Abstract
Statistical data are presented on the number and frontal areas for principal types of manufacturing and constructive imperfections characterizing the condition of aircraft external surface and the level of parasitic drag. Basic laws of varying drag coefficients for various types of surface excrescences as functions of Mach and Reynolds numbers are analyzed. The methodology is considered for evaluating requirements for aircraft surface finish based on the specified level of parasitic drag.
