Wind-Tunnel Investigation of Air Loads on Human Beings.

摘要

An investigation was conducted in the Taylor Model Basin 8- by 10-foot subsonic, atmospheric Wind Tunnel 2 to determine the drag coefficient of man. Tests were made at several yaw angles with subjects of various sizes in five body positions: standing, sitting supine, and two squat positions. Data were obtained for the subjects in both the clothed and nude conditions. A parameter was formulated from the available physical characteristics of the subjects tested and all coefficients were based on this. Drag coefficients were obtained which shoud be reliable in predicting drag forces on men of average stature under a variety of conditions. Lift, side force, and moments were also obtained which indicate relative trends of motion for each position. (Author)
