The invention discloses a
metal-fused high-bearing-capacity aircraft control surface, belongs to the technical field of aircraft control surfaces, and solves the problem that an existing
metal aircraft control surface is prone to high-temperature oxidation and
thermal fatigue. The rudderpost specifically comprises a
metal rudderpost body, a metal
flange assembly is connected to the metal rudderpost body, and the metal
flange assembly is wrapped with a composite shaft box
assembly. According to the invention, the fusion design of the metal
flange assembly and the composite shaft box assembly is adopted, the performance advantages of the two materials are brought into full play, the
bearing capacity of the control surface of the aircraft is remarkably improved, and the load demand under extreme conditions is effectively met; meanwhile, lightweight design is adopted while the
bearing capacity of the aircraft control surface is guaranteed, and the overall weight of the aircraft control surface is effectively reduced; in addition, the composite shaft box assembly can protect the metal flange assembly through the high
temperature resistance and the
oxidation resistance of the composite shaft box assembly, and the problems of high-temperature oxidation,
thermal fatigue and the like of the metal flange assembly are effectively restrained.
