Cryogenic wind tunnels.

Les souffleries cryogéniques.

Author(s) : MIGNOSI A.

Summary

The aim of wind tunnel tests has always been for the model to reproduce flow conditions as close as possible to those of the actual plane and the model used in the test rig. Among the various parameters involved, and besides the Mach number, the Reynolds number plays an essential role. This parameter is generally too weak in wind tunnels because of the model's reduced size. It was possible to multiply it by a factor close to 5 by cooling the flow to a temperature of around 120 K. This cooling was made possible thanks to spraying liquid nitrogen spray into the unit's thermally insulated circuit.
