Helicopter HOGE Capability Assessment Through Climatology Modeling
Abstract
This paper presents an updated examination of the United States Army's hover out of ground effect performance criterion for helicopters. This requirement has been the subject of controversy since its initial issue during the 1950s due to cost and weight constraints in a helicopter's design. Over the succeeding years, various studies produced contradictory recommendations as to the most appropriate temperature and altitude combination for use in specifying global helicopter operational capability. Modern climate models can provide data for a greater number of locations around the world than was available in the past. By coupling this data with a helicopter's design point performance, it is possible to visualize a helicopter's operational capability in terms of worldwide distribution of temperature and pressure altitude mean averages and extremes. It is thus possible to graphically understand the design trade space and to tailor the helicopter's operational capability for specific geographic regions.
