“…The material used in aircraft landing gear components by various manufacturers is mentioned and the airworthiness regulations checklist, which lists the prerequisites and limitations for the FEA approach for passenger aircraft landing gear for structural and fatigue safety by S.G. Aftab and his co-authors (Aftab et al, 2022). The effect of increasing aircraft landing weight on tyre performance, landing weight causes stress propagation and tyre deformation, which may result in tyre tearing and blowouts, which airlines should avoid by aircraft damage and crashes (Essienubong, 2018). James N. Daniels performed numerical simulation and experimental study to validate the landing gear equation of motion during action (Daniels, 1996).…”

Landing gear failures are a major cause of aircraft failures because they are an integral part of the aircraft's development. According to the Federal Aviation Administration (FAA), 50% of all aircraft failures occur during take-offs and landing. The landing gear of a short take-offs and landing (STOL) aircraft has had its static and dynamic forces analyzed analytically and numerically. SOLIWORKS is used to model the landing gear, and ANSYS is used to perform the numerical simulation results. Following it, the model is examined for stress and deformation with the boundary conditions and computed loads into account. This study uses structural finite element analysis (FEA) to analyze the nose gear's stress behavior and displacement during landing, as well as to assess the effect of the runway gradient. Utilizing a comprehensive numerical simulation, the landing gear of a real material Twin-Otter STOL aircraft has been demonstrated to be subjected to a dynamic force of 3653.26N, a pneumatic pressure of 1.59MPa, a bead pressure of 7.97MPa, and a vertical force of 1672.31lbs on level runways, or runways with no gradient. These findings will increase the level of confidence of aircraft manufacturers to make necessary appropriate design of STOL aircraft’s landing gear. It may can decrease the aircraft accidents and increase human life safety ultimately saving valuable time and resources too.

“…However, there is variation in kinetic energy absorbed. The influence of aircraft weight on the tyre behaviour during aircraft landing phase was investigated by Essienubong et al (2018). The authors concluded that overloaded airplanes may negatively affect the aircraft tyre during the landing phase of the aircraft in terms of stress deformations and build up.…”

The aim of the research described in this paper is analysis of the deformation of the aircraft tyre subjected to static load. Based on the results of experimental tests with a different value of inflation pressure, favorable pressure conditions for use in the tyre of an ultralight aircraft were determined. The deflection characteristics of the tyre depending on the nominal pressure was determined using the digital image correlation technique. In the range of loads not leading to excessive tyre deflection, quite linear relation between vertical deflection and vertical force is observed. The safe minimum pressure in tyre loaded with a force of 12 kN is 2.5 bar. The experimental results will be used to select a shock absorber for a 600 kg ultralight, light sport aircraft commercialised by the company Ekolot (Krosno, Poland).

“…Yao et al (8) established a detailed finite element model of an aircraft tyre based on the target tyre's actual geometry for dynamic numerical simulations. Essienubong et al (9) established a three-dimensional finite element model of a tyre using the finite element tool LS-DYNA and investigated the effect of increasing the landing weight on the tyre performance. Zhang et al (10) coupled smoothed particle hydrodynamics and the finite element method in LS-DYNA to carry out research work on aircraft tyre spray.…”

Numerical and experimental testing of aircraft tyre impact during landing

et al. 2021

The capability of aircraft tyres to sustain landing impact loads is essential for flight landing safety. Hence, the development of a reliable experimental database is necessary to validate numerical models. The experimental data on aircraft tyre landing impact in the public literature are somewhat sparse. This paper describes a detailed design rig for aircraft tyre impact testing. A finite element model is then created and simulated using a finite element tool (ABAQUS). Inflation and static load simulations are analysed based on the FE tyre model to confirm its reliability. Comparison of experimental measurements with the results reveals that the model can predict the significant features of aircraft tyre impact in a landing scenario. Very little experimental data are publicly available to verify aircraft tyre models. Therefore, the experimental data in this paper fill this gap in the literature.
