  • System for ensuring failsafe operation of pitot tube covers for multiple types of pitot tubes
    Patent number: 11953516
    Abstract: The present invention is a self-disengaging pitot tube cover having a split cylinder configuration and an internal release mechanism, which is triggered by a temperature sensitive mechanism upon detecting a predetermined temperature so that the pitot tube cover separates and is released from the pitot tube at a predetermined temperature.

  • SYSTEM FOR ENSURING FAILSAFE OPERATION OF PITOT TUBE COVERS FOR MULTIPLE TYPES OF PITOT TUBES
    Publication number: 20230333136
    Abstract: The present invention is a self-disengaging pitot tube cover which is constituted by at least two separable sections where separation of the sections is controlled by temperature sensing and effected by an SMA latch holding the sections together; so that the sections separate from the pitot tube when a particular temperature condition inside the pitot tube occurs.

  • System for ensuring failsafe operation of pitot tube covers for multiple types of pitot tubes
    Patent number: 11740257
    Abstract: A self-disengaging pitot tube cover which is a longitudinally segmented substantially cylindrical structure constituted by at least two separable segments where separation of at least two segments is controlled by temperature sensing and effected by a fusible link holding two adjacent segments together; so that the separated segments lose hold on the pitot tube, when a particular temperature of the pitot tube is reached.

  • Fail-safe pitot cover for a variety of pitot designs
    Patent number: 8132471
    Abstract: A pitot cover is provided with fail-safe removable operation from a pitot tube by virtue of a number of different removal structures. Foremost among these is an elastomeric band which holds two halves of the pitot cover to the pitot tube. The band is separated by an adhesive strip, part of which lies on the pitot tube and melts at less than 230° F. or less.
