FIELD: physics.
SUBSTANCE: invention relates to the field of aerodynamics and pilot may be used for obtaining of Hypersonic gas flow in the laboratory. Wind tunnel comprises symmetrically mounted to form a total prechamber two differential pressure booster pistons which are stepped and are movable towards each other. To the body of the second multiplier-axis is attached a small pressure booster comprising a two-stage piston, a small stage which is in contact with a large stage piston second multiplier, and the small space over-the-piston multiplier connected via a high-speed air valve to the receiver.
EFFECT: technical result is to increase the experimental capabilities of the wind tunnel a short duration.
