Introduction

0.1 Goals This document has been developed for the needs of the analysis and calculation of single event effect failure rates for avionics electronic products. 0.2 Technical overview Avionics equipment working in the atmosphere, its key devices will produce a variety of single-event effects under the radiation of atmospheric neutrons, which are transmitted to the atmosphere. Avionics, which can produce single event effect soft and/or hard faults, can affect the safety of the aircraft. Considering that only device-level SEE Only the failure rate participates in the safety analysis process at the system level and the aircraft level. Therefore, it is necessary to provide equipment-level information in the process of aircraft safety assessment. The SEE failure rate and its calculation method and program provide basic data for the safety analysis of avionics equipment. GB/T 34955-2017 "Guidelines for Single Event Effects Tests of Atmospheric Radiation Affecting Avionics Systems" and GB/T 34956-2017 "Guidelines for the Design of Single Event Effect Protection for Avionics Influenced by Atmospheric Radiation" together constitute the design of single event effects for avionics products Basic technical standards with analysis. GB/T 41270 specifies methods and procedures for the analysis, testing and evaluation of atmospheric neutron single event effects, and is intended to consist of two parts. --- Part 7.Process management of single event effects analysis in avionics product design. The purpose is to specify avionics product design Methods and procedures for single event effect analysis of electronic components. --- Part 9.Avionics equipment single event effect failure rate calculation procedures and methods. The purpose is to specify the avionics list Particle effect failure rate general, total failure rate, soft failure rate, hard failure rate calculation method and calculation program. 0.3 Description of relevant patents The issuing body of this document draws attention to claims that compliance with this document may relate to single event effect failure rates, atmospheric neutron radiation stress, Use of patents related to device sensitive cross-section and derating factor.
