Automated Contingency Management for Advanced Propulsion Systems  

Impact Technologies, LLC.  

Rochester, NY 
 

INNOVATION 

Impact Technologies in collaboration with the Georgia Institute of Technology and Pratt & Whitney Rocketdyne, developed multiple tools and techniques to facilitate Automated Contingency Management design for Propulsion systems (PACM). ACM is a term used to describe a philosophy whereby both diagnostic and prognostic information is linked with control functions to mitigate the impact of incipient failures on the operational integrity of a failing system for the duration of a mission.

• A Matlab/Simulink based Test Bench for ACM model development
• A toolset for ACM validation and verification
• Utilities for integrating NASA’s Livingstone2 (L2) software with Matlab and for generating embedded Livingstone reasoners
• Simulation based fault simulation and anomaly detection for the SSME facilitated by a subcontract to Pratt and Whitney Rocketdyne
• A generic monopropellant system model in Simulink (instantiation of the ACM Test Bench) with an ACM case study
• Innovative, optimization-based approaches to linking prognostics and hierarchical control

COMMERCIALIZATION 

• Products: Embedded L2 Reasoner; L2 Matlab Interface toolbox
• Service: embedded diagnostic and recovery reasoner design for propulsion systems
• Primary target market sectors: propulsion and commercial aircraft industry, satellite and spacecraft health management
• Products/service currently available for sale

• Applicable to all space platforms, all Unmanned Systems (UMS) within the DoD as well as industrial manufacturing applications highly dependant on autonomy.
