Available in PDF, EPUB and Kindle. Book excerpt: As part of a broad effort by the Air Force to evaluate various methods of dissipating warm fogs over airport runways, a feasibility study has been made of the possible use of radiant energy to dissipate fog. The source of microwave power was considered either ground-based or airborne. For the ground-based case, the microwave beam was taken as parallel to the ground and along the runway, providing a direct source of microwave power for heating the fog. For the airborne case, the beam was taken as perpendicular to the ground, the heating of the ground by the microwave beam providing a source of infrared power for dissipating the fog. The study showed that, for either case, very large power densities, well above the personnal safety limit of 100 W/sq m used in the U.S. would be required to dissipate the fog in a time of about 10 min. If the power density is taken as 100 W/sq m, a very long time, that is, many hours, would be required to dissipate the fog. In addition, because of the high cost of electrical energy, the large amount of energy required to dissipate a typical airport fog (about 3 x 10 to the 11th power J) makes the scheme prohibitively expensive.

This book was released on 1975 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: This engineering study determines the feasibility of and prepares a conceptual design for a ground-based warm fog dispersal system at a selected airport which has a high frequency of fog and a large air traffic volume that is adversely affected by fog. Los Angeles International Airport (LAX) was selected as the airport for study. The study considers and includes a brief review of warm fog dispersal mechanisms. The results indicate that heat is presently the only reliable technique for warm fog dispersal. Two methods of applying heat to fog are examined in detail, namely, the Thermokinetic and Modified Passive Thermal. Engineering costs estimates are developed. The results of the study indicate that both systems would be cost-effective at Los Angeles International Airport. For improving the visibility in fog to CAT 2 minimums, the 12-year benefit-to-cost ratio of the Thermokinetic Fog Dispersal System which uses natural gas for fuel is 8.7 to 1 while the Modified Passive Thermal Fog Dispersal System has a ratio of 4.8 to 1. The study concludes that a Thermal Fog Dispersal System at LAX is both feasible and cost effective.
