Embodiment Construction

[0023] As shown in the figure, hydrogen peroxide is decomposed by the catalytic bed to produce water vapor and oxygen. This high-temperature and high-pressure mixed gas is mixed with alcohol immediately after leaving the catalytic bed, and then enters the combustion chamber through the atomization of the nozzle. In the combustion chamber, the igniter is installed on the wall of the combustion chamber (the tip of the rectification plate must be located in the upstream area of ​​the flow field, so that it can decelerate better). A low-velocity zone is generated downstream of the plate. At this time, the electrode of the igniter excites a pulse voltage of 20kv to ignite the gas in the low-velocity zone. Since the electrode is located at the edge of the low-velocity zone, the ignited gas can quickly spread to the entire combustion chamber.

[0024] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited ...

Abstract

The invention discloses a novel igniter used for the combustion reaction of hydrogen peroxide and alcohol. Including rectifier plate, electrode, igniter body. The igniter body is cylindrical, with positioning pins and flanges; the rectifier plate is V-shaped, and is fixed to one end of the igniter with the electrodes, arranged radially. When in use, the igniter is installed in the combustion chamber. When the high-speed premixed gas passes through the rectifying plate, the speed decreases, and the ignition electrode starts to generate a pulse voltage of 20kv and 12Hz to ignite the premixed gas.

Description

technical field [0001] The invention relates to the technical field of aerospace engines, in particular to a power system for micro-nano satellites using 70% hydrogen peroxide and alcohol as raw materials. [0002] technical background [0003] With the development of high-tech and the promotion of demand, micro-nano satellites have the advantages of small size, low power consumption, short development cycle, formation and networking, and many complex space tasks at a lower cost. It plays an important role in commercial and other fields. [0004] Micro-nano satellite technology research and its networking application technology is one of the hotspots in international satellite technology research, which belongs to the category of high-tech exploration. Micro-nano satellites are mainly used in communications, military, geological exploration, environmental and disaster monitoring, transportation, meteorological services, scientific experiments, deep space exploration, etc. A...
