Abstract

The invention relates to the technical field of air traffic, in particular to an eVTOL flying vehicle capable of folding and unfolding wings and suspending. The flying vehicle comprises a rectification shell, a power system, a cabin system, a wing folding and unfolding system and a nose landing gear system. The wing folding and unfolding and suspension are reused to take ground driving and air flying into consideration, meanwhile, a suspension mechanism serving as a vehicle is omitted, and the dead weight of the flying vehicle in the flying process is reduced. The vertical take-off and landing mode of overall tilting of the vehicle body omits a tilting mechanism of a vertical take-off and landing mode of tilting wings, and the dead weight of the flying vehicle during flying is reduced. A flow field during large-elevation-angle takeoff is effectively optimized through a boundary layer swallowing technology by means of a large-deflection wing trailing edge air suction seam, and the lift force of the large-deflection wing during large-elevation-angle takeoff is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of air traffic, in particular to an eVTOL flying car with wings retracted and suspended multiplexed. Background technique

[0002] In the context of global carbon peaking and carbon neutrality, hydrogen energy is the first choice for future aircraft, but there are deficiencies in hydrogen energy, such as low power density of hydrogen fuel cells, high requirements for hydrogen purity, and proton membrane technology mastered by Japan and the United States. At the same time, the energy efficiency of hydrogen fuel engines is lower than that of hydrogen fuel cells, and the conversion of electric energy requires an increase in the weight of generators.

[0003] eVTOL is of great significance to future transportation, but the design of hydrogen-powered eVTOL flying cars is particularly difficult. The main constraints are: (1) hydrogen power with higher power density is required for vertical take-off and landing; (2...
