Ames Prognostic Hardware to be Included in the Third Phase of Armstrong’s Vehicle Integrated Propulsion Research Project

George Gorospe (Code TI, SGT Inc.) will travel to Armstrong Flight Research Center to operate Ames-developed prognostic hardware during the third phase of the Vehicle Integrated Propulsion Research (VIPR) project. During testing, this hardware will introduce and control the progression of a fault in the variable bleed valve system of a Pratt and Whitney F117 engine integrated with a C-17 military transport aircraft. This test will benefit the development of prognostic software in assisting operators with decision making for scheduling and maintenance.

BACKGROUND: Demonstration of propulsion health management technologies is critical for their commercial acceptance. A major aspect of ongoing NASA propulsion health management work is demonstration of these maturing technologies on an operational engine in a series of VIPR tests. VIPR is a means to test and evaluate emerging health management technologies on a commercial engine, incorporating new sensors directly onto the engine, providing seeded fault scenarios, and evaluating advances in engine diagnostics. This step is critical in order for Integrated Vehicle Health Management (IVHM) technologies to mature from lab work and simulation demonstrations needed for industry acceptance. This work is in partnership with the U.S. Air Force, which has provided access to two F117 high-bypass turbofan engines and time on operational planes for the ground-based onboard engine tests.

COLLABORATORS: This work is a collaboration between NASA Ames Research Center, NASA Armstrong Flight Research Center, and the U.S. Air Force.
