Mathematical simulation of a supersonic flow around complex objects. Influence of the position of a wing on the gasdynamic characteristics of a complex object

Abstract

Results of numerical simulation of a supersonic flow around spatial configurations of flying vehicles with the use of the Euler equations are presented. A model of a complex object was constructed on the basis of simpler base objects. Results of numerical solution of the problem on a three-dimensional flow around objects with an ogival-cylindrical airframe and a triangular wing with a diamond-shaped profile, arranged in different ways, at a Mach number M∞ = 4.03 and an angle of attack α = 10.1o have been analyzed. Calculation data were compared with the analogous data of a physical experiment.
