The utility model relates to a non-rigid aerocraft charging wing, which comprises a framework, an envelope, and outer ribs used for connecting the body of the aerocraft; the outer ribs are fixed on the framework and the envelope is stuck on the framework. Compared with the prior art, the non-rigid aerocraft charging wing leads the hard framework and a charging cell body to be organically combined; after high pressure gas is charged in the charging cell body, not only the weight of the traditional wing of the aerocraft is greatly reduced, but also the wing can be maintained with an excellent appearance by sticking the framework and the envelope; if the gas with a density smaller than that of air is charged inside, an extra buoyancy can be provided, thus further lightening the weight of the wing, and even being capable of providing extra buoyancy to the aerocraft simultaneously when completely canceling the deadweight; moreover, the structure can bear larger load by relying on the high pressure air and the framework.
