Abstract
A device that alters the breather hole configuration currently being employed in aircraft window assemblies. The device provides a means to allow slow moving air to pass and breathe through the breather hole, while stopping or significantly blocking non-steady air pulses from passing through. The device uses a combination of the cross-section and length of the air path that determines the effectiveness of the particular device to dampen out any unsteady airflow pulses.
Claims20
A device for dampening airflow through a breather hole in an aircraft window assembly, comprising:
- a damping device;
- and
- an airflow path defined within said damping device, said airflow path configured to dampen out non-steady air of a particular frequency and magnitude of incoming airflow while allowing slow moving air to pass.
An aircraft window assembly, comprising:
- a first window pane and a second window pane;
- a breather hole defined at a specified location through said first window pane;
- and
- a damping device positioned adjacent to said breather hole, said damping device defining an airflow path configured to dampen out a particular frequency range and magnitude of incoming airflow.
A window assembly comprising:
- at least one window pane including a breather hole capable of receiving incoming airflow;
- and
- means for dampening a particular frequency and magnitude of incoming airflow.
