Preamble Interaction of shock waves with turbulent boundary layers is important in many aerospace applications. Examples in external aerodynamics include control surfaces, wing body junctions, and multi-body aerodynamics. In high-speed propulsion systems, shock-boundary layer interaction (SBLI) can occur in intakes, supersonic combustion chambers and nozzles. Computational fluid dynamics (CFD) ...

The paper presents computational prediction of aerodynamic hysteresis loops in static conditions for a two-dimensional aerofoil that was used as cross-section profile rectangular wing with an aspect ratio five, tested the TsAGI T-106 wind tunnel at Reynolds number and Mach . Tests showed minor changes curvature leading edge thin lead to significant increase maximum lift coefficient when appear ...

The objective of this study is to compare and contrast three numerical algorithms that can be used to estimate the forces and pressure distribution on wings in flapping motion. All algorithms are used to solve the unsteady Navier-Stokes equations in two dimensions at low Reynolds Numbers. The four algorithms are a) an A-stable, implicit discretization b) the time-spectral algorithm that implici...

A numerical method based on Reynolds Averaged Navier–Stokes (RANS) equations and a high-efficiency trim model is developed to simulate the aerodynamics of coaxial rotor. Farassat 1A are used for prediction thickness loading noise. Hover cases different thrust coefficients with torque balance conducted. The sound pressure history observation points positioned below rotor disk plane analyzed. Res...

The present paper introduces the sloshing effects on aeroelastic stability and response of flying wing configurations. Using reduced order model based data provided by computational fluid dynamics data, description slosh is introduced into an integrated modelling that accounts for both rigid elastic behaviour flexible aircraft. fully unsteady aerodynamics, modelled in frequency domain via doubl...
