A numerical technique for analysis of wave drag at lifting conditions

A numerical technique f o r an application of t h e f a r -f i e l d l i n e a r theory i s presented.This technique, when adapted t o t h e high-speed electronic dig i t a l computer, provides a p r a c t i c a l means for analyzing t h e t o t a l wave drag of an airplane a t l i f t i n g conditions.An indication of t h e accuracy of t h e method a t l i f t i n g conditions i s shown by comparing measured pressure signa t u r e s a t various azimuth angles about an airplane model with those predicted by theory.Calculations a r e made t o i l l u s t r a t e some e f f e c t s of configura t i o n variables on t h e t o t a l wave drag of an airplane a t l i f t i n g conditions.
