The lift slope (a) of the elliptical wing is related to the lift slope (a0) of the individual airfoil section from which the wing is constructed and the aspect ratio (AR) of the wing. The lift slope (a) for the entire wing is derived from the lift slope (a0) of the airfoil section but takes […]

In flight mechanics, the term “velocity at the beginning of the flight” usually refers to the initial velocity of an aircraft or any flying object at the moment it starts its flight or takes off from the ground. This velocity is crucial in understanding the dynamics and performance of the aircraft during the early stages

Induced drag coefficient (CDi) is a dimensionless aerodynamic parameter that quantifies the portion of drag generated by the production of lift on a wing or an airfoil. When an aircraft generates lift to stay airborne, it also creates a certain amount of drag as a consequence. This type of drag is known as induced drag.

In flight mechanics, the term “corresponding lift at power required” refers to the amount of lift generated by an aircraft’s wings at a specific power setting. It is an essential concept used to analyze and understand an aircraft’s performance, especially during different phases of flight like climb, cruise, and descent. Cl at power required (Clmp)

The coefficient of lift (CL) for a symmetric airfoil is a dimensionless parameter used in aerodynamics to quantify the lift generated by the airfoil when it is placed in a flow of air. For a symmetric airfoil, the upper and lower surfaces have the same shape, resulting in zero camber (i.e., the mean camber line

Stagnation points refer to specific locations in the flow field where the velocity of the fluid becomes zero, resulting in stagnation or zero velocity. For the flow over a cylinder, there are two primary types of stagnation points: the forward stagnation point and the rear stagnation point. R is the radial coordinate of the stagnation

The radial velocity for a three-dimensional point source represents the velocity of the fluid flow at any given distance (r) from the point source. The point source is a theoretical concept used in potential flow theory to model fluid flow emanating from a single point or converging towards it. The radial velocity describes how the
