Patent ID: 11402300

Abstract:
The present invention provides blade structure testing equipment comprising: a mounting jig to which one end of a blade specimen is mounted; a grip member to which the other end of the blade specimen is coupled; and a wire (W) having one end attached to the grip member to apply a tensile force to the blade specimen in a direction at a certain angle with respect to the ground. Also, the present invention provides a method for testing a blade specimen, the method comprising: a first step of coupling one end of the blade specimen to a mounting jig and the other end of the blade specimen to a grip member; a second step of determining the values of a centrifugal force, a flap moment, and a lag moment that are to be applied to the blade specimen; a third step of determining the magnitude and direction of a tensile force to be applied to the blade specimen, on the basis of the values determined in the second step; and a fourth step of attaching one end of a wire to the grip member and applying a tensile force to the blade specimen by means of the wire at the magnitude and in the direction of the tensile force determined in the third step.
