A Device for Measuring Low Damping Moments When Testing Models in Wind Tunnels,
Abstract
Unites are known for the measurement of low damping moments when testing models in wind tunnels and which are made in the form of a flat four-link mechanism which assigns the angular oscillations of the model being tested due to the kinetic energy stored by a flywheel. However, the sensitivity of such devices is insufficient. In the described device, to increase the sensitivity by means of a reduction in the natural dissipative forces the joints of the four-link mechanism are made in the form of two ball bearings arranged one inside the other whose outer race of the smaller ball bearing is put into rotation by a separate electric motor.
