Description

Technical Field

[0001] The utility model relates to the technical field of air-ground communication, and in particular to an air-ground communication device for eVTOL. Background Art

[0002] In terms of communication equipment, eVTOL (Electric Vertical Takeoff and Landing) electric vertical takeoff and landing aircraft usually require a reliable air-ground communication system to ensure flight control, data transmission and safe operation.

[0003] In the prior art, electric vertical take-off and landing aircraft usually install air-to-ground communication devices inside the fuselage. Air-to-ground communication devices installed inside the fuselage may be interfered with by signals from the aircraft's own electronic equipment. The internal space may cause the air-to-ground communication devices to overheat and make maintenance difficult. Air-to-ground communication devices installed inside the fuselage are not easy to access and maintain directly. Once a failure occurs, it may be necessary to disassemble part of the aircraft structure for repair, which prolongs maintenance time and cost. Therefore, an air-to-ground communication device for eVTOL is proposed to solve the above problems. Utility Model Content
