  • Fan rub strip in situ machining system and method
    Patent number: 8888418
    Abstract: An in situ fan case rub strip machining tool mounts to a LPT/fan rotor shaft assembly of a gas turbine engine. After a fan is removed therefrom such that the machining tool is rotatable about an engine axis of rotation in conjunction with rotation of the LPT/fan rotor shaft assembly. The machining tool permits machining of a rub strip within the fan case of the gas turbine engine without disassembly of the fan case from the core engine as heretofore required. As the machining tool is mounted to the LPT/fan rotor shaft assembly, the cutting tool is accurately locatable relative the engine axis of rotation such that the rub strip is evenly and precisely machined to be concentric with the engine axis to assure proper fan blade tip to rub strip interface.

  • Multidirectional/rotational superconductor motor
    Patent number: 5015622
    Abstract: A contactless, multi-dimensional small stepper motor with a maximum dimension of less than about 10 centimeters is described. The motor contains at least one magnetized article, at least one superconductive primary suspending element, and at least two primary conductive elements.Each of the primary conductive elements is separated from each adjacent primary conductive element by a distance of from about 0.01 to about 10 millimeters.
