Sample text

For a given shape and size of the object, its orientation relative to the freestream, and for a specified set of atmospheric properties, the aerodynamic forces and moments are directly proportional to the square of the flight speed. The reference length and area indicating an object’s size determine the magnitude of the aerodynamic forces and moments experienced by it. The reference area is usually selected to be the wing’s planform area defined as the area of the wing as seen from the top. The reference length is usually a characteristic dimension of the object along the expected flow direction.

2 Streamlined Shapes Since air is a gas with a low viscosity, the magnitude of shear stresses on the wing of an airplane is typically much smaller than the exchange of momentum normal to the flow (pressure), because of its high Reynolds number. Therefore, the shape of an airplane wing can be designed to produce the maximum possible lift due to the pressure variations over it. However, even a small viscous shear stress results in a drag that must be balanced by the thrust of the engines, and determines the fuel consumption (hence flight efficiency).

Therefore, a flight with a varying airspeed is generally not level, and the airplane tends to bounce up and down. A student pilot just beginning to learn flying, experiences such a situation, because the angle-of-attack is kept varying by the arbitrary application of the control inputs. Because the natural equilibrium for level flight requires maintaining a constant flight speed at any given time, the thrust provided by the engines must exactly balance the drag of the airplane.
