Dynamic resonance system and method for the anti-icing and de-icing of inlet grids

A system, comprising:

• an inlet grid configured to reduce distortion of an incoming airflow;
• a vibration device coupled to the inlet grid;
• a controller communicatively coupled to the vibration device, the controller configured to transmit a vibration signal to the vibration device;
• wherein the vibration signal is operable to cause the vibration device to vibrate the inlet grid such that the inlet grid resonates at a natural frequency, thereby inducing a mode shape in the inlet grid, the mode shape configured to break up and prevent ice on the inlet grid;
• and
• wherein:
• the vibration device is a first vibration device, the vibration signal is a first vibration signal, the natural frequency is a first natural frequency, and the mode shape is a first mode shape;
• and
• the system further comprises:
• a second vibration device coupled to the inlet grid;
• the controller is further configured to transmit a second vibration signal to the second vibration device;
• and
• the second vibration signal is operable to cause the second vibration device to vibrate the inlet grid such that the inlet grid resonates at a second natural frequency, thereby inducing a second mode shape, the second mode shape configured to break up and prevent ice on the inlet grid;
• and
• the first vibration device and the second vibration device operate concurrently;
• and
• the first mode shape and the second mode shape superimpose at one or more anti-nodes on the inlet grid.
