aerodynamics

aerodynamics的音标为[ˌeərəˈdæmɪnəstɪks]，基本翻译为“空气动力学”，速记技巧为：飞机飞行靠的是空气动力学。

Aerodynamics这个词源自希腊语，意为“空气动力学”。它的变化形式包括其复数形式“aerodynamics”和过去式与过去分词形式“aerodynamized”。这个词在英语中常与许多相关单词一起使用，例如“aircraft”、“aerodrome”、“aerodynamic”、“aerodynamically”等。

“Aircraft”意为飞机，其词源直接来自于aerodynamics，表示由空气动力学原理制造出来的机器。

“Aerodrome”意为机场，其词源来自于aerodynamics和aircraft，表示飞机起飞和降落的场所。

“Aerodynamic”意为空气动力学的，其词源来自于希腊语，表示与空气动力学相关的。

“Aerodynamically”意为空气动力学上，其词源来自于aerodynamics和adynamical，表示在空气动力学方面。

总的来说，这些单词都与空气动力学和飞行有关，是现代航空科学的重要组成部分。

常用短语：

1. aerodynamics of flight 飞行空气动力学

例句：

1. The design of an aircraft must take into account its aerodynamics to ensure safe flight.

2. The wings on this airplane generate a lot of lift, which helps it fly smoothly and efficiently.

3. The airflow over the car"s front end is turbulent, causing a lot of drag.

4. The designers of the new car have taken great care to ensure that it has an aerodynamic shape, which will help it to consume less fuel.

5. Aerodynamics plays a crucial role in the design of wind tunnels, which are used to test the aerodynamic performance of vehicles.

6. The development of new materials and manufacturing techniques has allowed designers to reduce aerodynamic drag and increase fuel efficiency.

英文小作文：

Airflow over an object in motion is influenced by its shape and speed, and the interaction between the air and the object determines its aerodynamic characteristics. From gliders to airplanes, wind tunnels to cars, aerodynamics plays a vital role in our daily lives. Aerodynamic drag, for example, affects how far an object can travel before needing to land or refuel, while efficient aerodynamics can reduce fuel consumption and emissions, leading to a greener future. As we continue to develop new technologies and materials, we will continue to rely on aerodynamics to improve our lives and the environment in which we live.
