Anti-rollover airplane fuselage steel framework structure

The utility model relates to an anti-rollover airplane fuselage steel framework structure, and belongs to the technical field of airplane structure design. The anti-rollover airplane fuselage steel framework structure comprises a steel framework oil tank area, a steel framework feed box area and a steel framework cockpit area, wherein two sides of an oil tank are fixed on first steel tubes on two sides of a fuselage steel framework through standard tapes, and the bottom of the oil tank is fixed on trough type parts at the bottom of the fuselage steel framework through standard tapes; the front end of the steel framework oil tank area and the steel framework form triangular structures III through a second steel tube; the rear end of the steel framework oil tank area and the steel framework form triangular structures I through third steel tubes; the steel framework feed box area, the steel framework cockpit area, a central wing rear beam and the steel framework form triangular structures II through fourth steel tubes. The anti-rollover airplane fuselage steel framework structure is applicable to low-speed airplanes such as a general-purpose plane, an agricultural aircraft and the like and has the advantages of simple structure, high safety performance and low manufacturing cost.
