| 摘 要： | 在对比化学点火、火药点火及电火花点火优缺点的基础上，选取了技术成熟、点火可靠的火药点火用于液氧／甲烷燃气发生器热试。用黑火药点燃固体推进剂的点火药量计算公式估算了火药点火药量，给出了液氧／甲烷燃气发生器火药点火器的其它参数。根据液氧／甲烷推进剂特点，确定了火药燃气-液氧-甲烷依次进入燃气发生器的点火时序。成功进行了4次液氧／甲烷燃气发生器热试，结果表明：液氧／甲烷燃气发生器点火起动过程平稳，点火品质较好，点火方案合理，适于较宽工作条件下的液氧／甲烷点火。

| Abstract: | The solid cartridge igniter was chosen for the ignition of LOX/methane gas generator in comparison with chemical and electric igniter.The parameters of the igniter were set by the calculation formula and experience of designing similar igniters.The time sequence of LOX/methane gas generator ignition was determined according to the characteristic of LOX/methane propellant.Four firing tests of LOX/methane gas generator were performed successfully.There was no sharp pressure peak or temperature peak appeared i... |
