NASA Glenn Partners with Cleveland Hopkins International Airport and Commercial Carriers to Advance Knowledge of Aircraft Emissions
Production of cleaner, more efficient airplane engines is the ultimate goal of experiments to be conducted by NASA and its industry partners at Cleveland Hopkins International Airport.

Extensive airplane emissions data will be gathered as a result of cooperation among NASA's Glenn Research Center, Cleveland Hopkins International Airport, Continental Airlines, Continental Express Airlines and FedEx Express. During the collaborative effort, as part of the Aircraft Particle Emission eXperiment 3 (APEX3) Project, engine exhaust and plume development will be studied by acquiring data from behind parked aircraft. Exhaust dispersion during normal operations will be studied by acquiring data downwind of nearby taxiing aircraft and those taking off.

"We are excited about being able to conduct these tests right in our backyard," said Dr. Chowen Chou Wey, APEX Project Manager and Environmental Assessment Specialist in the Vehicle Systems Project Office at Glenn. "Working with our next-door neighbors Cleveland Hopkins, Continental and FedEx Express will bring our work in attaining the APEX objectives closer to home."

The tests at Cleveland Hopkins are part of a national effort to study aircraft particulate emissions using a variety of aircraft. Cleveland's testing is the first to include small jets and large cargo aircraft. The industry partners are supplying regional jets (ERJ 135/145 - Continental Express), commercial jets (Boeing 737 and 757 - Continental) and wide-body aircraft (A300-600 - FedEx Express).

"We are pleased to work with NASA Glenn, Continental Airlines, Continental Express and FedEx Express on this important project," stated John C. Mok, Director, Cleveland Airport Systems. "Since operational costs are of paramount concern to all of us, the data gathered will be instrumental to the future success of every facet of the aviation industry. We applaud NASA Glenn and stand ready to assist in any way we can. Overall, this project is an excellent example of many levels of partnership coming together for the ultimate good of everyone."

Test dates for parked aircraft are scheduled to begin this Sunday, October 30, and continue through November 9.

Cleveland Hopkins International Airport (CLE) is one of the nation's leading air travel facilities, offering service to more than 11 million passengers on more than 260,000 flights annually. Founded in 1925, CLE supports approximately 9,500 on-airport jobs and serves more than 80 nonstop destinations daily. The City of Cleveland owns and operates CLE and Cleveland Burke Lakefront Airport. Both are committed to offering safe and efficient air service to the Greater Cleveland area while providing excellent services and facilities to the traveling public.

NASA's Glenn Research Center, with about 3,300 civil service and contract employees, is a key research center for aeronautical propulsion, space propulsion, space power, space communications and microgravity sciences in combustion and fluid physics. The center consists of 24 major facilities and more than 500 specialized research facilities at a 350-acre site near Cleveland Hopkins International Airport, and the 6,400-acre Plum Brook Station in Sandusky, Ohio.
