Pressure difference on the surface is the difference in pressure between two points on a surface that forms the boundary between two fluid regions. The pressure difference can be caused by various factors, such as the curvature of the surface, the surface tension of the interface, the density and viscosity of the fluids, and the […]

Modified Newton’s sine-squared law is a formula that improves the accuracy of Newton’s sine-square law of air resistance for predicting the aerodynamic forces on a body moving in a fluid. The modified law accounts for the effects of the body shape and the flow separation by introducing a correction factor called the Newtonian pressure coefficient.

The Newtonian theory, often referred to as Newtonian physics or classical mechanics, is a fundamental framework in physics developed by Sir Isaac Newton in the late 17th century. It provides a comprehensive understanding of the behavior of objects in motion and is considered one of the cornerstones of physics. Pressure coefficient (Cp) Angle between a

The “mean chord” of an aircraft wing is a measure of the average width of the wing from the leading edge to the trailing edge. It is an important parameter in aircraft design and aerodynamics, particularly when calculating lift and drag characteristics. The formula for calculating the mean chord (ˉcˉ) of a wing depends on

Dynamic pressure, denoted as q, is a fundamental parameter in aerodynamics and aircraft design. It represents the kinetic energy per unit volume of a moving fluid (such as air) and is commonly used to describe the dynamic effects of air on an aircraft’s surfaces. Dynamic pressure is crucial in assessing aerodynamic forces and performance. The

The “landing distance” of an aircraft is the distance required for the aircraft to come to a complete stop after touching down on the runway. It includes both the ground roll distance (distance traveled on the runway) and the distance needed to decelerate and stop. Landing distance is a critical parameter for aircraft design and

“Incidence” in the context of aircraft design and aerodynamics refers to the angle at which a wing or other aerodynamic surface is set relative to the aircraft’s fuselage or reference axis. It’s a crucial parameter that affects the wing’s lift and drag characteristics, as well as the overall aerodynamic performance of the aircraft. The formula
