Available in PDF, EPUB and Kindle. Book excerpt: The objects of the report are to increase the knowledge of the physical and optical properties of ice fog and to develop techniques for its dispersal. Two series of flight tests to determine the effects of CH-47 helicopter downwash on ice fog were conducted near Ft. Wainwright, Alaska, in January 1971. During the first series, clearings were produced which were large enough for helicopter operations. This series of tests was conducted when the ice fog was in a dissipating state. The second series of tests was conducted in a denser ice fog during its developing stage. The same flight procedures were used, but clearings were not produced. (Author).

Book excerpt: Results of helicopter clearing experiments conducted at the Greenbrier Valley Airport, Lewisburg, West Virginia, during the period 7 to 29 Sep 1969, are presented and discussed. Thirty-five hover experiments and runway- clearing experiments were performed on 10 separate days with fog layers ranging from 125 to 525 ft in depth. The hover experiments, which were successful in virtually all cases, yielded clearings that varied from 400 to 2800 ft in length extent. The largest clearings occurred with the shallowest fog during tests conducted within one hour or so of the natural dissipation time of the fog. The runway-clearing experiments were successful in clearing the full 6000 ft extent of the runway on two occasions, were partially successful on four occasions and were unsuccessful on 12 occasions. Six helicopter landings were accomplished through artificially-created clearings. Quantitative information is described concerning the wake penetration distances of the helicopters, the steady-state clearing times, the total entrainment (mixing) values and the persistence times of the clearings following helicopter departure from the test sites. The temperature, humidity and wind speed values within the cleared zones are also given for certain of the experiments.
