Boundary Layer Ingestion (BLI) is a promising propulsion integration technology capable of enhancing aircraft propulsive efficiency. The Propulsive Fuselage Concept (PFC), tube-and-wing configuration with an aft-fuselage-mounted BLI propulsor, particularly suited for BLI. Although extensively studied on system level, the aerodynamic performance PFC, resulting from complex interaction between ai...

The search for the temperature disturbance causing transition between regular and Mach reflections in a dual solution domain is addressed in an optimization statement. The gradient of the discrepancy between the current and target flow fields was calculated using the adjoint equations. The control was determined by a gradient based optimization. The flowfield simulation is verified via a poster...

Abstract. Three-dimensional transonic flow over a delta wing is investigated using several turbulence models. The performance of linear eddy viscosity models and an explicit algebraic stress model is assessed at the start of vortex flow, and the results compared with experimental data. To assess the effect of transition location, computations that either fix transition aft of the leading edge o...

Steady, inviscid, irrotational flow of a perfect gas in two dimensions is considered in the tangent gas approximation. A fast and accurate method of solution is proposed and solved numerically. Comparison of tangent gas and exact flows are presented. Tangent gas solutions when used as the first step in the iterative solution of the exact flowfield are shown to give substantial reduction in comp...
