Problems solved by technology

[0010] 2.5.1 The structure is quite complicated. In a gear pump, there are 6 sub-pumps to form a planetary gear train
Although the pump I innovated can also be made into a hovercraft pump, but because the power consumed by the hovercraft is too large, it is not cost-effective in terms of shipping costs, so the air cushion is not used

Embodiment Construction

[0029] 5.1 Assume referring to the data of a certain nuclear submarine, it is changed to a conventional powered diving aircraft carrier, with a displacement of 5,500 tons, a total length of 106 meters, a body width of 10 meters, an underwater speed of 25 knots, a total shaft power of 15,000 horsepower, and a single aircraft of 7,500 horsepower.

[0030] 5.2 Seek propulsion. Diving sailing will overcome water resistance, according to Newton's third law F=75N / V, wherein N=7500HP, substituting, two pumps can provide 2F=75*7500 / 12.85*2=87548kgf=87.55 tons of force. Thrust-to-weight ratio i=87.55 / 5500=1 / 62.82 for diving and sailing. When fighter jets are cruising, i=1 / 4. It can be seen that the thrust-to-weight ratio of water navigation is much smaller than that of airplanes. After all, the two speeds are different.

[0031] 5.4 Provide N=7500HP according to each pump, the total efficiency of the pump is set to η=0.83, and the pressure P=100kgf / cm 2 Choose a secondary pump, and t...

Abstract

The invention discloses a pump water spray propulsion double-hydrofoil shallow diving carrier, which is technically characterized by absorbing the superiorities of a submarine, a carrier, a modern small water plane catamaran with superhigh speed and a hovercraft, and by using 'a multilevel double-circular-arc-gear high pressure pump with large flow rate', 'a multilevel internal series double supercharged and double-circular-arc-gear pump' as a water spraying pump and an air-cushion pump of a ship and by adopting the structure of a shallow diving carrier which uses a multi-functional double hydrofoils submerged body to provide buoyancy and dynamic forces. The ship body carries power and pump spraying water, which transports the high pressure and large flow rate water to a direction-adjustable spray head which is positioned on the tail part of the multi-functional double hydrofoils submerged body under the ship body, so as to achieve the water spray propulsion. Besides providing the buoyancy and dynamic forces, the double hydrofoils submerged body also has the functions of oil storage, inputting water in a respective cavity and controlling the shallow diving and the ship attitude, and is also provided with overall strength, thus forming a small water plane catamaran structure; the double hydrofoils submerged body is also provided with an air-cushion. When the submerged body uses the pump to exhaust water, the ship body surfaces, and likes a small water plane catamaran, the spray head can spray water and is promoted in water when avoiding the water resistance to go forward at high speed; the carrier is a propeller-typed ship and can not realize a sea skimming flight, which is the most superiority in the water spray propulsion.

Description

1. Technical field: [0001] The present invention relates to providing a structure of shallow submersible aircraft carrier with "multi-stage double circular gear high-pressure large-flow pump" as the propulsion power for water jetting and multifunctional double-hydrofoil submerged body providing buoyancy and dynamic lift, especially suitable for conventional Powered light aircraft carrier and equipped with a modified "pump jet propulsion fixed-wing helicopter." 2. Background technology [0002] 2.1 Germany, Japan, Britain, the United States, France and other countries have all built diving aircraft carriers. As early as December 1941, after Pearl Harbor was bombed, several Japanese planes appeared out of nowhere. In less than a year, several Japanese planes from unknown origins also appeared in Arizona, USA, and disappeared without a trace after a whirlwind bombardment. It turned out that these planes all took off from Japanese diving aircraft carriers. [0003] At present...
