The lift coefficient (Cl) for an airfoil section located at an arbitrary spanwise station represents the dimensionless measure of the lift generated by that specific section of the airfoil.  Local section lift slope (a0) in per rad Effective angle of attack at the spanwise station y₀ (αeff(y₀)) in rad Zero-lift angle of attack (αL=0) in […]

The induced angle of attack at an arbitrary spanwise station refers to the angle of attack that is created at a specific location along the span of an aircraft’s wing due to the presence of downwash from neighboring sections of the wing. In other words, it represents the effective angle of attack experienced by a

In other words, it represents the effective angle of attack experienced by a

The downwash distribution along the y-axis for a single horseshoe vortex can be described using potential flow theory. A horseshoe vortex is often used as a simplified model to represent the vortical flow structure generated by the wingtip or wingtip vortex system. In this case, we’ll consider a horseshoe vortex where the vortex elements are

Cartesian coordinate systems, the y-coordinate (y2) for the doublet refers to the vertical position of the doublet source (or sink) along the y-axis. The y-axis is one of the two perpendicular axes in a Cartesian coordinate system, typically representing the vertical direction. For a doublet located in a Cartesian coordinate system with its center at

Cartesian coordinate systems, the y-coordinate (y1) for the doublet refers to the vertical position of the doublet source (or sink) along the y-axis. The y-axis is one of the two perpendicular axes in a Cartesian coordinate system, typically representing the vertical direction. For a doublet located in a Cartesian coordinate system with its center at

Cartesian coordinate systems, the y-coordinate (y1) for the doublet refers to the vertical position of the doublet source (or sink) along the y-axis. The y-axis is one of the two perpendicular axes in a Cartesian coordinate system, typically representing the vertical direction.  Cartesian coordinate for y axis for doublet one (y1)  r1 is the radial

The radial distance of a doublet refers to the perpendicular distance from the doublet source (or sink) to a specific point in the flow field. The doublet is a theoretical construct used to model certain flow patterns, and its radial distance is an important parameter when analyzing its influence on the surrounding fluid.   r2 is

The radial distance of a doublet refers to the perpendicular distance from the doublet source (or sink) to a specific point in the flow field. The doublet is a theoretical construct used to model certain flow patterns, and its radial distance is an important parameter when analyzing its influence on the surrounding fluid.  r1 is

The polar angle (θ2) for a doublet is the angle measured in radians from a reference axis (usually the positive x-axis) to a point in the flow field that is affected by the doublet.  sin 𝜃2 is the polar angle for doublet two. (x2, y2) are the Cartesian coordinates of the point the position of
