AIRCRAFT FUSELAGE WITH INTEGRATED POWER-ABSORBING STRAINING STRUCTURE AND AIRCRAFT WITH SUCH FUSELAGE Russian patent published in 2015 - IPC B64C1/06 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Fuselage (1) comprises ring-like frames (10, 110, 210), spars (12) to interconnected said frames and outer skin (14) that makes the fuselage lining (16, 116, 216). Fuselage (1) houses bottom floor structure (3, 103, 203) provided with several beams (32, 132, 232) connected with said frames (10, 110, 210), and floor lengthwise beams (4, 5, 30, 104, 105, 204, 205) for connected of the latter. Straining structure is made in fuselage lower area, under bottom floor structure (3, 103, 203). Said structure has first inelastic-straining mid area (20, 120, 220) and second L.H. or R.H. inelastic-straining area (26, 28; 126, 128, 226, 228). The latter features higher stiffness in vertical direction than said mid area. Claimed aircraft features above described fuselage.

EFFECT: higher efficiency of damping.
