摘要

DERA Boscombe's experience in the field of clearing military rotorcraft for operation in snow and icing now spans almost 40 years, with virtually all UK Military helicopter types having undergone at least one winter season testing in these conditions at sites in North America or Europe. This paper will provide a little historical information based on my own recollections and involvement in these DERA trials and some undertaken by others. I shll include a very brief description of the difficulties we have found operating helicopters in snow and icing and will then given an insight into some of the more interesting findings, test techniques and instrumentation used. Such techniques and instrumentation were developed and employed by DERA to improve our understanding of the conditions and the affects on the aircraft in order to reduce the risk asociated with any icing or snow flying clearance granted. The paper will then pose a few questions that stem from fixed and rotary wing aircraft incidents and accidents that have occurred in recent years. At its end, it will provide my personal "wish list" that perhaps if satisfied would enhance rotorcraft safety in snow and icing conditions; some of which may also have relevance to fixed wing aircraft.
