Small Business Innovation Research
Integrated Turbopump Design System for Improved
Performance and Reduced Cost
Concepts ETI, Inc. White River Junction, Vermont
INNOVATION Empowers turbopump designers to
evaluate performance versus manufacturing
cost/assembly efficacy early in, and throughout,
the new product development process. Integrates
all of the software tools required to perform
turbopump scoping evaluations, design work, and
manufacturing cost/assembly assessment in an
agile PC system for use by well-trained (not
necessarily experts) multi-disciplinary design
engineers. Turbopumps are a key component in a
rocket engine.

• ACCOMPLISHMENTS
• Design for manufacture and assembly (DFMA)
  procedures and software integrated into the agile
  engineering design system.
• DFMA used to analyze NASAs Fastrac (X-34)
  turbopump, leading to recommendations for
  reducing the parts inventory by 1/2 and assembly
  time by 1/3 (without a major redesign).
• Developed turbopump design guidelines based on 17
  different rocket turbopump stages. May be the
  most complete set of data available for
  turbopumps.
• Plans set to incorporate NASAs GFSSP code and
  more integrated life (including thermal and
  transient analysis) evaluations into the agile
  engineering process.
• Over 995,000 in additional (mostly
  non-government) revenue due to the recently
  completed Phase II SBIR project. Over 5,500,000
  in additional revenue is forecast from 2000 to
  2004 as a direct result of the Phase II SBIR
  project.

• New users for pump applications as a result of
  the Phase II SBIR project include Hamilton
  Sundstrand, Cryogenic Experts, Bombardier,
  Westinghouse, and Williams International.
  (Initial revenue generated equals 422,000.)

• COMMERCIALIZATION
• The entire process is marketed as the Agile
  Engineering Design System ? (very similar to
  NASAs Intelligent Synthesis Environment, ISE).
• System includes integrated individual software
  products for centrifugal pump and axial turbine
  design and development. (Similar products are
  also available for axial and centrifugal
  compressors and radial turbines).
• Marketed to pump, compressor, and turbine
  manufacturers for both industrial and aerospace
  applications.
• During the approximate time period covered by the
  Phase II SBIR (calendar years 1998 and 1999),
  select CETI software users known as the Advanced
  Users Group (AUG) provided 1,147,000 for
  additional software program enhancements.
• As AUG members, the companies directly benefited
  from SBIR funded work, thereby demonstrating the
  dual-use nature of the Phase II SBIR work. Over
  700,000 in non-government AUG funds are being
  used for ongoing system enhancements in 2000.

• GOVERNMENT/SCIENCE APPLICATIONS
• In addition to over 80 industrial and aerospace
  companies, NASA MSFC is now a user of the Agile
  Engineering Design System ?.
• MSFC has recently used part of the system to
  evaluate potential design modifications
  to the Fastrac turbopump.
• SBIR product developed could reduce component
  development cost by half.
• Tools will be used for future generation Reusable
  Launch Vehicle (RLV) turbomachinery systems
  to help meet cost targets.
