Estimation of Load Exceedances of an Aircraft under Carriage with Nonlinear Properties Excited by Random Runway Unevenness

摘要

Methods to describe a landing gear with nonlinear properties excited by random runway unevenness during taxiing were investigated. Calculations were compared to measured results from an analog computer simulation. The mean behavior, standard deviations, and power spectra can be described with a classic type of equivalent gain. Load exceedance curves can be approximated fairly well with conditional equivalent gains that depend on the output load level.
