  • Patent number: 4616793
    Abstract: This is a device for suspending a store 66 from an aerodynamic support surface, such as an aircraft wing 12, and more specifically for improving upon single pivot decoupler pylons by reducing both frequency of active store alignment and alignment system space and power requirements. In the described embodiment, two links 36 and 42 suspend a lower pylon/rack section 60, and releasably attached store 66, from an upper pylon section 16 mounted under wing 12. Links 36 and 42 allow lower pylon section 66 to rotate in pitch about a remote pivot point 68. A leaf spring 30 connected between lower section 60 and electrical alignment system servomechanism 18 provides pitch alignment of the lower section 60/store 66 combination. Servomechanism 18 utilizes an electric servomotor 20 to drive gear train 21 and reversibly move leaf spring 30, thereby maintaining the pitch attitude of store 66 within acceptable limits. Damper 54 strokes when lower section 60 rotates to damp large oscillations of store 66.
