The induced angle of attack (αi) is an aerodynamic term used to describe the effective angle of attack experienced by a wing or lifting body due to the presence of downwash from its own circulation. When an airfoil or wing generates lift, it creates a circulation around its surface, which leads to a downward deflection […]

The downwash (w) is the vertical component of the velocity resulting from the generation of lift by the lifting body. As the airfoil or wing generates lift, it induces a circulation (Γ) around its surface. This circulation is related to the lift and the circulation distribution along the wing span. The downwash velocity decreases with

In aerodynamics, an elliptical lift distribution refers to a specific type of lift distribution along the span of an airfoil or wing. It is an ideal lift distribution that results in minimum induced drag for a given amount of lift. An elliptical lift distribution is known for its aerodynamic efficiency since it minimizes induced drag,

Overall lift refers to the total upward force generated on an object, such as an airfoil or wing, when it is subjected to a fluid flow (e.g., air). The overall lift force is a result of the pressure distribution and the circulation around the object due to its interaction with the fluid flow. When air

This circulation distribution is often encountered in aerodynamics and potential flow theory, particularly when analyzing airfoils or wings with a certain circulation distribution along their span. The expression indicates that the circulation is zero at the edges (when 2y=±b/2) and reaches its maximum value Γ0 at the centerline (when y=0). The shape of the circulation

The “Coefficient of Lift” (CL) is a dimensionless parameter that represents the lift force generated by an airfoil or wing relative to the dynamic pressure of the airflow. The coefficient of lift is defined as the ratio of the lift force (L) acting on the airfoil or wing to the dynamic pressure (q) and the

A doublet flow is a potential flow solution that represents the flow field around a doublet. A doublet is a combination of a source and a sink located at the same point with equal strengths but opposite signs. The doublet flow has interesting flow characteristics. It creates a flow pattern where fluid flows radially towards

Average fuel per hour” refers to the rate at which an aircraft consumes fuel over a given time period of one hour. It is typically expressed in terms of fuel flow rate, measured in pounds per hour (lb/hr), gallons per hour (gal/hr), liters per hour (L/hr), or other relevant units of mass or volume per

The stream function (ψ) is a mathematical function used to describe the flow of an incompressible fluid in two-dimensional flow scenarios. For a combined flow, the stream function represents the superposition of two or more individual flows. The combined flow can be achieved by adding or subtracting the stream functions of the individual flows. The

In flight mechanics, the “drag coefficient” (CD) in turning flight refers to the dimensionless parameter that quantifies the drag force acting on an aircraft during a turn. It is a crucial factor in understanding the aerodynamic performance of the aircraft while maneuvering. Ta / (0.5 * ρ * V^2 * S) Ta: Thrust force acting
