飞机发动机产生的明冰会改变流场分布,影响发动机组的正常工作,同时脱落后的明冰可能会对发动机部件产生破坏。弯曲强度和压缩强度是明冰基本的力学性质,依据明冰的形成原理,人工喷制明冰,并对明冰的弯曲强度和压缩强度进行测试,分析了温度对弯曲强度和压缩强度的影响。该研究为准确判断冰脱落形式以及脱落后的运行轨迹提供了重要依据,同时也为冰脱落数值仿真计算提供了可靠参数。 The ice produced by the aircraft engines changes the flow field distribution and affects the normal operation of the engine block. At the same time, the fallen ice may cause damage to the engine components. The bending strength and compressive strength are the basic mechanical properties of the ice. According to the formation principle of the ice, artificial ice is sprayed and the bending strength and compressive strength of the ice are tested. The effect of temperature on the flexural strength and compressive strength . The study provides an important basis for accurately judging the form of ice shedding and the running trajectory after shedding, and also provides reliable parameters for numerical simulation of ice shedding.
