Abstract
A system may include a first duct including an air inlet end and an air outlet end, and a valve within the first duct and configured to open to allow or close to prevent fan duct air from the air inlet end to pass through to the air outlet end of the first duct. The system may also include a second duct including a first end and a second end. The first end of the second duct may be coupled to a sidewall of the first duct and configured to allow the fan duct air to flow from the first duct to the second duct. The system may also include a resonance chamber coupled to the second end of the second duct and configured to allow the air in the resonance chamber to act as a spring causing the air in the second duct to oscillate at a predefined frequency.
