Lift Force: Lift is a force generated by the wings (or other lifting surfaces) of an aircraft as it moves through the air. It is created due to the pressure difference between the upper and lower surfaces of the wings. The Bernoulli principle and Newton’s third law of motion explain the generation of lift: Z=mg […]

Longitudinal Axis: The longitudinal axis, also known as the roll axis, is an imaginary line that runs from the nose to the tail of the aircraft, passing through its center of gravity. This axis is perpendicular to the wingspan and the lateral axis (roll axis) and parallel to the aircraft’s fuselage. Rotation about the longitudinal

The Pressure Coefficient over the lower surface, denoted as Cp,l, specifically refers to the pressure coefficient on the lower surface of the flat plate. The pressure coefficient (Cp) is a dimensionless parameter used in aerodynamics to describe how the local pressure at a specific point on the surface deviates from the freestream pressure. It quantifies

The Linearized Supersonic Pressure Coefficient, often denoted as Cp, is a term used in aerodynamics to describe the pressure distribution around an object moving at supersonic speeds. It provides a measure of how the local pressure at a specific point on the object’s surface deviates from the freestream pressure. Pressure coefficient (Cp) Angle (θ) in

The Prandtl-Glauert factor (λ) is a mathematical factor used in aerodynamics to account for compressibility effects when an object is moving at speeds close to the speed of sound (in the transonic regime). It is primarily used in subsonic and transonic aerodynamic calculations to approximate the effects of compressibility. Prandtl-Glauert factor (𝜆) Freestream Mach number

The lift slope for an infinite swept wing in compressible flow, denoted as a0,comp, is a key aerodynamic parameter that describes the rate of change of lift coefficient (CL) with respect to the angle of attack (α) for an infinitely long swept wing operating in compressible flow conditions. This parameter quantifies how the lift generated
