The Characteristics of Some Slender Cambered Gothic Wings at Mach Numbers from 04 to 2.0

摘要

Wind-tunnel tests have been made on a series of cambered slender wings of modified gothic planform. The main purpose of these tests was to investigate camber designs which have low lift-dependent drag and a given centre-of-pressure position ahead of the aerodynamic centre.nThe results show that at the design conditions the centre-of-pressure position is close to or slightly ahead of, the design position and the trimming power associated with the forward position of centre of pressure is largely maintained throughout the speed range. The maximum lift/drag ratios of the cambered wings are slightly greater than those of the uncambered wing.
