Problems solved by technology

[0003] At present, carrier-based aircraft mainly adopt two methods of steam ejection and electromagnetic ejection. Among them, steam ejection needs to convert seawater into fresh water first, and then convert fresh water into high-pressure steam. In this process, energy consumption is large and the utilization rate is low. The volume of the device is huge, and the system structure is extremely complex. At present, only a few countries can master its core technology
Although electromagnetic ejection has the advantages of large thrust, low energy consumption, and high efficiency, it has irreparable shortcomings, that is, it will generate strong electromagnetic interference, which not only seriously affects the electromagnetic environment and working reliability of the electromechanical equipment on the aircraft carrier, but also is not conducive to the The maneuverability and stealth of the ship formation restrict its combat effectiveness to a certain extent
Therefore, how to develop a new type of carrier-based aircraft ejection device to overcome the shortcomings of steam ejection devices such as high energy consumption and complex systems, and to avoid problems such as strong electromagnetic interference generated by electromagnetic ejection devices, is of great importance to improving the take-off capability of carrier-based aircraft and The combat effectiveness of the aircraft carrier is of great significance

Abstract

The invention relates to a hydrodynamic force catapulting device of a carrier-borne aircraft and relates to the technical field of weapon launching. The medium state and energy conversion processes from seawater to fresh water and then from fresh water to high-pressure steam are not need for achieving the catapulting device, and a seawater medium in the ocean is directly used for transmitting energy and acting, so that the device is simple in structure, compact in size, low in energy consumption in the catapulting process and high in energy use rate. In addition, the catapulting device uses high-pressure seawater as catapulting power, no electromagnetic interference is generated, and invisibility of a naval ship and reliable and stable work of mechanical and electrical equipment on the naval ship are facilitated.

Description

technical field [0001] The invention relates to the technical field of weapon launching, in particular to a hydrodynamic ejection device for a carrier-based aircraft. Background technique [0002] Ejection devices (catapults) are widely used in the launching process of aircraft, especially for carrier-based aircraft based on aircraft carriers, the use of catapult devices can greatly shorten the running distance, increase the load and efficiency of take-off, and significantly improve the aircraft carrier. The maneuver reaction time and combat effectiveness of the carrier aircraft. [0003] At present, carrier-based aircraft mainly adopt two methods of steam ejection and electromagnetic ejection. Among them, steam ejection needs to convert seawater into fresh water first, and then convert fresh water into high-pressure steam. In this process, energy consumption is large and the utilization rate is low. The volume of the device is huge, and the system structure is extremely co...
