Concorde emissions at Dulles International Airport--results of measurements

OSTI ID:5178427
This report on published studies made by the U.S. Federal Aviation Administration for the U.S. Department of Transportation examines May 1976-May 1977 data (on the monitoring of the carbon monoxide and nitric oxides during the taxiing, engine start, and takeoff of the Concorde on the airport grounds and about one mile from the airport boundary) that showed that all off-airport measurements could be adequately explained by regional variations in air quality that were independent of airport activities; considers data which showed that the Concorde emissions apparently dispersed to undetectable levels within 2000 ft of the aircraft, and that carbon monoxide emission rates were lower by a factor of three than published emission rates derived from engine test measurements; indicates that the cause of these reduced concentrations may be the turbulence of hot jet exhaust gases and the rise of the emission plume; and points out the weaknesses of the Landing-Takeoff Cycle assumptions.
