The present invention provides a device for test loading a fuselage barrel, in particular in the aviation and aerospace industry. The device comprises a first and a second pressure bulkhead for sealing the fuselage barrel at the end faces thereof in a pressure-tight manner. The device further comprises a support device which may be coupled to the first pressure bulkhead, on the one hand, and to the second pressure bulkhead, on the other hand, extending through the fuselage barrel. Moreover, the device comprises a loading device which may be coupled to the support device, on the one hand, and to a portion of the fuselage barrel, on the other hand, for introducing loads into the fuselage barrel. The resulting advantage is that gravitational force and/or acceleration forces acting on the masses arranged in the fuselage barrel, for example cargo, in particular during the flight phase may be simulated by means of components which are exclusively arranged within the fuselage barrel, which is pressurised during the test. Thus a provision of through-holes in the fuselage skin for passing through hydraulic cylinders and the sealing of said holes relative to the fuselage skin, as in the device known to the applicant, are avoided.
