A fuselage structure of an unmanned helicopter is provided. The fuselage
structure
relates to the field of unmanned helicopter design. The fuselage structure
comprises two side
frames and a rotor wing frame mounted between the two side frames. The
fuselage structure
is shaped like a trapezoid structure and is strengthened by a stiffening beam.
The fuselage
structure may be characterized by high strength, simple structure, few
components, and quick
disassembly for maintenance. I-section steel may be used for manufacturing
beam structures.
In addition, both the size and the weight of the fuselage structure are
reduced, thus reducing
the weight of the unmanned helicopter and improving the loiter time and
running efficiency of
the unmanned helicopter. Parts of the unmanned helicopter may be mounted on an
extension
beam.
Une structure de fuselage dun hélicoptère sans pilote est présentée. La structure de fuselage est liée au domaine de la conception dhélicoptère sans pilote. La structure de fuselage comprend deux cadres latéraux et un cadre de pale de rotor installé entre les deux cadres latéraux. La structure de fuselage est de forme semblable à une structure trapézoïdale et est renforcée par une barre de raidissement. La structure de fuselage peut être caractérisée par une structure simple très solide, le petit nombre de composantes et le démontage rapide en vue de lentretien. De lacier à section en I peut être utilisé pour la fabrication des structures de montant. De plus, la taille et le poids de la structure du fuselage sont réduits, diminuant ainsi le poids de lhélicoptère sans pilote et améliorant le temps du vol d'attente et lefficacité fonctionnelle de lhélicoptère sans pilote. Les pièces de lhélicoptère sans pilote peuvent être installées sur un montant dextension.
