Embodiment Construction

[0017] Below, the present invention will be further described in conjunction with accompanying drawing and specific embodiment:

[0018] In the air cruising section, the working mode of solid rocket ramjet combined with powder fuel ramjet is adopted: the oxygen-enriched fuel with high metal content is burned in the gas generator 1 as an on-duty flame, and high-temperature fuel-rich gas is generated and enters the combustion chamber 11; at this time, the engine The motor 4 in the casing drives the baffle 3 to close, the motor 4 in the gas generator casing drives the baffle 3 to open, and the flow path is converted to the air inlet mode; at the same time, the fuel in the powder fuel storage tank 7 is pushed from the outlet through the piston 8 10 is ejected, mixed with incoming air and high-temperature fuel-rich gas in the combustion chamber, and further burned to produce high-temperature and high-pressure gas that expands through the tail nozzle 12 to perform work and generate t...

Abstract

The invention relates to a cross-media ramjet based on solid propulsion. The cross-media ramjet based on the solid propulsion is characterized in that a flow path in integrated design with a gas generator is evenly arranged on the outer circumference of the gas generator, thus ensuring not only the normal operation of the ramjet but also the streamline shape of the gas generator; flow path bafflesare driven by a baffle drive motor to control the closing and opening of upper and lower flow path baffles so that air inlet and water intake modes are switched. With a parallel flow path utilized torealize the integration of an air inlet and water intake of the cross-media ramjet, and the starting, shutdown and motion speed of a powder supply device controlled, the cross-media ramjet based on the solid propulsion has the advantages of achieving fuel delivery and stop and flow control, achieving controllable supply of powdered fuel well, and meeting gas flow requirements for different modesand thrust regulation.

Description

technical field [0001] The invention relates to the fields of powder fuel ramming, solid rocket ramming, water ramming and the like, in particular to a solid propulsion-based trans-medium power device. Background technique [0002] Trans-medium aircraft is a new concept aircraft that can fly in the air and submerge underwater. It has both the speed of the aircraft and the concealment of the submarine. It can fly over seas and carry out concealed and precise strikes. It can effectively use the blind spots of radar and various detection equipment to launch surprise attacks on enemy aircraft carriers, warships and submarines. It has efficient penetration strikes and multi-mission capabilities. As early as the 1920s and 1930s, someone proposed the idea of ​​a diving plane or a flying submarine, but limited to the technical level, it has not been successfully transformed into an engineering model so far. With the development of technology in recent years, especially the rapid de...
