  • Aircraft nacelle assemblies
    Patent number: 9221545
    Abstract: Aircraft nacelle assemblies include a frame, a cowl coupled to the frame, and a biasing member (including a passive mechanism) coupled between the frame and the cowl. The cowl is configured to move between a closed position and an open position. The passive mechanism is configured to provide a biasing force to the cowl. When the cowl is in or near the closed position, the biasing force coupled with the weight of the cowl results in a first net force that urges the cowl away from the open position, and when the cowl is in or near the open position, the biasing force coupled with the weight of the cowl results in a second net force that urges the cowl away from the closed position.
