VAROC Air Dynamometers: Success story with the Swedish Navy

The Swedish Navy recently purchased a VAROC Air Dynamometer to test engines on their line of Visby-class corvette naval warships, the first vessel in the world to have fully developed stealth technology.

In addition to the VAROC dynamometer, Concepts NREC supported the Swedish Navy with the design, integration, testing, validation, and commissioning of a test cell that allows for full mobile deployment between multiple sites. The following 3-minute video provides more details on the cell and our partnership with the Swedish Defence Material Administration ("Försvarets Materielverk"; known as FMV) on this program.

The Concepts NREC family of VAROC Air Dynamometers are proudly manufactured in the USA and have been used by military and commercial organizations throughout the world for over 35 years, establishing a new standard for testing turboshaft engines for helicopters, power generation, and marine applications. Branches of the U.S. military use the VAROC to test Apache, Black Hawk, and Chinook engines before they are reinstalled to help ensure the safety of the pilots and crew.

By using ambient air ranging from -40°C to 40°C as the working fluid, VAROC dynamometers offer enhanced ease-of-use, reliability, control, and portability relative to other load-testing devices.  

The VAROC family of air dynamometers are a good example of Concepts NREC’s commitment to stay on the forefront of turbomachinery innovation, technology, and development and our reputation for delivering on projects that continually push the limits of what's thought to be possible.
