Higher-order statistical analysis of stability upsets induced by elevator horn icing. 10.2514/6.2009-3770 Volume AIAA 2009-3770. 2009.
abstract   bibtex   

The impact on stability and control of small general aviation aircraft, resulting from ice accumulation on the elevator horn balance, is investigatedusing an experimental data set. The purpose is to determine the linear and non-linear coupling mechanisms between the ice-induced unsteady flow field and the structural response of the elevator horn balance. The linear and quadratic relations between the two unsteadysystems are obtained by employing higher-order statistical signal processing based on a non-orthogonal, second- order, single-input/single-output Volterra model. In this way the frequency- and angle of attack ranges, for which lock-in occurs, are identified for di!erent ice configurations on the leading edges of the elevator horn balances and its deflection angle.
