Total skin-friction drag (Df) refers to the aerodynamic drag that occurs due to the frictional resistance between a solid surface (such as an aircraft’s wing or body) and the air flowing over it. Skin-friction drag is a component of the overall drag force experienced by an object moving through a fluid medium, like air. When […]

The moment coefficient about the aerodynamic center (often denoted as “cm,ac”) is a fundamental parameter in aerodynamics and aircraft design. It quantifies the aerodynamic moment or torque exerted on an airfoil or wing due to changes in the angle of attack. In more technical terms, the moment coefficient about the aerodynamic center relates the pitching

The moment about the aerodynamic center (often denoted as M’,ac) is a measure of the aerodynamic torque or moment that is exerted on an airfoil or wing due to changes in the angle of attack. The aerodynamic center is a specific point on an airfoil or wing where the pitching moment remains relatively constant over

The location of the center of pressure (cp) for a cambered airfoil refers to the point along the chord where the combined effects of lift and drag are considered to act. It is the point where the total aerodynamic force can be balanced. The location of the center of pressure is a key parameter in

The location of the center of pressure is often denoted as “xcp,” and its position along the chord of the airfoil or wing is a key parameter in aircraft design and stability analysis. Calculating the exact location of the center of pressure (xcp) can be complex, especially for varying angles of attack and different airfoil

The moment coefficient about the quarter-chord (often denoted as “cm,c/4”) for a cambered airfoil refers to the aerodynamic moment or torque exerted around the airfoil’s quarter-chord point. This coefficient provides valuable information about the airfoil’s pitching behavior, stability, and balance. In the context of an airfoil, the quarter-chord point is located at 25% of the

The moment coefficient about the leading edge for a symmetric airfoil is often denoted as “cm,le.” This coefficient represents the aerodynamic moment or torque exerted around the airfoil’s leading edge. cm,le is typically calculated or measured about a specific point on the airfoil, often the quarter-chord point (25% of the chord length from the leading

In aerodynamics, “xac” typically refers to the location of the aerodynamic center of an airfoil or wing. The aerodynamic center is a point on the airfoil or wing where changes in lift and pitching moment (related to changes in angle of attack) occur without inducing changes in drag. It is an important concept in aerodynamic

The lift coefficient (cl​) is a dimensionless aerodynamic parameter that quantifies the lift-generating efficiency of an airfoil, wing, or other aerodynamic body in a fluid flow. It is a crucial parameter in aerodynamics and is used to describe the relationship between the lift force generated by the body and the various factors that influence lift
