Complex approach to aerodynamic design of inlet ducts with submerged vortex-free air intakes

Abstract

The paper shows the possibility of improving gas-dynamic characteristics of a submerged air intake and presents a technology of developing design solutions according to the principle of conformity to the flow lines. The gas-dynamic principle of shaping is provided by means of computer-aided integrated technologies of design and application of numerical visualization methods as design tools. The revealed regularity of the working process of the external streamline of the preceding airframe surfaces unambiguously defines the fundamental design distinctions of the conformal air intake in the form of the converging side edges on the stream and determines its advantages over the analogs.
