MATHEMATICAL SIMULATION OF A SUPERSONIC FLOW AROUND COMPLEX OBJECTS. INFLUENCE OF THE POSITION OF A WING ON THE GASDYNAMIC CHARACTERISTICS OF A COMPLEX OBJECT
V. F. Volkov UDC 518.4:533.4:629.7 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 = 10.1o have been analyzed. Calculation data were compared with the analogous data of a physical experiment.
