What is the difference between Aerodynamics and Flight Mechanics?
Aerodynamics is the study of how objects move through air and the forces that act upon them. It involves the principles of fluid mechanics, including the interaction between an object and the air around it.
Aerodynamics plays a crucial role in flight as it determines the lift, drag, and stability of an aircraft. The shape and design of an aircraft, as well as the airspeed and angle of attack, all affect its aerodynamic performance.
Lift is the force that keeps an aircraft in the air. It is created by the difference in air pressure above and below the wings of the aircraft. As air flows over the curved shape of the wings, it creates a higher pressure below the wing and a lower pressure above, resulting in an upward force.
Drag is the force that opposes the motion of an aircraft and is caused by the resistance of the air. It is affected by the shape and size of the aircraft, as well as its speed. On the other hand, thrust is the force that propels an aircraft forward, usually generated by the engines.
Pilots use their knowledge of aerodynamics to control and maneuver the aircraft. They adjust the angle of the aircraft's wings, the speed, and other factors to maintain lift, overcome drag, and achieve the desired direction and altitude of the flight.
