Device for simulating ground movement in aerodynamic wind tunnels

摘要

The aerodynamic wind tunnel intended for simulation tests of an object moving in proximity to the ground comprises a working section (1) having a wall (2) simulating the ground and in proximity to which there is disposed a test model (3). The wall (2) simulating the ground consists of a succession of independent cells (5) each including at least one suction orifice (6) and at least one blowing orifice (7) situated either downstream or upstream of the suction orifice (6) and supplied via at least one fan (8) with the gas sucked through the suction orifice 6).
