Spiral multi-channel pulse detonation engine

The invention discloses a spiral multi-channel pulse detonation engine which comprises an engine shell, spiral partition plates, gas inlet slots, a plurality of spark plugs and a gas inlet rotor. The engine shell is circular, the spiral partition plates are fixed onto an inner ring wall of an annular cavity to form spiral channels, and the gas inlet slots are formed in the inner ring wall and are positioned among the spiral partition plates; two spiral slots which are in identical shapes are formed in the gas inlet rotor and are used as common gas inlet channels. The gas inlet rotor is in close fit with an inner ring of the engine shell and can freely rotate. The multiple spark plugs are mounted at the ends of the engine, are correspondingly matched with the spiral channels on the inner ring wall and are controlled by a computer, an automatic ignition effect can be realized according to the rotational speed of the gas inlet rotor and phase of the gas inlet channels, and accordingly a multi-tube time-sharing initiation effect can be realized. The spiral multi-channel pulse detonation engine has the advantages that a low-energy ignition mode is adopted by the engine, so that axial DDT (deflagration to detonation transition) distances can be shortened, and the spatial size of the engine can be effectively utilized; the gas inlet slots are formed in positions along a detonation chamber, and gas can flow into the spiral multi-channel pulse detonation engine via the gas inlet slots, so that the spiral multi-channel pulse detonation engine is short in filling time and high in gas inlet filling speed, and the detonation frequency can be increased.

High-frequency conical spiral tube type pulse detonation engine

The invention discloses a high-frequency conical spiral tube type pulse detonation engine. A multiple-tube coaxial stacking type inverted frustum-shaped structure is adopted, and is embedded in a conical ring-shaped passage between an outer casing and an inner casing of the engine, and the conical ring-shaped passage is positioned between an oxidizer storage cavity and an isolation gas storage cavity. During work, the gas in the cavities at the two sides can be preheated by the high temperature of gas in a conical spiral detonation tube, meanwhile, the conical spiral detonation tube is cooled by the gas in the cavities to avoid burnout of the detonation tube, and the heat cycle efficiency of the engine is improved by a heat return principle. The conical spiral detonation tube is provided with a reinforcing section, the filling time of combustible mixing gas is very short, the DDT (deflagration to detonation transition) distance and time can be obviously shortened, and the working efficiency of the engine is improved. The periodic thrust is generated by the high-speed spraying of high-temperature and high-pressure gas generated by pulse detonation waves. The high-frequency conical spiral tube type pulse detonation engine has the advantages that the structure is simple, the boosting components and rotary components are saved, the size is small, and the processing is convenient.

Composite pipe hydraulic expansion method, manufacturing device and obtained composite pipe

The invention provides a composite pipe hydraulic expansion method, which comprises the following steps that (1) a plug provided with a sealing ring in the circumferential direction is inserted into an inner pipe; (2) sealing pressure liquid is introduced to a position between the plug and an inner ring of the sealing ring for sealing the end part of the inner pipe; (3) the expansion is carried out, before the expansion, a sleeve ring with the same inner diameter as an outer pipe of a composite pipe is arranged in a way of tightly pasting the end surface of the outer pipe of the composite pipe requiring the expansion, and in addition, the innermost end of the sealing ring is arranged outside the end surface of the outer pipe of the composite pipe. The sealing position exceeds the end surface of the outer pipe, so the pressure inside an inner pipe cavity can reach the end part of the outer pipe, and the combining quality is ensured. The defect of composite blind region reservation at the end part of the composite pipe manufactured in the prior art is overcome, and the composite pipe can be used without cutting off the blind region, so the cost is reduced in aspects of both materials and the process. The cutting is not needed, so great convenience is brought for the subsequent processing of external screw threads formed at the pip end of the composite pipe before the expansion.

Liquid hydrogen vaporization and self-pressurizing device

The invention relates to a liquid hydrogen vaporization device, and specifically relates to a liquid hydrogen vaporization and self-pressurizing device. The liquid hydrogen vaporization and self-pressurizing device is used in the process of vaporizing liquid hydrogen into gasified hydrogen through an evapourizer and increasing the pressure of the hydrogen to form high-pressure hydrogen. When applied to the hydrogen energy field, the liquid hydrogen vaporization and self-pressurizing device can be specifically applied in hydrogen refueling stations adopting vaporization and pressure increasingof transported liquid hydrogen. When the high-pressure liquid hydrogen vaporization device is used for vaporizing the liquid hydrogen and achieving self-pressurizing, the pressure ranges from 10MPa to200MPa, a hydrogen compressor is not needed, and energy consumption is reduced. The invention further relates to three ways of filling the liquid hydrogen into the high-pressure liquid hydrogen vaporization device. In the two ways, pressure difference squeezing is adopted, and the liquid hydrogen in a high-pressure liquid hydrogen storage tank is conveyed into the high-pressure liquid hydrogen vaporization device; in the other way, the liquid hydrogen is conveyed to the high-pressure liquid hydrogen vaporization device through a liquid hydrogen high pressure pump. Cold energy of the liquid hydrogen is fully utilized by the liquid hydrogen vaporization and self-pressurizing device. Compared with prior equipment, the liquid hydrogen vaporization and self-pressurizing device can work withoutthe hydrogen compressor in the liquid hydrogen vaporizing and self-pressurizing process, and energy consumption is reduced obviously.
