Unsteady numerical estimation of the aerodynamic loads of the Krueger flap
Journal Title: INCAS BULLETIN - Year 2012, Vol 4, Issue 1
Abstract
The aim of this paper is to study the unsteady aerodynamic interaction between a Krueger flap and a three-element airfoil using the finite volume method to solve the Unsteady Reynolds-Averaged Navier-Stokes equations. For a better understanding of this unsteady interaction, the Krueger flap is placed at different positions. Our results clearly show that the airfoil’s aerodynamic performance and the pressure distributions are strongly influenced by the Krueger flap position.

Optimization of the flueric actuators testing system
A supplying system for air with precisely controlled temperature, pressure, flow and speed has been designed in order to test the flueric actuator. All these parameters are monitored and the acquired data are stored on a...
Speech control interface for Eurocontrol’s LINK2000+ system
This paper continues recent research of the authors, considering the use of speech recognition in air traffic control. It proposes the use of a voice control interface for Eurocontrol’s LINK2000+ system, offering an alte...
Numerical Investigations of Dynamic Stall Control
In this paper we investigated numerically the dynamic stall phenomenon and the possibilities to control it, with application to vertical axis wind turbines (for urban users). The Phenomenon appear at low tip speed ratio...
Discrete Adjoint-Based Simultaneous Analysis and Design Approach for Conceptual Aerodynamic Optimization
In this paper, a simultaneous analysis and design method is derived and applied for a non-linear constrained aerodynamic optimization problem. The method is based on the approach of defining a Lagrange functional based o...
Wave-wave regular interactions of a gasdynamic type
Two gas dynamic analytic approaches [of a Burnat type / Martin type] are respectively used in order to construct two analogous and significant pairs of classes of solutions [isentropic pair / anisentropic (of a particula...
