Convergent Aeronautics Solutions' Prognostics-as-a-Service Prototype Scheduled to go Online August 18

The Convergent Aeronautics Solutions’ (CAS) Prognostics as-a-Service (PaaS) project, under the Transformative Aeronautics Concepts Program (TACP) in the Aeronautics Research Mission Directorate (ARMD), will bring the Prognostic-as-a-Service (PaaS) prototype online for the first time on August 18th. PaaS is a prototype platform for providing real-time failure prediction to any connected system remotely through a web interface. Once online, PaaS will be accessible via a web-accessible REpresentational State Transfer (REST) Application Programming Interface (API) for testing with systems seeking prognostics. The PaaS prototype was designed for use with Unmanned Aerial Systems (UAS), but is generalized so as to be capable of providing prognostics services to other aircraft, spacecraft, and ground systems. The prototype PaaS system will include a module for battery prognostics and a generalized Guided User Interface (GUI) for communication of results. Capabilities are expected to be expanded with further feasibility studies and use, through the addition of additional models, algorithms, and decision support tools. PaaS will be thoroughly tested in preparation for its use as a Supplemental Data Service Provider (SDSP) in the Unmanned Traffic Management (UTM) Technology Capability Levels 3 (TCL-3) test.

BACKGROUND: Prognostics is the prediction of system failures. The results of prognostics can be used to inform action to prevent failure and protect the safety of the vehicle, occupants, and the environment. Additionally, results can be used to enable condition-based maintenance, the scheduling of maintenance based on the physical condition of the system rather than on conservative schedule-based estimates of when systems statistically are likely to fail. This has the potential to greatly reduce maintenance costs. It is considered critical that future autonomous systems can accurately assess their health in real-time and predict failure.

Prognostics as-a-Service (PaaS) is a CAS-funded effort investigating the feasibility of creating a cloud service for providing system failure prediction and other health-based decision-making support. To assess the feasibility of this system, the ability to address the primary technical challenges of generalization, communication, security, utility, environmental complexity, and trust will be evaluated. Towards that end, the PaaS team is creating an initial prototype for a PaaS system to be demonstrated with the UTM TCL-3 flight test. This prototype will serve as the foundation for future feasibility assessment and applications.
