Appl. No.:

10/972916

Inventors:

Anapathur V. Ramesh - Bothell WA, US
Paul M. Covert - Lynnwood WA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

G06Q 99/00

US Classification:

705400, 705 11, 705 712, 705 737, 702184

Abstract:

The method and system quantify the impact of various design and operational solutions for equipment modules of a structure and the overall structure based upon economic factors. In particular, the method and system provide cost evaluation of various maintenance approaches for at least one equipment module that is part of an overall structure. In addition, a baseline and alternate equipment module may be specified for each equipment module. The costs associated with each of the maintenance approaches for each baseline and alternate equipment module then may be compared and the costs associated with the overall structure having a chosen maintenance approach for each baseline and alternate equipment module may be evaluated. The sensitivity of the costs associated with the overall structure to changes in one or more of the parameter values also may be calculated.

International Classification:

F01D 11/18
F01D 11/02
F01D 25/00

Abstract:

A passive clearance control limits thermal expansion between stator components relative to rotor components. A control ring controls clearance in a passive manner and is located on or adjacent to stationary components which thermally expand during engine operation. The control ring is formed of material having low coefficient of thermal expansion such as CMCs (Ceramic Matrix Composites) and therefore limits, inhibits or restrains expansion of the adjacent stator components as temperatures increase. Limiting expansion of the stator component reduces rotor/stator clearances and limits parasitic leakage of fluid along the flow path through the engine core.
