  • 摘要:

    冲压空气涡轮(RAT)泵将涡轮输出的机械能转换为液压能用以操控飞机舵面,其快速起动是飞机安全的最后保证。长时间处于低温大气环境,液压油的高黏性阻碍了液压泵的快速起动,将飞机主液压系统的高压油液引入RAT泵是解决该问题的有效方法。本文以RAT泵为研究对象,探究RAT泵的最小温控节流孔计算方法。首先,阐述RAT泵待机状态下通过温控节流孔保温原理,提出温控节流孔的孔径计算方法;其次,建立RAT泵热力学模型,推导温控节流孔的孔径计算公式;然后,基于MATLAB平台搭建RAT泵温控系统热力学模型;最后,通过仿真计算,由仿真结果验证本文所提出的温控节流孔计算方法的正确性,且节能效果显著。
