Formed Sheet Heat Exchanger

View page
US Patent:
7988447, Aug 2, 2011
Filed:
Oct 29, 2007
Appl. No.:
11/926555
Inventors:
Scott W. Fowser - Chatsworth CA, US
Mark D. Horn - Granada Hills CA, US
Andreas C. Straub - Costa Mesa CA, US
Jon C. Wagner - Thousand Oaks CA, US
Assignee:
The Boeing Company - Chicago IL
International Classification:
F28C 3/00
F28C 3/02
F28D 9/00
F28F 3/00
US Classification:
431217, 431 11, 431207, 431210, 431213, 431215, 60723, 60777, 126116 R, 165166
Abstract:
A formed sheet heat exchanger is provided for exchanging heat between fluids is provided. The apparatus includes flow divider sheets that are positioned in a stacked configuration and extend in a longitudinal direction so that adjacent pairs of the sheets define flow passages therebetween for receiving first and second fluids. Each of the sheets is nonuniform in the longitudinal direction, having a manifold portion and a corrugated portion. The corrugated portions of each adjacent pair of sheets define a plurality of fluid channels therebetween that are connected to the portion of the flow passage defined between the manifold portions. The fluid channels are configured to receive the first or second fluids and transfer thermal energy therebetween through the flow divider sheets.

Method Of Fabricating A Fiber-Reinforced Ceramic Matrix Composite Part

US Patent:
61362379, Oct 24, 2000
Filed:
Apr 13, 1999
Appl. No.:
9/290450
Inventors:
Andreas Straub - Tarzana CA
Jerry Brockmeyer - Valencia CA
Eric Krieg - Simi Valley CA
Assignee:
The Boeing Company - Seattle WA
International Classification:
B29B 1500
US Classification:
264 401
Abstract:
A method for fabricating a fiber-reinforced ceramic matrix composite (FRCMC) part includes the steps of forming a blank from FRCMC material such that the blank has a dimension approximating a desired finished dimension for the part measuring the dimension of the blank in an unloaded condition, applying a load to the blank and then removing the load so as to cause permanent strain of the blank, measuring the dimension of the blank after the load has been applied and then removed, and comparing the measured dimension after loading to the previously measured dimension. In a preferred embodiment of the invention, if the dimension after loading differs from the dimension previously measured, the loading and measuring steps are repeated. After each loading cycle, the blank is measured and the measured dimension is compared to that previously measured after the prior loading cycle. The loading cycles are continued until the measured dimension differs from the previously measured dimension by less than a predetermined amount such that the blank has achieved dimensional stability with loading.
