The transition from laminar to turbulent boundary layer has been largely investigated in the literature on the experimental side as well as on the numerical side but the processes specifically involved in both transitional and unsteady flows (unsteady aerodynamic or aeroelasticity) have to be studied more in details. This paper describes an experim...
In this paper, a methodology is presented to size an aircraft wing-box accounting for steady and dynamic loads combined with active control. Several aerodynamic corrections are used and benchmarked to ensure a consistent level of fidelity during the load analysis. Reduced order models (ROM) of the aircraft movables, gust loads and maneuvers loads a...
peer reviewed / A new unsteady aerodynamic modeling methodology for calculating transonic flutter characteristics is presented. The main idea of the methodology is to obtain the unsteady flow response to small amplitude periodic deformations of a structure over a large range of oscillation frequencies through the interpolation of the most dominant ...
Due to the increase in computer performance coupled CFD-CSM (Computational Fluid Dynamics - Computational Structural Mechanics) tools are state of the art for aeroelastic simulation of aircraft. Such a coupled CFD-CSM tool allows very accurate computations of aeroelastic phenomena. However, due to its complexity and computational expense, it is not...
The need to reduce the pollutant impact of aircraft emission drives the research on aircraft design progress through off-design performance improvement. This report proposes to investigate the effect of maneuver load alleviation technology via wing control surfaces. A methodology is presented to model the MLA technology in aircraft conceptual desig...
A numerical aeroelastic assessment of a highly loaded high pressure compressor exposed to flow disturbances is presented in this paper. The disturbances originate from novel, inherently unsteady, pressure gain combustion processes, such as pulse detonation, shockless explosion, wave rotor or piston topping composite cycles. All these arrangements p...
[ES] El método de los paneles en 2D (vortex lattice method) se usa en arodinámica para predecir la distribución de la sustentación en superficies de alas. Su implementación y fundamentos son sencillos cuando se ha visto un curso de aerodinámica básica. El objetivo del presente Trabajo Final es extender e implementar el método para aerodinámica no-e...
The proposed approach in this paper aims to bring the accuracy of CFD to quick linear aeroelastic simulations for structural sizing. This is achieved by deriving reduced-order models (ROM) of the aircraft movables, gust loads and manoeuvres loads from rigid CFD analysis and to use these as substitutes for the loads in the aeroelastic simulation. Th...
