“…8, although during simulation trials the markers were visible to the pilot through the HUD. Note that although the technology to implement this type of HUD does not presently exist for most helicopters, such a display could be implemented using a monocular cueing device such as that used in [27]. Additionally, Head Down Displays have been implemented in fixed wing aircraft for similar applications [19][20][21].…”

“…Hard landings can occur due to several factors, including poor weather conditions, poor visibility, over-loaded aircraft, mechanical/electrical failures, and pilot error. Research has been performed to mitigate the effects of restricted visibility on the pilot's ability to operate the aircraft [1][2][3][4][5]. Coltman, Bolukbasi, and Laananen examined the causes of over 1000 rotorcraft crashes within a 5-yr period [6].…”

A unique, beneficial feature of rotorcraft is their flexibility in aircraft-to-ground interfacing. For a variety of reasons, hard landings can occur when the descent rate of the aircraft is larger than intended. The resulting impact can result in vehicle damage, structural failure, injuries, etc. To reduce these risks, an attractive solution is the implementation of a robotic legged landing gear (RLLG) system. The system softens a hard landing by acting as a shock absorber with a relatively large stroke, allowing the aircraft to decelerate over a much larger distance compared with a tradition landing gear system. This paper explores the mitigation of rotorcraft hard landings via RLLG through a comprehensive multibody dynamics simulation tool. The purpose of this study is to demonstrate the efficacy of the RLLG as a robust solution to reduce loads during hard landings for multiple landing configurations. The results show that when using RLLG in place of conventional landing gear, peak loads are reduced by approximately 70–90%, depending on the landing conditions. Through Monte Carlo simulation, robotic landing gear system performance is shown to be robust to uncertain conditions.
