Abstract

The invention discloses an oxygen / kerosene ignitor using a pneumatic resonance ignition technology, and belongs to the field of rocket motors. The oxygen / kerosene ignitor using the pneumatic resonance ignition technology comprises an oxygen path nozzle (1), a sealing spacer (2), a hot surface ignitor (3), a positioning ferrule (4), a sealing spacer (5), a resonating tube sleeve (6), a sealing spacer (7), a main oxygen collection ring (8), an ignitor body (9), an ignitor head (10), a kerosene / oxygen combined nozzle (11), a sealing spacer (12), a cavitation pipe (13), a kerosene connecting nozzle (14) and a sealing spacer (15). The hot surface ignitor works by using a pneumatic resonance heating method; and the resonating pipe is positioned on the side face of the ignitor head. The kerosene is sprayed into the nozzle from the side face of the kerosene / oxygen combined nozzle in the radial direction. The oxygen axially passes through the combined nozzle. The ignitor body is positioned in the main oxygen collection ring for replenishing oxygen to a burning torch for burning.

Description

【Technical field】 [0001] The invention relates to a gas-oxygen kerosene igniter device using pneumatic resonance ignition technology. 【Background technique】 [0002] The commonly used ignition technology for liquid rocket engines using liquid oxygen and kerosene as propellants is to use starting fuel that can spontaneously ignite with gas and oxygen. The kerosene and liquid oxygen are ignited. This ignition technology is very reliable. It can be used for the aerodynamics of the first stage and the second stage rocket engine. Its main disadvantage is that it can only be started once and cannot meet the requirements of multiple starts. . At the same time, spontaneous combustion fuel is toxic, flammable, explosive, and difficult to store. For liquid oxygen and kerosene rocket engines, in order to start multiple times, a special starting system can also be designed. When starting, the main valve of the oxidant is opened, and the starting fuel supply valve of the starting nozz...
