Data Interoperability for Aerospace IVHM Systems 2019-01-1342
Aerospace systems today are generating a lot of data and for the most part all this data is being generated by siloed entities (by various stakeholders like components/sub-system manufacturers, OEMs, operators) and ends up living within the four walls of these individual entities. For the industry to fully benefit from this data there needs to be a transparent way to share this data while strictly controlling the proprietary nature of the data and adhering to all contracts. The SAE HM-1 technical committee is writing an aerospace information report (AIR) to describe a digital data landscape and approach that can support health management. Integrated vehicle health management (IVHM) systems can specifically benefit from having a more structured landscape because their systems cut across many boundaries. For example, data associated with a fault in an aircraft subsystem like the engine must travel through multiple systems and boundaries before it can be analyzed by the cognizant personnel. Today the landscape is pretty ad-hoc; with not many standards governing the data handling, storage, analysis, and disposal. This information report is the small beginning in describing how a more systematic way of structuring the interactions might make the job of dealing with all this data a little easier. In this paper we are summarizing this AIR – that is currently being balloted and will be published by the time the conference takes place – in the hope that a wider audience can be introduced to its main thesis. An added benefit would be to get feedback from this audience in order to improve the document in subsequent revisions.
