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. © 2012 Allerton Press, Inc.

A single-rotor helicopter with the Ansat-type tail rotor is considered. We solve the problem of synthesizing a correcting law of autopilot control with the use of a observer that permits the quality of stabilizing the specified flight regimes to be improved and pilot's functional stress to be lowered. © 2012 Allerton Press, Inc.

A new approach to the design-systematic provision of autorotation landing safety for a helicopter with skid type landing gear is proposed. We analyzed the existing simulation techniques and experimental studies regarding this problem. The main existing problems both in design simulation and the system of systematic requirements to the conditions of rating the loads on the skid landing gear are identified. Also proposed are the most optimal solutions to overcome the existing systematic contradictions and increase safety of helicopter piloting at autorotation landing. © Allerton Press, Inc., 2012.
