The circular ring drag body is investigated in the measuring section of the wind tunnel HM 170. The drag body consists of a circular ring made of steel sheet and a mounting rod made of corrosion-resistant steel. The circular ring is painted black. The drag body is placed in the force sensor, this indicates the drag force as a measured value in flow around bodies.
