AIRSHIP OF INTERCITY AIR TRANSPORTATION OF VARIOUS RANGES Russian patent published in 2023 - IPC B64B1/06 

FIELD: lighter-than-air aircrafts.

SUBSTANCE: scope of the invention is the air transport of local, interregional traffic. The airship contains compartments filled with light gas, with compressors for pumping gas from one compartment to another, wings, a compartment with the main engine thrust screw, piloting and steering devices for the airship, hulls for accommodating the payload and units for functioning of the airship working systems, the pilot's cabin. Moreover, the wings, separated by the engine compartment, are equipped with hinges for turning to the upper position, contain compartments filled with light gas and are designed in such a way that their total lifting force balances the mass of the aircraft without payload. Each wing in cross section is made in form of aerodynamic profiles with a smooth increase in the area of these sections towards the centre and is fastened with longitudinal and transverse sets of stringers. The central compartment with light gas is connected to the housings for placing the payload and the units for the functioning of the working systems of the airship. The engine is made with the possibility of turning the main screw in a vertical plane at an angle of up to 90°. The movable nose parts of the wings are interconnected by means of additional hinges, which are connected through slotted boxes to flat plates, to which the cockpit is attached in the centre. The drive of the main screw contains an electric motor connected via an electric line with two hydrogen fuel cells connected to two air preparation units and a hydrogen-containing component contained in two tanks. Pivot screws mounted at the ends of the wings are designed to balance the moment of the main rotor stator during all phases of flight.

EFFECT: reduction of take-off weight by reducing the volume of compartments with light gas, increase of the payload ratio, reduction of the area of the parking space and simplification of the procedure for parking the airship.
