先以未结冰的NACA 0012翼型为标准模型进行了数值验证计算，再以经过检验的方法计算结冰模型，并与结冰风洞试验数据进行了对比。

The fact that we had an NACA serves today as an inspiration to our modern aeronautics researchers, many of whom are working in the same facilities created in the heyday of the NACA.

在今天，我们曾有NACA的历史仍然对现在的航空研究人员以精神上的极大鼓舞。我们中的很多人都在与NACA全盛时期所创造的同样的设备条件下工作。

The flow field around NACA 0012 airfoil with software Fluent was simulated,to compare the correspondent aerodynamic performance variation before and after icing.

本文用FLUENT软件模拟了结冰后NACA 0012翼型周围流场的变化，并与结冰前NACA 0012翼型的气动性能进行了对比。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
