aerodynamic drag \aer`o*dy*nam"ic drag\, n. 1. the resistance caused by a gas to the motion of a solid body moving through it. Studied in aerodynamics.
Wikipedia
In aerodynamics, aerodynamic drag is the fluid drag force that acts on any moving solid body in the direction of the fluid freestream flow. From the body's perspective (near-field approach), the drag comes from forces due to pressure distributions over the body surface, symbolized D, and forces due to skin friction, which is a result of viscosity, denoted D. Alternatively, calculated from the flowfield perspective (far-field approach), the drag force comes from three natural phenomena: shock waves, vortex sheet, and viscosity.
Usage examples of "aerodynamic drag".
The size of an artillery shell was limited by the diameter of the gun barrel, and the size of a bomb was limited by the aerodynamic drag it imposed on the aircraft that carried it.
But in his mind he felt the bucking control column in his hands as the ship buffeted through maximum aerodynamic drag.
Numbers were important because whatever fears we might have had concerning the shattering of our minds were largely dispelled by the satisfaction of knowing precisely how we were being driven mad, at what decibel rating, what mach-ratio, what force of aerodynamic drag.
Its oversized fins provided enough aerodynamic drag to keep it pointed in the proper direction as gravity began to reclaim the object for its own.
Three-point shooters, whether they know it or not, compensate for aerodynamic drag.
The ungainly structural addition would create a negative aerodynamic drag inside a planet's atmosphere, but in the vacuum of space there was little effect on the craft's speed.
