Research on Conceptual Design of Integrated Modular Avionics

Reliability and vulnerability problem of avionics is studied from the perspective of aircraft design. Integrated modular avionics (IMA) and federal avionics models are established. Reliability arithmetic for conceptual design stage is found and their reliability and vulnerability are calculated. Characteristics of both models are compared by means of analyzing the result, and it shows that reliability and survivability can be improved, meanwhile weight and volume of system can be reduced.
