The invention discloses a rack assembly. The rack assembly comprises a front machine body rack assembly, a middle machine body rack assembly and a rear machine body rack assembly which are sequentially connected from front to back. The rack assembly further comprises a bottom frame assembly connected with the bottoms of the front machine body rack assembly, the middle machine body rack assembly and the rear machine body rack assembly, and the front machine body rack assembly, the rear machine body rack assembly and the chassis assembly are truss assemblies composed of a plurality of rod pieces. The rack assembly is reasonable in structural layout, small in dead weight, uniform in stress distribution and good in loading capacity, and the overall performance of the crossed double-rotor unmanned helicopter can be correspondingly improved. The invention further discloses the crossed double-rotor unmanned helicopter applying the rack assembly.
本发明公开了一种机架总成,包括自前至后顺次连接的前机身机架组件、中机身机架组件和后机身机架组件,还包括连接于所述前机身机架组件、所述中机身机架组件和所述后机身机架组件的底部的底架组件,所述前机身机架组件、所述后机身机架组件以及所述底架组件均为由若干杆件组成的桁架组件。该机架总成的结构布局较为合理,自重较小且应力分布均匀,载重能力较好,能够使交叉双旋翼无人直升机的整体性能得以相应提高。本发明还公开了一种应用上述机架总成的交叉双旋翼无人直升机。
