What is flat plate?

A flat plate is geometrically the simplest airfoil one can think of. In spite of its simplicity, its aerodynamic behavior can give significant values and im- plications to design and validation of computational or experimental models.

How to Calculate Equivalent Parasite Drag Area?

Equivalent Parasite Drag Area calculator uses Flat Plate Area = Form Factor Drag*Skin Friction Coefficient*Aircraft Wetted Area to calculate the Flat Plate Area, Equivalent Parasite Drag Area is a concept used in aerodynamics to represent the total drag of an aircraft due to non-lifting components such as the fuselage, wings, tail surfaces, and any other protruding features. It's called "equivalent" because it's a hypothetical area that, if exposed to the airstream, would produce the same amount of drag as the entire aircraft. Flat Plate Area is denoted by A symbol.

How to calculate Equivalent Parasite Drag Area using this online calculator? To use this online calculator for Equivalent Parasite Drag Area, enter Form Factor Drag (Φ_f), Skin Friction Coefficient (μ_f) & Aircraft Wetted Area (S_wet) and hit the calculate button. Here is how the Equivalent Parasite Drag Area calculation can be explained with given input values -> 10.9728 = 1.499*0.72*10.16.
