Application of a dynamic vibration damper in aircraft models tested in a wind tunnel
This paper presents a method for safe testing of aircraft models equipped with a nonlinear dynamic vibration damper in a wind tunnel. The nonlinearity of the tested vibration damper is provided by an elastic element consisting in a package of thin flat springs. Nonlinear dynamic dampers of various designs are presented, along with the results of their application. It is experimentally shown that improved dissipative properties of the proposed elastic fastening of the model under test to the wind tunnel surface have a positive effect on the expansion of the range of admissible attack angles.
