Description

Technical Field

[0001] The present invention belongs to the technical field of artificial polar ice and snow runways, and particularly relates to an artificial polar ice and snow runway simulation device and method. Background Art

[0002] The polar regions are rich in minerals such as combustible ice. In recent years, the scientific research work in the polar regions by various countries has become more frequent and on a larger scale, and the requirements for transporting materials, personnel, and equipment in the polar regions have also become higher and higher.

[0003] In recent years, various countries have generally used medium / heavy wheeled transport aircraft to carry out the transportation of materials and personnel in the scientific research work in the polar regions. The polar ice and snow runways required for the takeoff and landing of medium / heavy wheeled transport aircraft have extremely high requirements for the surrounding environment and heavy loads. However, there are very few naturally formed blue ice runways that meet the usage requirements, and almost all of them have been occupied. Building artificial polar ice and snow runways and realizing the aviation delivery capacity of medium / heavy wheeled transport aircraft have become an important means to achieve large-scale and high-efficiency resource operation in the polar regions.

[0004] China's scientific research work in the polar regions started relatively late and has less technical accumulation. Especially in the construction of artificial polar ice and snow runways, whether it is design parameters, technical means, or special construction equipment, etc., it is basically blank. There is an urgent need for an artificial polar ice and snow runway simulation device to test and verify the design methods, construction techniques, etc. of artificial polar ice and snow runways, improve the design level and construction level of China's artificial polar ice and snow runways, promote China to achieve aviation navigation of medium / heavy wheeled transport aircraft in the polar regions at an early date, and realize large-scale and high-efficiency resource operation in the polar regions of China.
