EAGES 11 - Easy Ways to Study Ground Effects - Jan Monchaux and Stéphan Aubin

ABSTRACT

This paper discusses all the simple methods developed in SUPAERO to study the different aerodynamic ground effects and understand their main characteristics. It gives a student point of view of this complex phenomena, and illustrates some possibilities of easy studies of both the Venturi and the ”lifting” ground effects. It is clearly focusing on experimental approaches, and the results must be considered for their tutorial aspect. After a short presentation of the different constraints due to the presence of the ground and the ways used in the case of the paper to solve it, the case of the Mercedes CLK-GTR and its study will be presented, followed by a more classical study of the WIG  phenomenon in wind tunnel.
