| 摘要 |
The invention relates to an electrolytic igniter comprising an injector (2) forming a first electrode, a second electrode (5) which is electrically insulated from the injector (2) by an insulator (4) and extends downstream of the injector (2), a store (12) for the first monopropellant, an electrovalve (11) inserted between the store (12) and a distribution channel for distributing the first monopropellant into a device for injecting the first monopropellant, said device consisting of at least one injection hole (1) culminating in the vicinity of the second electrode (5), and a power supply circuit which is designed to take the second electrode (5) to a potential of between 50 and 1000 V in relation to the potential of the first electrode (2). The dissipation of the electrical power by ionic conduction in a free jet of the first monopropellant triggers the spontaneous decomposition of the first monopropellant and the production of the combustion gas (14) ensuring the ignition of jets of a second monopropellant from a main injector arranged in the vicinity of the second electrode (5). |
