ABB has completed a major modernization of the variable speed drive (VSD) system powering NASA’s National Transonic Facility (NTF), significantly extending the operational life of the facility by at least 10 years.
Located at NASA’s Langley Research Center in Hampton, Virginia, the NTF is the world’s largest medium voltage (MV) drive system and has played a critical role in high-speed aerodynamic testing of platforms including the Boeing 777, the Space Shuttle, and its Booster Rocket.
Originally supplied by ABB in 1997, the 101-megawatt drive enables the NTF to simulate real-world transonic flight conditions by channeling air or nitrogen at high altitudes and near-supersonic speeds. The tunnel supports ambient and cryogenic testing environments, providing NASA with a uniquely capable aerodynamic research platform.
In 2021, aging of the original drive’s components prompted NASA to initiate an upgrade. ABB engineers assessed the electrical and mechanical systems and designed a modernization solution that replaced only the drive’s small part—the control unit—within the existing physical footprint. This approach limited project disruption, minimized waste, and reinforced ABB’s circular engineering approach.
“NASA relied on ABB’s domain expertise, technology and services to ensure its National Transonic Facility (NTF) provides high reliability and uptime to maximize availability for its testing programs – and optimize the life-cycle value of its assets,” said Oswald Deuchar, Head of Modernization Services, ABB Motion. “Extending the life of the wind tunnel by at least 10 years supports NASA’s operational goals, while upgrading the drive’s key components demonstrates efficiency and circular approach.”
The modernization was carried out under a broader ABB Motion OneCare service agreement. In addition to the drive upgrade, the agreement provides NASA with tailored support for spare parts and maintenance to extend asset life while improving system uptime and energy efficiency.
The renewed drive system will support critical NASA test programs by maintaining consistent operational availability, now powered by ABB’s latest high-efficiency power electronics and control technology.
