INFLATABLE AMPHIBIOUS AIRBOAT Russian patent published in 2022 - IPC B60F3/00 B60V1/18 B63B1/32 

FIELD: vehicles.

SUBSTANCE: invention relates to vehicles, namely to water vessels adapted for movement on an air bag. An inflatable amphibious airboat includes an inflatable raft, which consists of main cylinders, forming sides and a bow of the airboat, additional cylinders placed between main cylinders along the airboat, lower and upper bottoms of the boat, forming a closed shell. In the lower bottom, holes are made for air release from a pumping engine from the mentioned shell under the airboat, as well as bottom protecting tapes. A pushing main engine is mounted on an airboat stern, a propeller of which is placed behind it with the possibility of rotation in a vertical plane and creation of a traction force pushing the airboat forward. A bulwark is mounted above main cylinders of the airboat. Additional cylinders are made glued between each other and to main cylinders, forming air caverns between the main bottom, main and additional cylinders. Air caverns are made plugged in a bow and stern parts of the airboat, using partitions glued between main, additional cylinders and the main bottom, and holes for air release from the mentioned caverns are made in the main bottom between main and additional cylinders and between additional cylinders. In the front half of the airboat, between the mentioned cylinders, nozzles are mounted for pumping air to caverns by the pumping engine mounted on a rigid deck of the airboat and communicated with nozzles by an air duct passing through a hole made in the upper second bottom and the airboat deck. The airboat deck is mounted on the second bottom on a crate consisting of longitudinal and transverse guides mounted to them.

EFFECT: improvement of hydrodynamic characteristics.
