Abstract:
This application provides for flexible load bearing connectors (FLBCs) systems and methods and for monitoring, reporting, and responding to the performance and/or health of the FLBC. The system provided is an instrumented FLBC that can at least one of sense, record, report, react to and/or otherwise make use of performance and/or health information of the FLBC. The performance and/or health information can include any information related to movement (such as displacements and/or relative motions) of the FLBC and/or the system components the FLBC joins together and/or loads, vibrations, shocks, and environmental exposures the FLBC receives, transmits, supports, and/or experiences.
Abstract:
One aspect is a structural fault estimation system for a rotor system. The structural fault estimation system includes a plurality of sensors operable to provide a plurality of measured rotor loads and motion of the rotor system. A rotor loads and motion estimator is operable to produce a plurality of estimated rotor loads and motion for the rotor system. A rotor fault estimator is operable to determine residual rotor loads and motion as a difference between the measured rotor loads and motion and the estimated rotor loads and motion, and estimate fault magnitudes for the rotor system using least squares relative to fault models and the residual rotor loads and motion. The structural fault estimation system can perform structural fault estimation in real-time on an aircraft while in operation.
Abstract:
Es ist ein hydrodynamisches Gleitlager (1) zur Lagerung einer Welle (9) offenbart, das mindestens ein Gleitelement (5) mit einer Gleitfläche (6) umfasst. Erfindungsgemäß ist auf mindestens einen Gleitelement (5) mindestens ein Sensor (11) aufgebracht, der aus einem funktionellen Schichtsystem (13) aufgebaut ist.. Von einem Signalabgriffselement (15) des Sensors (11) werden dann über mindestens eine elektrische Leitung (17) die Messwerte an eine Auswerteeinheit (19) geleitet. Anschließend werden in der Auswerteeinheit (19) die Messwerte ausgewertet und daraus im Betrieb des hydrodynamischen Gleitlagers (1) Aussagen über den Betriebszustand des hydrodynamischen Gleitlagers (1) mit Blick auf Lasten, Verformung und Temperatur abgeleitet.
Abstract:
A flywheel energy storage system incorporates various embodiments in design and processing to achieve a very high ratio of energy stored per unit cost. The system uses a high-strength steel rotor rotating in a vacuum envelope. The rotor has a geometry that ensures high yield strength throughout its cross-section using various low-cost quenched and tempered alloy steels. Low-cost is also achieved by forging the rotor in a single piece with integral shafts. A high energy density is achieved with adequate safety margins through a pre-conditioning treatment. The bearing and suspension system utilizes an electromagnet that off-loads the rotor allowing for the use of low-cost, conventional rolling contact bearings over an operating lifetime of several years.
Abstract:
A bearing comprises a bearing ring and rolling elements, whereby the bearing ring comprises an outer surface, having a groove around its circumference accommodating a fibre sensor. The bearing further comprises a clamping element, engaging the fibre sensor with a clamping force acting in a radial direction of the bearing ring such that the fibre sensor intimately engages the bearing ring. Due to the clamping force, relative movement of the fibre sensor may be reduced.
Abstract:
A housing device (1), provided with a system (9) for detecting the load applied to an element ( 15) arranged in said housing (1), comprises an inner part (3) adapted to support said element ( 15) and an outer part (2), said inner and outer parts (2, 3) being linked by at least two deformable connecting elements (5, 6), such that the inner part (3) may be displaced relative to the outer part (2) under the action of a load applied to said element (15), the system (9) for detecting the applied load comprising first detection means ( 10) for directly detecting the displacement of one of the parts (3), relative to the other part (2), under the action of a load applied to said element (15). Said housing (1) comprises a deformable ring (7) mounted in the bore (3a) of the inner part (3).
