Title:
入口グリッドの防氷及び除氷のための動的共振システム及び方法
Document Type and Number:
Japanese Patent JP6637856
Kind Code:
B2
Abstract:
In one embodiment, a system includes an inlet grid configured to reduce distortion of an incoming airflow. The system may also include a vibration device coupled to the inlet grid and a controller communicatively coupled to the vibration device. The controller may transmit a vibration signal to the vibration device causing the vibration device to vibrate the inlet grid such that the inlet grid resonates at a natural frequency inducing a mode shape in the inlet grid. The mode shape may break up and prevent ice on the inlet grid.
