MAIN LINE PASSENGER PLANE USING CRYOGENIC FUEL Russian patent published in 2017 - IPC B64D37/30 B64D37/04 B64D27/20 B64D11/00 B64C3/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to aeronautical engineering. The mainline passenger plane using the cryogenic fuel consists of the fuselage, swept wings of high aspect ratio, tail, engines installed on the fuselage. The fuselage has two parallel passenger cabins, between which a compartment for the cryogenic fuel tank. The height of the tank in cross-section, formed by the circles with ridges, is equal to the height of the passenger cabins cross section. In front of the fuselage the crew cabin and the passenger cabin of the first class are placed. Low-wing centre section, equipped with mechanization, is being placed under the floor of the passenger cabin and boiler compartment. At the bottom of the fuselage outside the wing centre section compartments for cargo containers are placed. Turbofan engines are placed on the top surface of the fuselage rear part with the possibility of the boundary layer of the fuselage into the bypass engines low-pressure side selection. Cryogenic fuel tank in the longitudinal direction is divided into two containers.

EFFECT: invention is aimed at improving the passenger aircraft performance characteristics.
