Wind tunnel testing apparatus for simultaneous measurement of drag force and lift force

The present invention relates to a wind tunnel test apparatus capable of measuring the lift and drag forces generated by the shape of the various objects, angle of attack, wind speed, the Reynolds number at the same time, to effectively analyze the lift and drag forces and yanghang ratio (lift / drag). The present invention, by implementing the wind tunnel structure, the lifting load cell and the conjunction of the drag load cell combination, a new type using such as a computer for evaluating the measurement values ​​of the wind tunnel test apparatus capable of ensuring a uniform flow rate by the rectifier for the fluid, a variety of experiments as well as to measure the lift and drag forces generated in the body under the conditions at the same time, evaluating the lift and drag, and by calculating the yanghang ratio through which to measure the lift and drag forces that can efficiently analyze the performance of an object at the same time It provides a wind tunnel test apparatus.
