SEMI-RIGID AIRSHIP Russian patent published in 2024 - IPC B64B1/00 

FIELD: airship construction.

SUBSTANCE: invention can be used, in particular, for air transportation of large cargo to remote areas of the country. The airship includes a frame of two longitudinal beams located at a distance from each other. The beams are connected to each other by straps and covered on the outside with airtight fabric. The body consists of two cigar-shaped shells, inserted into one another with a gap. The outer one is made of airtight fabric, and the inner one is made of helium-proof fabric. The lower parts of both shells are attached to the frame beams along their entire length. The inner shell is additionally attached with tapes to the outer shell, and on the inside, it is divided into sections by vertical diaphragms. The crew nacelle is mounted on flexible connections between the longitudinal beams. The power plant is located on both sides of the nacelle. The engines have a liquid cooling system and propellers. Fuel tanks and ballast tanks are located between the longitudinal beams, and the chassis of 4 rotating struts with wheels is installed under the nacelle. The air bleed valve is located in the side part of the outer shell, and the excess pressure maintenance unit is located in the lower part of the outer shell of the airship. Helium safety valves are located on the side of the inner shell in each section. The nasal reinforcement frame is attached to the outer shell. The mooring device is located in the centre of the bow reinforcement coaxially with the longitudinal axis of the airship. Stabilizers with elevators are installed in the aft part of the airship, and the lower fin with rudder is located vertically below on the aft part of the airship hull and has a built-in control fan.

EFFECT: improved design.
