液体火箭发动机

关键词

液体火箭发动机液体火箭常温燃料

准备制造一台250N级小推力液体火箭发动机

推进剂为NTO-UDMH

室压5MPa

组元混合比2.15

下图为燃烧室型面图

下图为总装图，燃烧室圆筒段采用浇铸酚醛树脂隔热，喷管使用石墨，喷注器，石墨固定件和外壳为304不锈钢

喷注器中间走的NTO，旁边3股为UDMH。

管路目前设计为这样，全部采用304不锈钢螺纹1分，2分，4分连接。

电磁阀一个为耐腐蚀款一个为普通电磁阀耐压10MPa。

防毒面具滤毒盒容易饱和，最好使用空气呼吸器作为呼吸防护，身体防护一般防化服即可。

洗消采用碳酸钠溶液加草酸溶液加自来水组合。
