中航工业飞机强度研究所顺利完成国内首次缩尺钛合金空心叶片冰撞击特性试验。该试验分为两个阶段:第一阶段开展刚性靶冰撞击试验,目的是评估不同制冰工艺对冰力学性能的影响,以获得一种较优的制冰工艺,并通过撞击试验数据校准冰的动力学分析模型。第二阶段是空心风扇叶片缩比试验件的冰撞击试验,目的是获得高速冰撞击条件下叶片的动态响应特
China Aviation Industry Aircraft Strength Institute successfully completed the first domestic ice sculpture of titanium alloy hollow blade impact characteristics test. The test is divided into two stages: the first stage of the rigid target ice impact test, the purpose is to assess the different ice making process on the mechanical properties of ice in order to obtain a better ice making process, and through the impact test data calibration ice Kinetic analysis model. The second stage is the impact test of the hollow fan blade shrinkage test piece, the purpose is to obtain the dynamic response of the blade under high-speed ice impact conditions
