    • The Aeroelastic Model using the Principal Shapes of modes (AMPS) is a method used to predict flutter in gas turbine engines. Modern gas turbine engines often include rotors with flexible disks and/or significant blade geometry variations. The AMPS method accounts for the varying blade mode shapes associated with flexible disks as well as changing blade geometry, providing accurate flutter predictions for a large number of modes from a relatively small number of CFD (computational fluid dynamics) simulations. The AMPS method includes determining a smaller set of principal shapes that approximates a larger set of structural modes of interest. Using linear superposition, aerodynamic forces associated with the vibration of the principal shapes can be used to construct the full aerodynamic coupling matrix associated with the structural modes of interest. An eigenvalue equation is solved to determine a damping distribution associated with the structural modes of interest. The damping distribution is predictive of flutter.
    • 使用模态主成像(AMPS)的气动弹性模型是用于预测燃气轮机发动机颤振的方法。 现代燃气涡轮发动机通常包括具有柔性盘和/或显着的叶片几何变化的转子。 AMPS方法考虑到与柔性磁盘相关联的变化的刀片模式形状以及改变刀片几何形状,从相对较少数量的CFD(计算流体动力学)模拟中为大量模式提供准确的颤动预测。 AMPS方法包括确定近似较大的一组感兴趣的结构模式的较小的主形状集合。 使用线性叠加,可以使用与主要形状的振动相关联的空气动力来构建与感兴趣的结构模式相关联的全部空气动力学耦合矩阵。 解决特征值方程以确定与感兴趣的结构模式相关联的阻尼分布。 阻尼分布可预测颤振。

    • Methods and systems for reroute and generation of backward routing information are provided. When an originator node wants to transmit a packet to a destination node and cannot transmit the packet to a next node recorded in a routing table, the originator node records a backward packet tag and information of the originator node into the packet, and transmits the edited packet to a backup node recorded in the routing table. The backup node retrieves a backward routing table in response to the backward packet tag to see whether a forwarding node corresponding to the originator node and the destination node is a backward routing terminal. If not, the backup node transmits the packet to the forwarding node. If so, the backup node removes the backward packet tag and the information of the originator node from the packet, and transmits the packet to the forwarding node.
