Intelligent Life Extending Control

NASA GRC is pursuing development of both near term and long term technologies for extending the life of engine components through smart control. A near term technology development program is summarized in the above chart. It is anticipated that industry application of the above technology will result in Life Cycle Cost savings of $5-10M for a fleet of 400 engines for short haul aircraft.

Objectives

To demonstrate an advance control framework that can reduce damage and enhance engine life while meeting the performance requirements.

Approach

Develop Intelligent Life Extending Control (ILEC) methodology for near-term implementation using existing industry practices on damage modeling.

Accomplishments

  • AlliedSignal TFE731-20/40/60 engine selected as the demonstration platform
  • Conceptual design review held in Sept. 98
  • Preliminary trade study completed showing significant engine life cycle cost savings with ILEC
  • Partnership established with Allied Signal Engine to provide damage models, engine control logic, and FADEC hardware to implement ILEC logic.
  • Developed turbine damage model for FTE731-20/40/60
  • Simulate duty cycle of engine operation to determine effects of life and operation requirements
  • Developed control strategy
