简介：所谓的blisks，即不可分地bladed磁盘，被描绘由很低粘滞抑制的材料并且使flutter预言更批评。在那个框架，展示片和高eigenfrequency的复杂变丑的空间汽轮机blisk的二维的数字研究(>40kHz)被执行。模拟基于不稳定的雷纳兹平均Navier司烧在频率域线性化的计算并且在重叠在于一不稳定线性(及时)压力地，由泛音不安产生了，在之上一稳定非线性(在空间)流动。空气动力学的抑制系数在节的直径的一个范围上被计算，并且片被预言气动弹性变形地稳定。然而，强烈变化发生并且自从在稳定性的突然、大的偏差出现，是相当批评的。在那上下文，从串联宣传的波浪的性质被评估。如此的一条途径关于罐头也宣传到的不安提供基本知识远地(切上模式)或腐烂(截止模式)。流动的能力被不稳定的不安从串联被转移到的方法强烈影响抑制或放大片运动，这被期望远地。波浪的性质首先从上述的线性化的结果被估计，当时，他们是评估经分解并且最后比较。尽管有分析模型的强壮的假设，一个好协议被发现。结果显示出在cut-on/cut-off条件和稳定性之间的清楚的关联。最不稳定的配置在插头在入口和没有波浪对应于截止模式。没有从串联的出去的波浪，片是容易的不太稳定：从片颤动的体力必然被浪费或由串联发送了。
