  • Aircraft cabin outflow valve including aft door modified for noise suppression
    Patent number: 6116541
    Abstract: An outflow valve for a cabin pressure control system of an aircraft cabin includes an aft door that is modified to disrupt or increase speed of cabin air flowing past the aft door and out of the outflow valve. The aft door may be modified by notches formed in its leading edge. In the alternative, the aft door may be modified by through-holes formed behind the leading edge. The outflow valve also includes a forward door. Bolt heads or a baffle may protrude from an inner surface of the forward door to disrupt or slow down cabin air flowing over the inner surface of the forward door and out of the outflow valve.
