Model helicopter-type aircraft landing control on a water body with snow-ice cover

This article deals with the problem landing a helicopter-type aircraft on an unprepared site, in particular, a model landing control on a body water with snow and ice cover is proposed. The analysis the standard means landing, installed on helicopter - type aircraft, has now shown that in Arctic conditions they are not able to provide the crew with information about the underlying surface (landing site) such as the depth snow and the thickness the ice cover. Simulation the process landing control helicopter aircraft on an unprepared site on a body water with snow and ice cover with the proposed radar landing system showed that the task can be successfully solved. To do this, the underlying surface (landing site) is probed and information is given to the crew about the possibility landing, or lack thereof, comparing the measured values with those specified for a particular type aircraft. The paper presents a logical information model that reflects the automation the landing control process by assessing the possibility a safe landing, by radar determination the parameters and characteristics flat-layered media, snow depth and ice thickness. The use the model is possible in the development radar systems to ensure the safe landing a helicopter - type aircraft on an unprepared site with snow or snow-ice cover in conditions insufficient information about the underlying surface.
