The pressure coefficient for the flat plate bottom surface (Cp3) is a dimensionless quantity that measures the relative change in pressure on the lower surface of the plate due to the oblique shock wave that forms when the plate is at a small angle of attack to the supersonic or hypersonic flow.  Pressure coefficient for […]

The pressure coefficient for the flat plate upper surface under the expansion wave (Cp2) is a dimensionless quantity that measures the relative change in pressure on the upper surface of the plate due to the expansion wave that forms when the plate is at a small angle of attack to the supersonic or hypersonic flow.  

Wave drag coefficient for a hypersonic flat plate is a dimensionless quantity that measures the ratio of the wave drag force to the dynamic pressure times the reference area of the plate. Wave drag is the drag due to shock waves that form on the surface of the plate when it moves at speeds higher

The total drag coefficient is the sum of the wave-drag coefficient cd,w and the friction-drag coefficient cd,0. This is a statement that describes the total drag or resistance of a body moving at supersonic or hypersonic speeds in a fluid environment, such as air or water. The wave-drag coefficient cd,w is the drag due to

The total drag coefficient for a flat plate is a dimensionless quantity that measures the total drag or resistance of a flat plate in a fluid environment, such as air or water. It is composed of Zero lift drag coefficient (cd,0). Total drag coefficient (cd) Zero lift drag coefficient (cd,0)

The maximum coefficient of lift to drag ratio is a measure of the maximum aerodynamic efficiency of an airfoil or an aircraft. It is the ratio of the lift force to the drag force when they are both at their maximum values for a given flight condition. The higher the maximum coefficient of lift to

The maximum lift-to-drag ratio depends only on the drag coefficient at zero lift, which is a measure of the parasitic drag or skin friction of the airfoil. The lower the drag coefficient at zero lift, the higher the maximum lift-to-drag ratio. The maximum coefficient of lift to drag ratio is a measure of the maximum aerodynamic

The maximum coefficient of lift to drag ratio is a measure of the maximum aerodynamic efficiency of an airfoil or an aircraft. It is the ratio of the lift force to the drag force when they are both at their maximum values for a given flight condition. The higher the maximum coefficient of lift to

The angle of attack for a flat plate is the angle between a reference line on the plate (often the chord line) and the vector representing the relative motion between the plate and the fluid through which it is moving. The angle of attack determines how much the plate deflects or bends the fluid flow

The coefficient of lift-to-drag ratio, often denoted as cl/cd​, is a dimensionless parameter used in aerodynamics to assess the efficiency of an airfoil, wing, or aircraft. It represents the ratio of the coefficient of lift (cl) to the coefficient of drag (cd​) and provides insights into how effectively an aircraft generates lift relative to the
