Downwash modelling for three-lifting-surface aircraft configuration design [PDF]

Chinese Journal of Aeronautics, 2023
This paper introduces a semi-empirical model to predict the downwash gradient at the horizontal tail of a three-lifting-surface aircraft. The superposition principle applied to well established formulations valid for two lifting surfaces is not a ...

Lifting Surface in Subsonic Unsteady Regime

Meccanica, 1999
The paper deals with numerical solution of the integral equation for acceleration (pressure) potential in order to study subsonic linearized flows past harmonically oscillating wings in view of aeroelastic applications. The kernel of the integral equation is transformed such that the singularities (which are either integrable in elementary form or ...

Viscous Optimization of Interacting Lifting Surfaces

12th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2008
In this paper, the optimization of interacting lift ing surfaces based on design of experiments (DoE) and response surface technique (RSA) is investigated. Response surfaces of the considered problem are generated through the use of high-fidelity two-dimensional Reynolds Average Navier-Stokes simulations.

Exact Solutions for Lifting Surfaces

AIAA Journal, 1973
Abstract : The obstacle which prevented the determination of exact lifting surface solutions was the singularity at the wing tip. This problem has now been solved analytically for the circular wing and thereby, to an extent, for wings with parabolic wing tips in general. The paper reports the analytical results. It describes how numerical solutions for
