Description

[0002] Mobile aprons are the "capillaries" of the low-altitude economy's infrastructure. Through dynamic deployment and functional expansion, they solve the "last mile" problem of traditional aviation.

[0003] At present, most mobile aprons are modified from trucks. The tractor provides the power source, and the support system and trailer jointly bear the weight of the mobile apron and the impact of landing.
