The Stability of a Wind Tunnel Model on Flexible Supports

Published online by Cambridge University Press:  04 July 2016

Extract

A convenient aid to the investigation of the aeroelastic properties of aircraft is provided by wind tunnel tests on scale representative aeroelastic models. A wide variety of tests is commonly made ranging from tests on models of component parts of an aircraft (wing, tailplane, fin, etc.) to tests on models of the whole aircraft. In many of these tests it is adequate to mount the model structure rigidly to the tunnel wall or sting, but in other cases the model must be provided with rigid body freedoms for representative results to be obtained. This is generally necessary for aeroelastic models of complete aircraft, and particularly for models of slender configuration.
