| 摘要: |
| 常温推进剂液体火箭在炎热季节加注后往往容易产生结露现象，结露后形成的积水严重影响舱内仪器设备及电缆的使用安全。给出防结露吹除用量精确计算方法，通过对吹除入口压力、舱内达到压力、入口及出口面积等方面影响因素进行分析，得出吹除用量与上述因素的关联关系，提出火箭吹除量化控制措施，达到了稳定的控制效果。 |

| Abstract: |
| The problem of anti-condensation, which is caused by the propellant temperature of the rocket being lower than that of ambient atmosphere in hot seasons, is now considered to be an essential challenge to protect electronic equipment and cable. This paper focused on the accurate algorithm of air consumption for anti-condensation by analyzing the effect of blowout inlet pressure, equipment cabin environment pressure, blowout inlet and outlet areas. And the association relationship between air consumption and all factors was gained. An algorithm of air consumption quantification model has been found for seting up the anti-condensation system of rocket precisely. |
