Landing skids are an important component of uncrewed helicopters. The landing skid acts as a support when the helicopter lands or is parked. This paper examines the effect of landing speed and material selection on the safety factor of uncrewed helicopter landing skids using Ansys Workbench. The uncrewed helicopter weighs 100 kg and an impact time of 0.5 seconds. Landing speed variations are 2 m/s, 3 m/s, and 4 m/s. The materials used in the simulation are plastic types, namely ABS, HDPE, Polyamide (PA6), and Polycarbonate (PC). The simulation results show that the ABS and HDPE materials can only withstand impact loads up to a landing speed of 3 m/s because they have a safety factor of 3.57 and 3.69, respectively. Meanwhile, Polyamide (PA6) and Polycarbonate (PC) can withstand impact loads up to a landing speed of 4 m/s because they have a safety factor of 4.19 and 6.03, respectively

“…For many aircrafts, the emergency deployment procedure consists of unlocking the landing gear from retracted position, and then, the landing gear deploys upon its own weight. In [12][13][14], there is the analysis of the optimized design and landing gear load. Modern solutions for landing gear health monitoring are in [15].…”

This work presents two versions of landing gear drives numerically simulated. We follow to obtain the right driving sequence of the legs and doors and the estimation of the landing gear deploy and retract time. Although the studies in this paper do not exhaust all the aspects concerning landing gear hydraulic system functioning, these are useful in the design phase of the aircraft hydraulic systems. Regarding the landing gear hydraulic system, we highlight one version of the drive stall phenomenon. When the hydraulic feeding pressure decreases, it is possible that the forces developed by the hydraulic cylinders are enough to retract completely the legs. The landing gear remains in an intermediate position, and the aircraft cannot accomplish its mission safely. For a second version, logic command functions are synthesized using Karnaugh diagrams, and after that, the numerical simulation is accomplished to validate the solution. We used the AMESim software to perform numerical simulations.

“…The landing gear is an important device to support aircraft take-off, landing, taxiing, and parking, to bear and relieve the effect of impact forces on the aircraft in the above processes, which is an indispensable device for aircraft [1][2][3]. Most modern aircraft use retractable landing gear.…”

The design of the retraction mechanism is an important part of landing gear design, and optimizing the space retraction mechanism is extremely difficult. An intelligent optimization model of landing gear retraction based on physical simulation is established to investigate further the recently proposed innovative design method for landing gear retraction trajectory. The theoretical kinematic model is combined with a collision detection algorithm to realize the interference check during landing gear retraction. An intelligent algorithm uses the minimum clearance between the landing gear and cabin segment as the evaluation index to optimize the key retraction parameters. The results of the optimization case show that the physical simulation model based on the Devillers algorithm established in this paper can effectively guide the intelligent design of key parameters of landing gear retraction.
