Operational Requirements Document (ORD) CAF 315-97-B calls for the development of a Personnel Recovery Vehicle (PRV) to be used during Combat Search and Rescue missions undertaken by the Special Operations Command. Tests were conducted in the Aerospace Vehicle Survivability Facility of the 46th Operation's Group's Munitions Test Division (46 OGM), WPAFB to determine the horizontal and vertical airflow velocity limits in which personnel can perform necessary tasks. Horizontal test profiles included subjects walking into airflow wearing representative gear and carrying a Stokes litter with a patient. Vertical tests included descending a fast rope, climbing a ladder, and hoisting a litter into the airflow. Data analysis resulted in definition of horizontal airflow velocity limits. Vertical airflow limits were not defined due to poor experimental flow conditions. Horizontal flow is the limiting factor operationally as it is much stronger than vertical flow.
