Ground Viscous Effect on 3D Flow Structure of a Compound Wing-in-Ground Effect

Ground Viscous Effect on 2d Flow of Wing in Ground Proximity

Viscous effect of wing in ground effect in wind tunnel test was investigated numerically. Ground settings in wind tunnel test were simulated by specifying different ground boundary conditions in CFD. It was revealed for fixed-ground based wind tunnel test that: boundary layer developed from the ground deforms effective ground surface and introduces a decreased effective ground clearance; a shar...

Aerodynamics of Gurney Flaps on a Wing in Ground Effect

Wing in Ground Effect Craft Review

It has long been recognised that flight close to a boundary surface is more aerodynamically efficient than flight in the freestream. This has led to the design and construction of craft specifically intended to operate close to the ground and fly 'in ground effect'. A great range of Wing in Ground effect craft (WIGs) have been manufactured ranging from 2 seat recreational vehicles to 500 tonne ...

A Practical Method for Investigation of Aerodynamic and Longitudinal Static Stability of Wing-in-Ground Effect

The purpose of this paper is to present a fast, economical and practical method for mathematical modeling of aerodynamic characteristics of rectangular wing-in-ground effect (WIG). Reynolds averaged Navier-Stokes (RANS) equations were converted to Bernoulli equation by reasonable assumptions. Also Helmbold's equation was developed for calculation of the slope of wing lift coefficient in ground ...
