Problems solved by technology

For example, the cormorant submarine-launched UAV developed by the United States is currently the most reported similar technical solution. This aircraft adopts catapult launch, vertical take-off, and foldable wings. It can only exit the water once and is recovered by parachute. , also does not have the function of underwater or surface navigation

Embodiment 1

[0030] Such as figure 1 and figure 2 As shown, the overall layout of the aircraft is a nearly cylindrical fuselage 1 that is streamlined as a whole, wings 2 that are folded backwards and inwards on the outside, horizontal tails 3 and vertical tails 4 that play a controlling role, underwater propellers 5, and vertical lifters. Descending device 6 and front rotor 7.

[0031] The entire fuselage is divided into the front section of the fuselage and the rear section of the fuselage. The entire fuselage is linear. The front section of the fuselage is a streamlined design suitable for water flow and air flow. It includes an instrument cabin and a watertight compartment. The instrument cabin isolated from water is used for installation. Onboard electronic equipment such as power supply, communication, and sensors, and watertight compartments can absorb water or drain water to complete the operation of diving and surfacing the whole machine. The rear part of the fuselage is a long ...

Abstract

The invention discloses a general-purpose submersible aircraft layout, which includes a fuselage, the fuselage includes a front section of the fuselage and a rear section of the fuselage, and a folded fixed wing is arranged symmetrically on both sides of the front end of the fuselage. The folding fixed wing is provided with a vertical lifting device, the front part of the fuselage is provided with a rotor for parallel propulsion, the rear end of the fuselage is provided with a horizontal tail and a vertical tail, and the fuselage is provided with a vertical tail for floating in water. and submerged watertight compartments. The watertight compartment at the lower part of the engine room of the present invention is conducive to realizing the functions of repeatable diving and floating; the large dihedral angle of the wing can make the propeller of the vertical take-off and landing device break away from the water surface before starting, and at the same time provide rolling stability, which is both It can take into account high and low speed flight in the air, reduce the impact load of entering the water and the resistance of underwater navigation, and increase the speed of exiting the water to complete the conversion of various motion states.

Description

technical field [0001] The invention relates to the field of trans-medium aircraft, in particular to a general-purpose submarine aircraft layout. Background technique [0002] Submersible general-purpose aircraft (flying submersible) refers to a new type of equipment that can meet the needs of air, underwater and surface flight or navigation at the same time. It has the characteristics of fast maneuverability of aircraft and high concealment of submarines. Military applications are of great significance. The layout design of the submersible general-purpose aircraft is very important, and it is required to have good underwater performance and air performance at the same time. This requirement is a new problem that needs to be solved in fluid mechanics. The density difference between water and air is 800 times, the viscosity coefficient is about 100 times different, the Reynolds number is an order of magnitude different, and the buoyancy is 800 times different. The difference...
