Abstract: The inducement of cloud glaciation by cooling with evaporating droplets of liquefied propane was investigated in laboratory experiments and in field tests. The efficiency of ice crystal production was shown to be near 1012 ...

Abstract: Experiments have been performed under controlled and free environment conditions to determine the technical feasibility of using the cooling resulting from the adiabatic expansion of compressed air to initiate ice crystal ...

Abstract: Results of helicopter clearing experiments conducted at the Greenbrier Valley Airport, Lewisburg, W. Va., during the period 7?29 September 1969, are presented and discussed. Thirty-five hover experiments and 18 runway-clearing ...
