Data Concentrator for Modular and Distributed Control of Propulsion Systems

Orbital Research proposes to develop, build and test a high temperature Data Concentrator Module for use in distributed turbine engine control at high temperatures. The concentrator receives analog and digital signals related to turbine engine control and communicates with a FADEC or high level command processor. This data concentrator is follows the road map put forth by DECWG for use in creating a demonstration platform for turbine engine distributed controls communication development that operates at temperatures at least up to 225<SUP>o</SUP>C.The goal of Phase I is to develop detailed specifications for each component needed for the system, as well as to define the total system specification. This will entail a combination of system design, compiling existing component specifications, laboratory testing, and simulation. The results will show feasibility of the data concentrator. Phase II of this program is will focus on three key objectives: The first objective will be the detailed design, fabrication and testing of three new high temperature ASICs. Secondly software necessary to demonstrate operation the prototype will be developed. Finally integration of the components and software into a prototype high temperature Data Concentrator Module will be completed to demonstrate operation of the complete system in a realistic environment.
