WIND TUNNEL TESTING APPARATUS FOR SIMULTANEOUS MEASUREMENT OF DRAG FORCE AND LIFT FORCE

摘要

The present invention relates to a wind tunnel testing apparatus that is capable of effectively analyzing lift, drag, and a lift-drag ratio (lift/drag) by simultaneously measuring the lift and the drag produced by shapes, angles of attack, wind speeds, and Reynolds number of various objects. The present invention realizes a wind tunnel structure that is capable of ensuring a uniform flow rate by rectifying a fluid and a novel wind tunnel testing apparatus that uses a link combination between a lift load cell and a drag load cell, a computer for digitization of measured values, and the like, and thus the lift and drag produced in the objects in various testing conditions can be measured at the same time, the lift and the drag can be turned into numerical values, and the lift-drag ratio can be calculated based thereon so that performances of the objects can be analyzed efficiently.
