Analysis of information sources in references of the Wikipedia article "Integrated modular avionics" in English language version.
Some believe the IMA concept originated in the United States with the new F-22 and F-35 fighters and then migrated to the commercial jetliner arena. Others say the modular avionics concept, with less integration, has been used in business jets and regional airliners since the late 1980s or early 90s
The core of the enhanced capabilities of the RAFALE lies in a new Modular Data Processing Unit (MDPU). It is composed of up to 18 flight line-replaceable modules, each with a processing power 50 times higher than that of the 2084 XRI type computer fitted on the early versions of Mirage 2000-5.
GE has developed a compute platform running an ARINC 653 partitioned operating environment with an Avionics Full Duplex Switched Ethernet (AFDX) network backbone. The CCS provides shared system platform resources to host airplane functional systems such as Avionics, Environmental Control, Electrical, Mechanical, Hydraulic, Auxiliary Power Unit, Cabin Services, Flight Controls, Health Management, Fuel, Payloads, and Propulsion.
The heart of the EASy platform is two, dual-channel, cabinet-based modular avionics units (MAUs). Highly rationalized, the MAU integrates functional cards for several applications into a single module. Each functional card performs multiple tasks previously requiring dedicated computer processors.
Biggest challenge within this area is that modular avionics is a composition of building blocks, preferably supplied by different companies in the supply chain. Each supplier is supposed to bring its part to a certain level of qualification, and after this a system integrator can use these "pre-qualified" part in the overall certification process.
Integrated Modular Avionics (IMA), based on standardised modules that can be shared by several functions. The IMA concept is very scalable, and delivers significant improvements in reliability, maintainability, size and weight.
