  • Aerospace Aerospace


    Aircraft engine manufacturers employ BSi equipment to meet Federal Aviation Administration (FAA) and Joint Aviation Requirements (JAR) to qualify new rotor designs. Not only that, but from the R&D performed to evaluate new materials and designs to pre-spinning production rotors as part of the manufacturing process, BSi equipment is on the job.

  • Automotive Automotive


    For many years Barbour Stockwell has supplied the ultra high speed spin rigs needed for testing automotive turbochargers. Often overspeed tests are part of the production process; driving rough machined impellers to yield prior to final machining. A more recent development has been the employment of the company’s rigs to perform overspeed, burst and low cycle fatigue testing of Electric Vehicle motor rotors.

    Power Generation

    Barbour Stockwell has provided spin test facilities for processing gas turbine rotors by performing overspeed tests at cryogenic and elevated temperatures. Frequently the rotors are driven past the point where the bores yield. BSi designs and manufactures the complex tooling required to maintain concentricity notwithstanding the extreme plastic strains.

    BSi spin rigs are employed by manufacturers of grinding wheels to perform the overspeed tests specified by ANSI Standard B7.1. Burst testing of samples from a production lot is also used for quality assurance as well as in the qualification of new products.
