Definition of optimum parameters the system loading control of aircraft at life tests on the mathematical model

It is described the problem of definition the optimum parameters of the control law of loading the aircraft in carrying out life tests. The research is investigated on the computer models of stand tests aircrafts Tu-154 and Tu-204. The validity of results is confirmed by their comparison with data of actual test. The results of research showed, that the computer model allows to determine the optimum parameters of loading systems taking into consideration elastic properties of aircraft and other parameters of test stand at the designing stage of aircraft.
