چکیده
Corresponding author: Honeywell CA35, 1 Results Way, Cupertino, CA 95014; e-fax: (208) 545-6408; e-mail: [email protected], [email protected], Abstract. This paper describes a case study of modelbased diagnostics system development for an aircraft Auxiliary Power Unit (APU) turbine system. The offline diagnostics algorithms described in the paper work with historical data of a flight cycle. The diagnostics algorithms use detailed engine systems models and fault model knowledge available to Honeywell as the engine manufacturer. The developed algorithms provide fault condition estimates that allow for consistent detection of incipient performance faults and abnormal conditions.

Novel Auxiliary Power Unit Configuration Based On Fuel Cell Technology for Civil Aircraft Application
This paper proposes novel Fuel Cell Auxiliary Power Unit (FCAPU) for J150+ aircraft application. The primary version of APU in J150+ aircraft is a gas turbine Auxiliary Power Unit (APU) which is based on gas turbine jet engine but in the suggested FCAPU, the generated electrical power is achieved from chemical energy with higher efficiency. The Solid Oxide Fuel Cell (SOFC) technology is used to...
