Fuselage of an aircraft or spacecraft and method of activelyinsulating such a fuselage

Abstract

The present invention relates to a fuselage (1) of an aircraft or spacecraft, with at least one shell element (2) and a structural element (7). An interspace (5; 9) to which air can be admitted by an air stream (10) is provided between the at least one shell element (2) and the structural element (7). The fuselage is distinguished by the fact that, to form the air-admitting air stream (10) as an outgoing / incoming air stream of a pressurized interior space (20) of the fuselage (1), the interspace (5; 9) is connected to a corresponding outgoing / incoming air connection of the interior space (20). The invention also relates to a corresponding aircraft or spacecraft and to a method of actively insulating such a fuselage (1).

Description

Technical field [0001] The invention relates to a cabin of an aircraft or a spacecraft, an aircraft or a spacecraft with the cabin, and a method for actively isolating the cabin. Background technique [0002] Such a cabin is made of multiple parts. An aircraft or spacecraft, such as an airplane, is not only susceptible to huge load changes and stresses, but also susceptible to considerable temperature differences. For example, at a specific cruising altitude, the external temperature outside the cabin is approximately -55°C, while the internal temperature in the pressurized cabin area remains at a value of approximately +20°C. This is achieved by the air conditioning system. In the case of a traditional aircraft cabin, a heat insulation layer is provided inside the cabin, and the heat insulation layer also forms a sound insulation layer. [0003] The cabin may be in the form of a single-layer shell or a multi-layer shell, especially a double-layer shell. [0004] Figure 7 It show...
