Design

Turbine Generator DesignFor more than 45 years, Barber-Nichols Inc. (BNI) has been designing specialty turbomachinery for dozens of industries and this diverse experience helps us develop innovative solutions to difficult projects. A well-honed design process that combines knowledge and heritage with formal design reviews and risk mitigation ensures success. Additionally, Barber-Nichols employs highly knowledgeable and experienced people who work to understand how the turbomachinery we are designing fits into the overall system to flush out potential problems.

Motor & Bearing Design

When a machine's performance requirements exceed what is commercially available from conventional manufacturers, BNI has the in-house capability to design and produce specialized alternators, generators, motors, and bearings. Barber-Nichols uses Motorsoft SPEED® to design custom alternators, generators, and motors which can range in power from a fraction of a Watt to 250 kW and in speed from 1,000 rpm to 200,000 rpm. BNI's bearing expertise is broad based and includes many types of bearings, lubricants, and coolants for many different applications. BNI has experience with high-speed bearings, hydrodynamic bearings, cryogenic fluid lubricated bearings, grease lubricated bearings, hydrostatic bearings, and magnetic bearings. Additionally, Barber-Nichols designs and fabricates ceramic hybrid bearings that are lubricated with the following low lubricity process fluids:

  • Liquid Oxygen
  • Liquid Hydrogen
  • Liquid Nitrogen
  • Hydrogen Peroxide
  • Kerosene
  • Liquid Helium
  • Toluene
  • High Temperature Water (Greater Than 150 °C [300 °F])

Design for Manufacturability (DFM)

Because BNI is equal part machine shop and equal part engineering firm, Design for Manufacturability (DFM) is more than just a concept, it is a daily reality. BNI has a strong corporate culture of open communication where engineering and manufacturing personnel exchange ideas directly in both formal and informal settings. Barber-Nichols also incorporates the concepts of Design for Assembly and Design for Cost into its DFM program. Research indicates that 75% of a product's cost is established during the design process.

Design For Manufacturability

Gearbox Design For ManufacturabilityBarber-Nichols Inc. (BNI) and the Applied Research Laboratory (ARL) located at Pennsylvania State University applied Design for Manufacturability (DFM) principles to the U.S. Navy's Anti-Torpedo Torpedo (ATT) development project. ATT is a defensive torpedo that will track, actively engage, and disable an offensive torpedo before it can damage or sink a ship. BNI and ARL initially began working together on the ATT's advanced propulsion system and gearbox. Shortly thereafter, BNI proposed the entire torpedo design should be reviewed for manufacturability. The effort cut ATT production costs by 20 percent. The U.S. Navy is planning to manufacture the ATT for ten years and the additional funds spent on Design for Manufacturability will be fully recouped in the first year.
