Abstract

The invention relates to a heligyro and further relates to a bridge-type fuselage structure for a turbine wheel shaft unmanned helicopter. The bridge-type fuselage structure for a turbine wheel shaft unmanned helicopter contains a top plate 101, a middle plate 102, a lower plate 103, a forehand plate 201, a fuselage bulkhead 301, a back end plate 202, an engine installation bulkhead 302, a first tail tube installation bulkhead 401, a second tail tube installation bulkhead 402, a third tail tube installation bulkhead 403 and two side plates 601. The invention has large structural strength and light weight. 90% strength of the unmanned plane is loaded. In comparison with a traditional side plate structure, the structure provided by the invention has reduced weight by 30%. Airborne period and work efficiency of the unmanned plane are effectively improved.

Description

Technical field: [0001] The invention relates to a rotor helicopter, and further relates to a bridge-type fuselage structure of a turboshaft unmanned helicopter. Background technique: [0002] as attached Figure 4 As shown, the fuselage structure of the unmanned helicopter in the prior art is improved on the basis of the remote control model, and follows the design method of this side plate force. This structure results in relatively narrow space and low fuselage strength, which cannot provide good protection for airborne equipment. Room for improvement. Invention content: [0003] The object of the present invention is to provide a fuselage structure that improves the idle time and work efficiency of the unmanned helicopter and protects its control system. [0004] Turboshaft unmanned helicopter bridge fuselage structure, including: [0005] Distributed in order from top to bottom, and all are horizontally placed upper plate 101, middle plate 102 and lower plate 103; ...
