Abstract Keywords
In this article we consider the design of experiments (DOE)
algorithm for an aircraft with landing gear on air cushion.
For the purpose of this research we carried out two types of
experiments: static and quasi-dynamic. Taking into account
the difference of surfaces, this work offers two mathematical
models for static and quasi-dynamic events. In order to
build multi-factor regression models we conducted 24 ex-
periments for the quasi-dynamic test and 12 for the static
test. Further, the parameters of accuracy and adequacy of the
non-linear multivariate model of the first order were not
sufficient, thus it was necessary to increase the order of
polynomials. The higher the order of polynomial approxi-
mation is, the more accurate the original mathematical
model becomes. For a given air-cushioned aircraft landing
gear the second order polynomial was sufficient to verify the
reliability of the data obtained
