At left is a generic chart comparing airspeed to drag, including induced drag--that results from producing lift--and parasite drag, which results from hanging things like landing gear and radio antennas out in the breeze.
The total drag of an object moving through the air, can be achieved by summing up induced drag and parasite drag. Both lift and drag are functions of a number of variables such as the density of the air, the velocity of the object through the air and the geometry of the object.
They're lightweight, induce no parasite drag on the engine and flow massive amounts of cool air through the radiator core.
Parasite drag remains the same, but there's an overall drag reduction as the amount of lift generated remains the same.
To do so, we need to streamline the elevator/stabilator as depicted on the previous page, minimizing both the induced drag (a byproduct of the lift being generated) and parasite drag (created when the elevator/stabilator is deflected) and maximizing speed.
