Tests were performed with an HH-3E, an HH-53B and an XC-142A to determine comparative downwash characteristics of the three VTOL aircraft. Simulated forest rescues were also made. Downwash velocities, sound pressure levels, temperatures, toxic hazards and relative freedom of movement of human subjects were measured and/or observed for various hover conditions. (Author)
