摘要/Abstract

摘要： 为分析结构尺寸对端羟基聚醚推进剂发动机慢速烤燃响应特性的影响，开展了仿真计算研究。模拟不同直径和长径比发动机在慢速烤燃条件下的响应过程，分析慢速烤燃过程中推进剂的温度分布，以及反应温度、反应时间和反应位置随发动机直径和长径比的变化规律。建立一种基于图像处理的高温推进剂质量分布计算方法，计算慢速烤燃条件下发动机反应前推进剂的温度分布，并将其作为评价发动机慢速烤燃反应剧烈程度的参量。研究发现：直径大小对慢速烤燃响应时间和响应温度影响较大，长度影响较小；二者对反应位置影响都较大，随着尺寸和长径比的增大，反应位置向装药边缘移动，当尺寸较大时反应位置与壳体边缘的距离保持稳定；高温推进剂的质量占比随着长径比改变而发生变化，在装药量分别为5.5 kg、18.0 kg及44.0 kg烤燃件中，当装药直径在150~160 mm时，3种烤燃件发生反应前的高温推进剂占比最小。

Abstract: The response processes of hydroxyl terminated polyether (HTPE) propellant engines with different sizes and length-to-diameter ratios were simulated to analyze the effect of structure size on their slow cook-off response characteristics. The temperature distribution, reaction temperature, reaction time and reaction location of propellant were studied. A calculation method based on image processing is established to calculate the temperature distribution of propellant before reaction of motor under slow cook-off. The temperature distribution is used as a parameter to evaluate the response intensity of slow cook-off. The results show that the engine diameter has a great influence on the reaction time and temperature of slow cook off, while the engine length has little effect on them. Both of them have great influence on the reaction position. With the increase in the size and length-to-diameter ratio, the reaction position moves to the edge of the charge. When the size is large enough, the distance between the reaction position and the shell edge remains stable. The mass ratio of high temperature propellant changes with the change of length-to-diameter ratio. When the charge diameter is 150-160 mm, the proportion of high temperature propellant before reaction is the smallest with charges of 5.5 kg, 18.0 kg and 44.0 kg, respectively.
