To an issue of rating the external loads on a helicopter with skid landing gear for landing loading condition

The existing technique of rating the external loads on a helicopter with skid type landing gear according to Airworthiness Standards [1] is analyzed and the results of comparing with design and experimental studies are presented. The main existing problems both in design simulation and the system of requirements to the conditions of rating the loads on the skid landing gear helicopter are identified. Also proposed are the techniques to increase safety of the helicopter emergency landing by refining the rating conditions of external loads at the design stage.
