WIND TUNNEL TEST MODEL AND WIND TUNNEL TEST METHOD

摘要

The purpose of the present invention is to provide a wind tunnel test model which can be supported without disturbing wind conditions around a half model and thereby implement a wind tunnel test for an antisymmetric mode flutter phenomenon with high precision. A wind tunnel test model (1) is provided with a half model part (3) which imitates the fuselage of an aircraft and a single wing, and a support device (5) which supports the half model part (3) rotatably about a central axis line (CL) at a position away from a wind tunnel wall, the support device (5) extends backward with a cross-sectional shape approximately the same as or similar to the fuselage (7), and is provided with, on the rear end side thereof, a securing part (11) for securing the half model part (3) to the wind tunnel test device side, and provided with, in a housing, a torsional rigidity application means for applying predetermined torsional rigidity about the central axis line (CL) to the half model part (3).
