autorotation
发音：/???ro?t??se??n/
英语范文：
Autorotation is a technique used in aviation to safely land an aircraft without using the wheels. It involves allowing the aircraft to rotate freely without any external control, and relies on the aircraft's inherent stability and aerodynamics to bring it to a safe stop on the ground.
在航空中，自旋技术是一种用于安全降落的技巧，无需使用轮子。它涉及让飞机自由旋转，无需任何外部控制，并依赖于飞机固有的稳定性和空气动力学，使其在地面安全停止。
英语作文音标和基础释义：
autorotation的英语作文音标为/???ro?t??se??n/，意为“自旋”。它是一种在航空中使用的技术，用于安全地降落飞机而无需使用轮子。该技术涉及让飞机自由旋转，无需任何外部控制，并依赖于飞机的内在稳定性和空气动力学，使其在地面安全停止。
此外，autorotation的基础释义为“自转或自行旋转”，在航空中，自旋技术通常用于直升机着陆时的稳定和安全。因此，autorotation也可以指直升机的自旋技术。
Autorotation
Autorotation is a fundamental concept in physics that refers to the rotation of an object without any external forces being applied. It is a natural phenomenon that we see in various contexts, from the rotation of the Earth to the spinning of a top.
In daily life, autorotation can be observed in many situations. For example, when a helicopter lands, the blades rotate freely without any external power source. Similarly, a spinning top continues to rotate due to its own inertia.
Autorotation can also be used in engineering applications. For instance, it is used in aircraft design to ensure that the wings and other components rotate freely and function properly. Understanding autorotation is crucial for ensuring the safe operation of aircraft.
In summary, autorotation is a fundamental concept in physics that refers to the rotation of an object without any external forces being applied. It is a natural phenomenon that we see in various contexts and is crucial for ensuring the safe operation of aircraft and other engineering applications.
Autorotation
Autorotation is a phenomenon that occurs when a object, such as a ball, falls freely without any external forces acting on it. As it falls, the object rotates continuously due to its own inertia. This rotation continues until it reaches the ground or encounters an external force that changes its direction of rotation.
Autorotation is commonly observed in nature, such as when a ball of sand falls freely from a height and rotates continuously. It is also used in various engineering applications, such as in the design of helicopter blades and airfoils.
In engineering, autorotation is often used to describe the behavior of rotating objects that are free to rotate without any external forces acting on them. It is also used to describe the behavior of aircraft and wind turbines that rely on their own momentum to generate lift and maintain flight or rotation.
Autorotation can be beneficial in certain situations. For example, it can help reduce the stress on rotating components and prolong their lifespan. However, it can also pose challenges in certain circumstances, such as when a rotating object encounters an obstacle or is subjected to strong winds or turbulence.
In conclusion, autorotation is a fundamental phenomenon that occurs in various contexts, from natural phenomena to engineering applications. Understanding its behavior and limitations is crucial for effective design and operation of rotating objects.
