Rollover prevention airframe steel framework structure

The invention relates to a rollover prevention airframe steel framework structure, which belongs to the technical field of aircraft structure design. The rollover prevention airframe steel framework structure comprises a steel framework fuel tank area, a steel framework work bin area and a steel framework cockpit area, wherein the two sides of a fuel tank are fixed on first steel pipes on the two sides of the airframe steel framework through standard wrapping tapes, the bottom of the fuel tank is fixed on groove type parts at the bottom part of the airframe steel framework through standard wrapping tapes, the front end of the steel framework fuel tank area forms triangular structures III with the steel framework by a second steel pipe, the rear end of the steel framework fuel tank area forms triangular structures I with the steel framework by third steel pipes, and the steel framework work bin area and the steel framework cockpit area form triangular structures II with a center wing back beam and the steel framework by fourth steel pipes. The rollover prevention airframe steel framework structure is suitable for low-speed aircrafts, such as general-purpose aircrafts and agriculture and forestry aircrafts, and has the advantages of simple structure, high safety performance and low manufacturing cost.
