The impact of airfoil thickness on airfoil stalling behavior and airfoil self-noise: an experimental investigation of two NACA series cambered airfoils

AIAA AVIATION 2023 Forum, 2023
This paper investigates the effect of airfoil thickness on the hydrodynamic near-field and radiated acoustic far-field of two cambered airfoils, namely the NACA 16-506 and NACA 16-616 profiles. Each airfoil has been experimentally investigated over a range of angles of attack encompassing the pre-stall, stall, and post-stall flow regimes, with static ...

Numerical Solution of the Generalized Airfoil Equation for an Airfoil with a Flap

SIAM Journal on Numerical Analysis, 1997
The authors consider the generalized airfoil equation which governs the pressure on an airfoil oscillating in a wind tunnel. In particular, an airfoil which contains a flap (or aileron) is examined, so that the profile function \(h\) has a simple jump in its first derivative at a point \(x_0\), \(-1 < x_0 < 1\). In this case the velocity function \(f\)

Aerodynamics and acoustics of transonic airfoil-airfoil interaction

3rd AIAA/CEAS Aeroacoustics Conference, 1997
As a two dimensional approximation to the outer region of a coaxial rotor, the How Gelds induced by transonic airfoil-airfoil interaction (AAI) are numerically simulated to investigate the aerodynamic and acoustic characteristics. A new approach is suggested to minimize the numerical compression wave generated when imposing initial condition for ...

Icing Research for Airfoil and Multi-Element Airfoil

24th AIAA Applied Aerodynamics Conference, 2006
*† ‡ Ice accretions over critical aerodynamics surface cause significant degradation in aircraft performance and handling qualities. In this paper, ice accretion on the leading edge of the NACA 0012 airfoil is predicted using CFD method. A four -order Runge -Kutta method is used to solve the droplet trajectory equation.
