The DYC Turbines Team
Dr. Daih-yeou Chen
Dr. Chen earned his PhD from the University of California at Berkeley and has more than 30 years of experience in the Aerospace Gas Turbine Engine industry from Honeywell International Inc. and United Technologies Corporation (UTC), and specializes in gas turbine engine combustion, emissions, noise, high altitude ignition/starting and 3D CFD modeling. He was named a Chief Engineer in 1998 and awarded a Technical Fellowship in 2002 at UTC.
Dr. Chen designed and developed the industry’s first production effusion-cooled combustor (331-500) used on the Boeing 777 and won the Honeywell 1991 Technical Achievement Award. Also an expert on emergency power systems, Dr. Chen successfully developed a patented Tri-Mode combustor to integrate APU, ECS, and Emergency Power System into an Integrated Power Package (IPP) used on the F-35 Joint Strike Fighter. These accomplishments won 1st place in the Honeywell 1998 Quest for Excellence competition (an Innovation Award and an SBU Vision Award).
Dr. Chen was also a Chief Engineer with many years of experience in overall gas turbine engine design including system engineering for ETOP-proven high altitude ignition/starting, engineering/operations/procurement integration for supply chain management, and APU/Tailcone/Airplane integration for Chinese ARJ and Japanese MRJ programs.
