Low speed wind tunnel with adjustable moving boundary

A low speed wind tunnel having at least one moving boundary, comprising:

• a fan driven to produce an air flow;
• a wind tunnel test section having an air inlet in fluid communication with the air flow from the fan, the wind tunnel test section being constructed by a plurality of walls defining a space through which the air flow passes in a longitudinal direction from the air inlet, at least one of the plurality of walls being an adaptive continuously dispaceable movable boundary wall;
• a support structure for supporting the at least one adaptive continuously displaceable movable boundary wall in a contour compensating for a shape of an object under test positioned in the space within the wind tunnel test section;
• and
• at least one driving device coupled to the at least one adaptive continuously displaceable movable boundary wall for driving the boundary wall to move in a direction corresponding to a streamline passing around a test object and a speed of the air flow passing through the space of the wind tunnel test section.
