AIR VELOCITY DISTRIBUTION BEHIND WING-MOUNTED AIRCRAFT ENGINES

During the deicing of the tailplane of large aircraft, deicing trucks frequently pass behind the exhaust of wing mounted jet engines. Major concerns regarding the stability of these vehicles are the high air velocities and associated forces developed in the vicinity of jet engine exhaust plumes. The focus of the research reported here was to obtain working spatial distributions of these air velocities and to better understand their effect on deicing truck stability. The report contains results of research conducted in 1998-99 related to air velocity distribution in the vicinity of aircraft tailplanes, the overturning loads experienced by deicing trucks due to engine blast and air velocity distribution in the vicinity of the Boeing 777 auxiliary power unit. 19 tests were conducted on nine different aircraft models during five test sessions at Montreal, Toronto, and Atlanta airports.
