风洞

The brothers are still in the wind tunnel test of their own design and manufacture a series of scale models, spent 7 years and cost more than 1000 U.S. dollars, and finally to create an aircraft with engine-driven.

兄弟俩还在风洞里试验了他们自己设计制造的一系列比例模型，花费7年多时间，耗资1000多美元，终于制造出一架用引擎驱动的飞机。

Some research methods, analysis software, design principles and criteria are developed for the analysis and design of ailerons and high-lift systems.

本文涉及计算流体力学、设计空气动力学、风洞特种实验等多个领域，形成了一种可用于舵面、增升装置的系统的研究方法、软件及设计准则和设计规律。

It was pointed that the study of downburst wind loads would provide the basis and guides for constructing the next wind tunnel emulating thunderstorm environment and downburst-resistant design of transmission tower-line systems; simultaneously it would give an important reference to both the design and implementation of wind-induced vibration control of transmission tower-line systems.

指出了对下击暴流风荷载的研究将为我国建造模拟雷暴风环境的新一代风洞实验室和输电塔线体系的抗下击暴流提供理论基础和设计指导，同时为输电塔线体系的风致振动控制设计与实现提供重要的参考。

ARA has performed both wind-tunnel tests and CFD computations for numerous Customer projects over the past 30 years. One such example is the investigation the interference effect of various boom support locations on the flow over a civil aircraft empennage; the accompanying figure shows the flow field in the region of the empennage, as computed by an Euler flow solver.

阿糖胞苷的表现都风洞试验和计算流体力学计算为众多客户项目在过去30年里，其中一个例子是，调查干扰的影响，各种蓬勃支持的地点，对流动的一个民用飞机尾翼；随行的数字显示流量外地在该地区的尾翼，作为计算一欧拉流求解。

Only a minimum of strut is exposed to the airstream, the remainder being shielded by fairings not attached to the balance

天平支杆只有很小一部分暴露在风洞气流中，而其余部分都用和天平不相连的风挡罩起来。

The fascias are said to be tuned in a wind tunnel, and combine to stretch the car more than seven inches in length.

该fascias被认为调整的风洞，并结合延伸汽车超过700英寸的长度。

Hot-humid climatic wind tunnel the paper introduced can simulate natural climate environmental elements namely solar radiation、air velocity、air temperature and humidity, according to the variant velocity of flow and regulation of infrared light, humidifier, heating and cooling facility.

热湿气候动态风洞实验台在具有可调低速风外，还通过设置红外灯、加热与制冷、加湿与除湿装置，初步实现了对室外自然气候要素太阳辐射、风速及温、湿度环境的模拟控制。

The obtained results were compared to data of testing the same model in a hot-shot wind-tunnel IT-302M at M_∞≈6 and 8,τ=100～120ms,Re_(1∞)=(1.3～1.8)×10~6,with boundary layer tripping on the surfaces of the inlet ramp and side compression wedges.

所获数据与同一模型在热射流风洞IT-302M实验马赫数M∞≈6，8，运行时间τ=100~120ms，雷诺数范围Re1∞=(1.3~1.8×106，进气道压缩面和侧压缩面进行了边界层转捩。
