TURBOCLAIR FOG DISPERSAL METHOD: DEVELOPMENT AND TESTING OF UNDERGROUND BLOWER UNIT (1965-1969).
Abstract
A testing program to evaluate the Turboclair fog dispersal method has been completed at Orly Airport, Paris, France. The program included evaluating underground turbojet engine design and performance, determining the optimum location and orientation of the underground unit relative to a runway, and obtaining data on the unit's functional contribution to fog dispersal. The Turboclair method involves using underground turbojet engines to heat air along runways in order to cause evaporation of water droplets in fog and thus increase visibility. The effectiveness of heat from the engines was evaluated at Orly Airport through air temperature measurements and visual observations. The results of the test program confirm that the Turboclair method is effective on warm fog when air volumes are heated by the engines to 2C above ambient temperature. The size of the defogged space is determined by engine orientation as dictated by wind direction and intensity. From test results it is concluded that this type of installation is ready for implementation at an operational level at Orly Airport. (Author)
