The performance of three different ramjet engine inlets is numerically considered in this study. The geometries used are planar with the free stream Mach = 2.5. Inlet 1 is chosen from literature, a single oblique shock followed by a normal one, which given a low value of total pressure recovery. Inlets 2 and 3 are designed in a way to produce a series of oblique shocks merging at the cowl lip of the engine followed by a normal hock. The compression process in inlet 2 is completely performed in external part of the inlet. Instead inlet 3 is given a mixed internal and external compression. Inviscid Roe scheme with 3rd order accurate in space and second order accurate in time and second order predictor–corrector MacCormack scheme are applied in this study and also commercial FLUENT software package. The results are in good agreement with literature.<\div>

In this paper we propose a novel Fuzzy Logic Control Architecture (FLCA) for regulation of systems as well as unknown nonlinear model
uncertainties. The proposed Fuzzy Logic Control Architecture (FLCA) aims to handle time varying and unknown delays that occur.
Results indicate that acceptable responses can be achieved even in presence of large uncertainties and time delays.<\div>
