Drag reducer for lift surface of aircraft

摘要

One or more aerodynamic bodies of preselected shape and placement are employed on the lower surface of an aircraft wing or other aerodynamic lifting surface for the purpose of reducing its drag. These anti-drag bodies singly or collectively provide a reduction in the lower speed profile drag of the associated lifting surface, an increase in its lift at a given angle of attack, and an increase in its critical Mach number.
