摘要： A turbine blisk is provided. The turbine blisk includes an inner rim, a plurality of adjacent rotor blades extending radially outward from said inner rim, a shroud segment integrally coupled to each of the plurality of adjacent rotor blades, thereby forming a plurality of adjacent shroud segments, and a gap defined between each of the adjacent shroud segments. The gap has a geometry that facilitates interlocking the plurality of adjacent shroud segments when a torsional force is applied to the plurality of adjacent rotor blades.

摘要： Various embodiments of a circuit breaker are described where a movable bridge connector is employed as part of the conductive path when the circuit breaker is in a closed configuration. When the circuit is opened, the connector is displaced from the two fixed contacts otherwise bridged by the connector. In one such embodiment, the circuit breaker utilizes the electromagnetic forces generated in response to the opening event to break the circuit.

摘要： Embodiments of a tri-stable flexure mechanism are described where a resilient component is present that serves as both a structural component in the kinematic chain of the mechanism and as energy storing component of the mechanism. The resilient component maintains a movable arm and an input link in either a first stable state or a second stable state when the ends of the resilient component are held in place so that the resilient component has a state of high elastic strain energy. In a third stable state, where the resilient component is in a relaxed state of lower elastic strain energy, the mechanism may be in a tripped state distinct from the closed and open states.
