In flight mechanics and aerodynamics, the lift coefficient (CL) as a function of angle of attack (α) represents the relationship between the lift generated by an airfoil or an aircraft’s wing and the angle at which the airfoil or wing is inclined to the oncoming airflow. CLα: The lift coefficient as a function of angle […]

In flight mechanics and aerodynamics, the drag coefficient (often denoted as Cd or Cdw) is a dimensionless number that quantifies the aerodynamic drag experienced by an aircraft or any other object moving through a fluid, such as air. It is a critical parameter used to describe the resistance an object encounters as it moves through

In flight mechanics, the change in the deflection angle of a control surface (Δδ) refers to the adjustment or movement of a specific control surface on an aircraft from its neutral or trimmed position. Control surfaces are movable aerodynamic surfaces on an aircraft’s wings, tail, or other parts that are used to control and maneuver

Perturbation velocities, often denoted as u^ and v^, are components of the velocity field in a fluid flow that represent small disturbances or variations from the mean or freestream flow velocity. These perturbations are typically much smaller than the main flow velocity and are used to analyze and describe deviations or fluctuations in the flow
