Fast aerodynamics prediction of laminar airfoils based on deep attention network
The Physics of Fluids, 2023The traditional method for obtaining the aerodynamic parameters of airfoils by solving Navier-Stokes (NS) equations is a time-consuming computing task.In this article, a novel data-driven deep attention network (DAN) is proposed for the reconstruction of

Experimental Study of Aerodynamics and Wingtip Vortex of a Rectangular Wing in Flat Ground Effect
Journal of Fluids Engineering, 2019The ground effect on the aerodynamics and tip vortex flow of a rectangular wing is investigated experimentally at Re = 2.71 × 105. The results show that there is a large lift increase with reducing ground distance. By contrast, only a small drag increase

Experimental investigation of ionospheric aerodynamics effects
AIP Conference Proceedings, 2019The accurate prediction of the motion of resident space objects (RSOs) in Low Earth Orbit (LEO) requires knowledge of all forces acting on these objects, which includes active and inactive (e.g. debris) objects. In this context, charged particle interactions with RSOs and associated orbital perturbations resulting from charged aerodynamic effects, i.e.

Experimental Investigation of Annular Wing Aerodynamics
Journal of Aircraft, 2009A low-speed wind-tunnel investigation was conducted to explore the behavior of annular (ring) wings. Effects of aspect ratio as well as gap were investigated. Ring wings using a low Reynolds number Eppler section and a NACA 0012 profile were manufactured and tested. Measurements were recorded using a six-component sting balance.

Aerodynamic Development of an Experimental car
SAE Technical Paper Series, 1989<div class="htmlview paragraph">An experimental research car that runs at over 300 km/h has been developed by aerodynamic improvement. To achieve this target with 295PS, 2000cc engine, a coefficient of drag CD = 0.20 was required. The results of basic research and some fundamental aerodynamics are described.

Simulation of javelin flight using experimental aerodynamic data
Journal of Biomechanics, 1984This paper discusses computer simulation of the differential equations which describe javelin dynamics in flight. It is shown that the use of experimental aerodynamic forces and moments in the equations is preferable to theoretical approximations for these forces and moments which have been used in previous studies.
