Transient wing in ground effect aerodynamics: comparisons of static and dynamic testing

Transient wing in ground effect aerodynamics: comparisons of static and dynamic testing
Transient wing in ground effect aerodynamics: comparisons of static and dynamic testing
The aerodynamic investigation of vehicles in wind tunnels has historically been performed via a series of time averaged measurements at fixed static attitude. However, due to their nature vehicles exploiting ground effect tend to be inherently dynamic and thus there is potential for improvement in the accuracy and predictive capability of wind tunnel testing. This paper describes a novel approach to testing that allows for an increase in fidelity by performing dynamic tests in the wind tunnel. This improved capability is then used to evaluate the transient aerodynamic behaviour of ac wing in ground effect.

Results from wind tunnel tests of a single element GA(W)-1 wing in ground effect undergoing a heaving motion are compared to force values with the wing stationary at a number of positions.

Abstract

The aerodynamic investigation of vehicles in wind tunnels has historically been performed via a series of time averaged measurements at fixed static attitude. However, due to their nature vehicles exploiting ground effect tend to be inherently dynamic and thus there is potential for improvement in the accuracy and predictive capability of wind tunnel testing. This paper describes a novel approach to testing that allows for an increase in fidelity by performing dynamic tests in the wind tunnel. This improved capability is then used to evaluate the transient aerodynamic behaviour of ac wing in ground effect.

Results from wind tunnel tests of a single element GA(W)-1 wing in ground effect undergoing a heaving motion are compared to force values with the wing stationary at a number of positions.
