Abstract: As turbomachinery systems continue to push the limits of modern technology, the modeling techniques being developed also continue to push modern computational limits. While modeling the pristine system during the design ...

Abstract: Nonsynchronous vibrations are a difficult problem to address for turbomachines due to the complex nature of the forcing. Such vibrations can be caused by vortex shedding, flow instabilities, stall cells, or flutter. Testing ...

Abstract: Abstract. Bladed disks and blisks are designed to be cyclic structures that ideally have identical sectors. There will, however, always be mistuning, which is blade-to-blade differences that break the cyclic symmetry of ...

Abstract: Current efforts to model multistage turbomachinery systems rely on calculating independent constraint modes for each degree-of-freedom (DOF) on the boundary between stages. While this approach works, it is computationally ...

Abstract: This work investigated the damage severity of an unmanned aerial vehicle (UAV) ingestion into fan models of a midsized business jet engine. The ingestion of the quadcopter UAV model into the fan was carried out in ls-dyna. ...

Abstract: In this paper, an efficient and accurate computational method for determining responses of high-dimensional bilinear systems is developed. Predicting the dynamics of bilinear systems is computationally challenging since ...

Abstract: A considerable amount of research has been conducted to develop reduced order models (ROMs) of bladed disks that can be constructed using single sector calculations when there is mistuning present. A variety of methods ...
