Title:
MODULAR INTERMESHING AND TANDEM UNMANNED HELICOPTER AND WORKING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/259570
Kind Code:
A1
Abstract:
Disclosed in the present invention are a modular intermeshing and tandem unmanned helicopter and a working method thereof. The modular intermeshing and tandem unmanned helicopter is composed of two helicopter units which are connected together by means of a connecting device; the connecting device is a four-rotor connecting device or a tandem connecting device, the front and rear blades do not overlap with each other and have no height difference in a four-rotor mode, and the front and rear blades overlap with each other and have a height difference in a tandem mode. According to the present invention, a corresponding model can be selected according to task requirements; modularization is achieved and three modules can be freely switched; the advantages of a basic unit intermeshing helicopter such as good stability, compact structure, small pneumatic resistance, large lift force, good maneuverability for four rotors, and easy control and the advantages of a tandem helicopter such as strong crosswind resistance and large gravity center range are combined; a power system can be driven by electricity or petroleum. The present invention has a wide application prospect in the fields of electric power inspection, oil gas pipeline inspection, forest fire prevention, agricultural plant protection, public safety, transport loading and the like.
