Evaluating Wind Flow Around Buildings on Heliport Placement.

ADA153512

Publication Date	1984
Personal Author	McKinley, J. B.
Page Count	45
Abstract	This report presents a heliport wind assessment method for evaluating and potentially minimizing the influences of building-induced wind on heliport operations. Descriptions and illustrations of wind flow patterns and characteristics for both isolated and multiple building configurations are provided to assist heliport planners, operators, and helicopter pilots in understanding the problems associated with building-induced winds. Based on geometric flow patterns, general guidelines for ground level and rooftop heliport placement are provided. Additional guidelines for determining the area of wind influence about isolated and multiple building configurations are detailed. Rules for calculating the distance from the sides of buildings for heliport siting is provided, as well as, rules for calculating the area of influence from any wind direction. Lastly, rules are defined for calculating the area of influence of buildings with respect to the prevailing climatic wind conditions. Recommendations are delineated for further data gathering and evaluation to validate and enhance the heliport wind assessment methods. Keywords include: Heliports, Turbulence, and Downstream wakes.
