![]() Explaining Airfoil Lift With Bernoulli’s Equation and the Coanda EffectĪircraft wings, otherwise called airfoils, are significant in creating the majority of the lifting force. We will focus on airfoil lift in the upcoming section. Lift keeps the airplane flying through the air. The force that holds the airplane in the air is called the lifting force, or simply lift. It is this weight that brings the aircraft in motion back to land. Aircraft are made of metals, and the weight of them exert a force downward due to gravity. The drag force is exerted in the opposite direction of motion. Thrust is the force that moves the aircraft in the direction of motion.ĭrag is the force that slows down the airplane motion, and is caused by air friction and differences in air pressure. The aircraft propeller is the primary creator of thrust in airplanes. In airplanes, the propeller produces propulsive force by pulling air in and pushing it out in the opposite direction, thereby creating a forward motion. There are four key forces that enable aircraft flight: thrust, weight, lift, and drag. Let’s examine how an airfoil creates lift and what the factors affecting airfoil lift are. The streamlined structure of an airfoil is significant in creating this lift. The airfoil lift is produced by turning the airflow the interaction between the incoming airflow and the airfoil results in aerodynamic lift. Have you ever wondered how it is possible for airplanes made of such heavy metals to stay in the air? Airplanes are able to fly due to the lift created by airfoils. The force that holds an airplane in the air is called the lifting force.Īircraft wings, otherwise called airfoils, are significant in creating the majority of the lifting force.Īirfoil lift depends on various factors such as the geometry of the airfoil and the inclination of the airfoil to the airflow as well as airflow velocity, density, viscosity, and compressibility.
