Embodiment Construction

[0042] exist figure 1 Middle: When the ship is moving forward, the control valve (3) of the high-pressure gas storage tank is opened, and the internal combustion engine (1) drives the air compressor (2) to press the gas into the high-pressure gas storage tank (6). The water valve (10) is opened, the exhaust valve (5) and the water inlet and outlet valve (11) are closed; the high-pressure gas in the high-pressure gas storage tank (6) enters the propulsion airbag (8) in the draft tube (9), The propulsion airbag (8) inflates rapidly, squeezes out the water from the right side of the guide tube (9), and pushes the hull forward; after the propulsion airbag (8) inflates to a certain extent, the air intake valve (7), water inlet and outlet valve (10) close, the exhaust valve (5) and the water inlet and outlet valve (11) are opened, the push air bag (8) is connected with the low-pressure air storage tank (4), and the water flows in from the left side of the guide tube (9), which will ...

Abstract

The invention relates to a high-efficiency silencing water surface or underwater driving technology. An air compressor / high pressure steam generator generates high pressure gas / steam, the gas outlet of the air compressor or high pressure steam generator is connected with a high pressure gas holder in parallel, the gas inlet of the air compressor or high pressure steam generator is connected with a low pressure gas holder / condenser in parallel, the high pressure gas holder is respectively connected with a boosting gas bag and an additional water ramjet subsystem, the low pressure gas holder / condenser is connected with the boosting gas bag, and the boosting gas bag is arranged in a guide pipe. The communication between a plurality of boosting gas bags and the high pressure gas holders or the low pressure gas holder / condenser is controlled to control expansion and contraction of the gas bags, the boosting gas bag is expanded to extrude the water in the guide pipe out, so as to generate athrust and drive a ship to move; the boosting gas bag contracts and the guide pipe is filled with water to be ready for jet flow at the next time; the direction of inlet outlet water in the guide pipe can be determined by controlling the open and close of water inlet outlet valves at the two ends of the guide pipe; and the process can be repeated to drive the ship to do various movements.

Description

technical field [0001] The patent of the present invention relates to a high-efficiency, quiet water surface or underwater drive technology, which can be used for the drive technology of various water surface or underwater moving objects or tools such as ships, ships, submarines or torpedoes. Background technique [0002] At present, the ship propulsion technologies that have entered the application stage are mainly water jet propulsion, propeller propulsion, positive displacement hydraulic pump water jet propulsion, etc. The main disadvantage of propeller propulsion is that the efficiency is not high, high-speed rotation produces cavitation, causing noise and vibration, and it will collapse when the power density is greater than 1.8MW / m*m. In addition, the ship needs to make a large turn when returning to the voyage, and the propeller is easy. Entangled in seaweed, fishing nets, etc. The efficiency of water jet propulsion is higher than that of propeller in the high-speed ...
