Replacement Engineering for Electronic Systems

For more than 10 years, Southwest Research Institute (SwRI) has provided replacement engineering services, particularly in electronics, to military and industrial clients. The Institute designs and develops systems and components using state-of-the-art technology to update or replace outdated or unreliable equipment. By inserting advanced technology into existing systems, SwRI can solve problems associated with:

  • Poor reliability
  • Difficult maintenance
  • Unsatisfactory performance
  • Lack of replacement components
  • Unreasonable sole-source pricing
  • Inadequate documentation

As an independent research and development organization conducting research in diverse applications, SwRI provides teams qualified to conduct all aspects of replacement engineering, including:

  • Requirements analysis and definition
  • User interviews
  • Computer-aided analysis and design
  • Market surveys
  • Reliability and maintainability analysis
  • Electronic hardware development
  • Software development
  • Mechanical hardware development
  • Printed circuit board layout
  • Fabrication
  • Installation planning
  • Environmental testing
  • Design documentation
  • Pilot production
  • Competitive procurement

The Institute has re-engineered and replaced a wide variety of ground support equipment for tactical aircraft, including a phase-sensitive voltmeter, which tests synchro resolvers on the F-111, and a precision ratio bridge, which calibrates F-111 fuel system components. SwRI also developed this portable battery-powered instrument to periodically test the chaff and flare dispenser systems of tactical aircraft.



Using computer-aided engineering (CAE), SwRI analyzes existing designs, to evaluate potential replacement designs, and new designs under development. The system supports the modeling and simulation of both digital and analog electronics.



Industry uses replacement engineering to maintain or enhance equipment. The Institute automated the control of this terminal crimping machine, used to manufacture wire harnesses for critical automotive systems.
