Abstract
Compacted snow runways for heavy wheeled aircraft are challenging in polar regions and possible extraterrestrial infrastructure constructions. A finite element method was successfully employed to simulate a wheel landing on layered snow using the ABAQUS software package based on the Phoenix runway in Antarctica. First, the method was validated with theoretical results of several layered systems. Thereafter, basic parameters of snow were chosen with reference to the Phoenix runway's pavement. Stress distributions under landing gear were calculated for the C17, A319, B757 and Il-76 aircraft. Furthermore, the effect of subgrades on stress distributions were discussed. This study explores current knowledge on snow pavements and provides technical support for the design and construction of compacted snow runways.
