Abstract

The invention provides a multi-navigation-state in-water aircraft. The multi-navigation-state in-water aircraft comprises a main boat body, wherein a streamline superstructure is arranged on the main boat body; a lifting integrated mast is mounted in the superstructure; adjustable hydrofoils are symmetrically mounted on two sides of the front part of the superstructure; electric propulsion devices are symmetrically mounted on two sides of the rear part of the superstructure; an airtight driving control cabin, a fuel oil and battery cabin, a main engine cabin and a floating state adjusting cabin are arranged in the main boat body; a water inlet and a water outlet which communicate with each other are separately formed in the front part and the rear part of the main boat body; a cabin air inlet and a cabin air outlet which communicate with the main engine cabin are separately formed in the integrated mast; a surface propeller propelling device is arranged at the rear part of the main boat body; and the main boat body adopts a boat type of a single all-knuckle deep-V-shaped planing boat and the deadrise angle of a stern is 18 degrees. The multi-navigation-state underwater boat disclosed by the invention takes account of the high-speed performance of a water surface boat, the high seakeeping of a semi-submerged boat and the invisibility of a submerged boat; a large amount of water surface sensor equipment and a large amount of underwater sensor equipment can be picked up; and the multi-navigation-state in-water boat can be widely applied in the field of marine scientific research.

Description

technical field

[0001] The invention relates to an aircraft, in particular to an underwater aircraft with multiple navigation states. Background technique

[0002] The multi-navigation state underwater vehicle is a vehicle that can switch between low-speed underwater navigation, semi-submersible fast navigation and high-speed surface navigation through floating state adjustment and speed change. The battery-powered electric propulsion method is used for underwater navigation, and the diesel engine-powered surface paddle propulsion method is used for semi-submersible fast navigation and high-speed surface navigation. Only the integrated mast that doubles as the air vent of the main engine is exposed above the water surface during semi-submersible navigation. , when sailing at high speed, the main hull lifts off the water surface and enters the gliding state.

[0003] At this stage, conventional underwater vehicles are generally used in a single way. The speed of underwater v...

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] combine Figures 1 to 7 , the present invention is made up of main hull 4, superstructure 5, integrated mast 3; Inside the main hull 4, a driving control cabin 9, a fuel and battery cabin 10, a main engine cabin 11, and a floating state regulation cabin 12 are arranged; The adjustable hydrofoil 6 is installed symmetrically on the side, and the electric propulsion device 2 is installed symmetrically on both sides behind the superstructure 5; the integrated mast 3 is equipped with radar, photoelectric pod, GPS antenna, Beidou satellite communication system, radio antenna and other equipment. There is an opening on the mast that directly connects the main engine cabin and the exhaust pipe of the main engine, and the ventilation of the engine room is realized by the fan during water surface and semi-submerged navigation.
