Problems solved by technology
From the design ideas of Delft University and Boeing, it can be seen that whether it is figure 1 single-layer "bubble" fuselage or figure 2 The double-deck passenger cabin fuselage, the floors of the cylindrical fuselage of each layer are on the same level, which means that in order to meet the height requirements of the passenger and cargo compartments, the central fuselage needs to be modified, which will inevitably affect the aerodynamic characteristics

The invention provides a stepped BWB layout passenger and cargo cabin arrangement method. Different from the traditional passenger and cargo cabin arrangement, the passenger and cargo cabin floor in the invention is not on the same horizontal plane, but is distributed in a stepped shape according to different aerodynamic contour height of the section in which the passenger and cargo cabin are located. The goal of the staircase arrangement is to maximize the cruise lift-drag ratio by taking into account the supercritical airfoil shape of the central fuselage as much as possible under the constraints of the cabin and cargo space arrangement.
Description
technical field [0001] The invention belongs to the technical field of overall arrangement in passenger aircraft design, and in particular relates to a method for arranging a passenger cabin with a stepped BWB layout taking into account the aerodynamic shape. Background technique [0002] The basic principle of the traditional BWB layout cabin design is similar to the conventional layout. The passenger and cargo compartments are arranged in a way of multi-channel and multiple cylindrical fuselages side by side. This arrangement is also called "bubble" fuselage design. figure 1 The BWB layout aircraft designed for Delft University in the Netherlands uses this typical multi-cylindrical fuselage design. figure 2 It shows another design method of passenger and cargo compartments, that is, the double-deck passenger and cargo compartment design. The BWB layout in the prior art all adopts horizontal floors for the cabin layout, that is, the cabin floors are basically located on th...
