DESIGN OF THE ENGINE INTAKE DUCT WITH STEALTH TECHNOLOGY REQUIREMENTS
With the use of state-of-the art computational electrodynamics methods various technical solutions are esti- mated that provide the duct inlet low level radar signature. A comparison of the calculated and experimental characteristics of low observable intake duct is made. On the basis of the numerical solutions of the Navier - Stokes equations the aerody- namic characteristics of the S-shaped intake duct are evaluated. It is shown that the design of the intake duct of low observ- able shape is necessary to match with the rational compromise between stealth and aerodynamics requirements.
