Induced velocity at a specific point P refers to the change in velocity that is caused by the presence of some external influence, such as a moving object or a flow pattern, at that particular point. In fluid dynamics, induced velocity is commonly associated with the influence of vortices, sources, or other flow elements on […]

The stream function (Ψ) is a mathematical concept used in fluid dynamics to describe the flow patterns of a two-dimensional, incompressible fluid. It helps visualize and analyze fluid motion by representing the streamlines, which are curves that are always tangent to the velocity vector of the fluid at a given point. Strength of the Doublet

The yawing moment is the tendency of an aircraft to rotate around its vertical axis (yaw). This motion is typically caused by asymmetrical aerodynamic forces acting on the aircraft, such as those created by the vertical tail fin. CnrW: Yawing moment damping coefficient contributed by the wing. This component represents the aerodynamic forces and moments

The yawing moment coefficient (Cnp​) is a measure of the aircraft’s response to sideslip (sideways airflow) and yawing motion. It indicates how the aircraft tends to rotate about its vertical axis (yaw axis) in response to yawing forces. The equation Cnp​=CnpW​+CnpV​ represents the relationship between the yawing moment coefficient (Cnp​) of an aircraft and
