Distributed Engine Control (DEC) Technology helps achieve these objectives by creating and advancing the control system hardware technology to overcome engine system constraints which prevent the acceptance or optimization of many new engine technologies.

DEC Objectives:

  • Create a sustainable high temperature electronics infrastructure which will allow growth and integration of new control system technologies thus enabling a pathway to new engine technologies consistent with VAATE goals.
  • Create new tools which advance and help validate soft and hard control technologies which improve vehicle performance metrics and reduce specific energy consumption.

Objective: Modular, Open, Distributed Engine Control

Technology Benefits

  • Increased Performance
    • Reduction in engine weight due to digital signaling, lower wire/connector count, reduced cooling need
    • 5% increase in thrust-to-weight ratio
  • Improved Mission Success
    • System availability improvement due to automated fault isolation, reduced maintenance time, modular LRU
    • 10% increase in system availability
  • Lower Life Cycle Cost
    • Reduced cycle time for design, manufacture, V&V
    • Reduced component and maintenance costs via cross-platform commonality, obsolescence mitigation
    • Flexible upgrade path through open interface standards
