气动力学中的一种物理现象，流体在流体物体表面接触时，由于流体的粘性和物体表面光滑，流体被物体表面吸引，在物体表面形成附着层，使物体表面附近的流体的速度减小（宏观表现就是压强增大）
^[2]^。该现象被广泛应用于飞机的表面飞行器设计、火箭设计、船舶设计、流体管道设计、化妆品等领域^[1]^。
气动附着是指高速流动中，流体质点与相邻流体质点相互接近并发生粘接的现象。被粘着的流体质点在接触处变形相互紧密靠拢，此处的流动边界层相互融合，使边界层外与边界层内流体相互交换，形成突扩边界层。在流动的整个流场中，附着层内与主流方向垂直方向上存在速度梯度变化，形成涡旋，产生动压，因此附着层内总压也增加，总压随粘着速度的提高而增加^[4]^。
Title: Aerostatics: The Role of Air Pressure in Aerospace Engineering
Aerostatics is the branch of fluid mechanics that studies the motion of air or other gases under certain pressures. It is essential in aerospace engineering, where air pressure and density play a crucial role in the design and operation of aircraft and other aerial vehicles.
Firstly, aerostatics deals with the behaviour of gases under pressure. It involves understanding how air molecules behave under various pressures, and how this affects the overall density of the gas. Understanding this relationship is crucial in designing aircraft that can operate efficiently at different altitudes and conditions.
Secondly, aerostatics is closely related to aerodynamics, which studies the motion of air around objects. Understanding aerodynamics and aerostatics together allows engineers to design aircraft that are both efficient and safe. For instance, optimizing the shape and surface area of an aircraft can significantly reduce drag, increasing its fuel efficiency and range.
Moreover, aerostatics has a significant impact on aircraft design and construction. High-pressure air systems are commonly used in aircraft to power systems such as hydraulic actuators and air brakes. Understanding how these systems work and how they are affected by aerostatic forces is crucial for ensuring their safe and reliable operation.
Furthermore, aerostatics has a profound impact on aircraft performance and flight control. For instance, high-pressure air systems can be used to control altitude and speed, while understanding aerostatic forces can help engineers design aircraft that are more stable in flight. Additionally, understanding aerostatic forces can help engineers design aircraft that are more fuel-efficient and environmentally friendly.
In conclusion, aerostatics is an essential aspect of aerospace engineering that impacts the design, construction, and operation of aircraft. Understanding this branch of fluid mechanics is crucial for ensuring the safe, reliable, and efficient operation of aerial vehicles. By harnessing the power of aerostatics, engineers can design aircraft that are not only efficient but also environmentally friendly, sustainable, and cost-effective.
