Aerodynamic force - Wikipedia
网页In fluid mechanics, an aerodynamic force is a force exerted on a body by the air (or other gas) in which the body is immersed, and is due to the relative motion between the body and the gas. Force. There are two causes of aerodynamic force: [1]: §4.10 [2][3]: 29. the normal force due to the pressure on the surface of the body.

网页2023年11月20日 · Aerodynamic Forces. Solids Interaction. When two solid objects interact in a mechanical process, forces are transmitted, or applied, at the point of contact. But when a solid object interacts with a fluid, things are more difficult to describe because the fluid can change its shape.
Aerodynamics - Wikipedia
网页In many aerodynamics problems, the forces of interest are the fundamental forces of flight: lift, drag, thrust, and weight. Of these, lift and drag are aerodynamic forces, i.e. forces due to air flow over a solid body.

What Is Aerodynamics? - Live Science
网页2014年9月20日 · Aerodynamics is the study of how gases interact with moving bodies. Because the gas that we encounter most is air, aerodynamics is primarily concerned with the...
Aerodynamics | Fluid Mechanics & Airflow Dynamics | Britannica
网页Aerodynamics, branch of physics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies passing through such a fluid. Aerodynamics seeks, in particular, to explain the principles governing the flight of aircraft, rockets, and missiles.
3.2.2: Generation of aerodynamic forces - Engineering LibreTexts
网页2024年6月26日 · Because of the lower pressure over the top surface of the airfoil is less than the pressure over the bottom surface, the airfoil experiences a lift force upwards. Therefore, this simplified statement of the equations of fluid mechanics give a qualitative idea of the aerodynamic forces.
Aerodynamics | How Things Fly - Smithsonian Institution
网页Aerodynamics is the study of forces and the resulting motion of objects through the air. Studying the motion of air around an object allows us to measure the forces of lift, which allows an aircraft to overcome gravity, and drag, which is the resistance an aircraft “feels” as it moves through the air.

网页2022年11月21日 · Aerodynamics is part of a branch of physics called fluid dynamics, which is all about studying liquids and gases that are moving. Although it can involve very complex math, the basic principles are relatively easy-to-understand; they include how fluids flow in different ways, what causes drag (fluid resistance), and how fluids conserve their ...
