The technical state statistical evaluation of the aircraft structures components according to the flight tests information

摘要

Statistical determination methods of the full operating time parameters distribution for aircraft structures as to evaluate their technical state during maintenance are considered. By the example of information about breakdowns revealed during operating of the 42 same type aircrafts with increased operating load level the analysis of safe limit operating time for zones and elements of aircraft structures is performed. Determination methods of confidential limits for distribution parameters evaluation in case of single- and multiple-censorized samplings are considered. Calculations are in the Mathcad environment performed.
