查询词典 aerodynamic

To reveal aft end internal flow feature of a solid rocket motor with submerged nozzle, a two dimension cold flow test model with rectangular channel was designed The cold gas simulation was based on geometric similarity and aerodynamic analogy Mean and fluctuating velocity field was measured using phase doppler particle analyzer It showed that the flow separates at upstream of the submerged nozzle and reattaches on the tip of the nozzle nose A relatively steady recirculation zone formed in...

为了揭示含潜入喷管的固体火箭发动机尾部流动特征，按照几何相近和气动相似原则设计了通道为矩形的二维冷流实验模型，利用相位多普勒粒子分析仪对燃烧室尾部气流的时均速度和湍流脉动速度进行了测量。实验结果表明气流在潜入喷管入口上游发生分离，再附点位于喷管前端部外侧，背壁空腔内形成一个较为稳定的回流区，流场的轴向和横向湍流强度都比较大

应用RNGk-ε湍流模型对国产某型号轿车车身进行了外围流场数值模拟，针对高速条件下轿车尾部升力随之增加、操纵稳定性下降的特点，设计了一阶和二阶尾翼。

On the numerical simulation platform of aerodynamic heating for aircraft with complicated shape developed by our institute, we realized the visualization of two and three-dimension data fields of structured grid and unstructured grid, drawing the nephograms and contours of scalar field and vector plots streamline of vector fields, and show the temperature distribution of structure fields as well.

VISC是利用现代计算机强大的图形功能把科学计算中产生的数字信息转变为直观的、以图像或图形信息表示的、随时间和空间变化的物理现象或物理量，从而形象地反映数据场量的分布情况，并提供交互处理工具与手段。

Aircraft-type missile,aircraft-like missile, aircraft-shaped missile, air-supported missile, aerodynamic missile, cruise missile, pilotless missile, wing-borne missile, winged missile.

c &飞航导弹由英文& cruise missile &而来，是指在飞行过程中与地面保持一定高度、以巡航速度飞行的有翼式导弹，有时也称为巡航导弹。按照国内的分类习惯，巡航导弹中收入的是射程大于500 km的远程飞航导弹&。

Onboard TV shots showed the upper profile bending downwards at speed, opening up a gap between the wing element and the nose cone, prompting many to question whether this constituted a moveable - and hence illegal - aerodynamic device.

车载电视镜头的画面显示，上层风翼在高速状态下向下弯曲，风翼和鼻锥之间就会出现了一个缺口，因此很多人都怀疑，这是不是已经构成了可移动的空气动力学部件，因此属于违规的。

In addition, it's computed that how the aerodynamic force of flexible flapping-wing changes with flap parameters, such as flap angle, flap frequency, and so on. The computed results explained why bird wing have different flap motions in different phases of flight, and provide theory for future design work of flapping-wing MAV.

此外，本文还模拟计算了时柔性扑翼气动力随扑动角、扑动倾角等参数变化的情况，从而从气动的角度解释了飞鸟在不同飞行阶段的扑翼规律，并为柔性扑翼飞行器的设计提供了理论依据。
