Abstract
An aircraft fairing includes a fairing body having an exterior fairing wall and at least one wheel bin. The at least one wheel bin has a side wall extending from an opening in the exterior fairing wall to an end wall. The side wall and the end wall define a cavity of the at least one wheel bin in fluid communication with the opening in the exterior fairing wall. An acoustic resonator is mounted to an outer surface of the side wall of the at least one wheel bin and is in fluid communication with the cavity. The acoustic resonator has a resonant frequency substantially similar to a cavity modal frequency of the at least one wheel bin at an aircraft flight condition.
Claims16
A method of dampening a pressure buildup in an open wheel bin of an aircraft, the method comprising:
- attaching an acoustic resonator to a side wall of the wheel bin to be in fluid communication with an interior of the wheel bin;
- and
- tuning the acoustic resonator to have a resonant frequency substantially similar to a cavity modal frequency of the wheel bin when the aircraft operates at an aircraft flight condition.
The method as defined in 1, wherein attaching the acoustic resonator includes attaching the acoustic resonator to a location of the side wall where air pressure fluctuation amplitudes are highest.
An aircraft wheel bin, comprising:
- a side wall extending between an opening at one end of the wheel bin to a closed end wall at another end of the wheel bin, the side wall and the end wall defining a cavity of the wheel bin in fluid communication with the opening;
- and
- an acoustic resonator mounted to an outer surface of the side wall and in fluid communication with the cavity, the acoustic resonator having a resonant frequency substantially similar to a cavity modal frequency of the wheel bin at an aircraft flight condition.
