DOWNWASH IMPINGEMENT DESIGN CRITERIA FOR VTOL AIRCRAFT
Abstract
The objective of the program was to utilize existing data for the preparation of design charts for VTOL aircraft to aid in the establishment of aircraft designs that will alleviate the adverse operational conditions resulting from downwash impingement on terrain. Specific areas of investigation included particle entrainment and ingestion and their effect on pilot vision, aircraft damage, personnel injury, and aircraft signature. Methods to quantitatively predict operational conditions resulting from downwash impingement of a VTOL aircraft are presented.
