Rigging and Repair of Wind Tunnel Motor-Generator Set

Notice ID Number: NIST-SS26-03

Title: Rigging and Repair of Wind Tunnel Motor-Generator Set

Response Date: April 22,2026

The purpose of this sources sought notice is to conduct market research and identify potential sources of commercial products/services that satisfy the Government’s anticipated needs.

BACKGROUND

The NIST Sensor Science Division (SSD) supports the US industrial competitiveness by advancing the next generation of SI-traceable measurements in dimensional metrology, thermodynamics, optical radiation, and fluid flow. The Fluid Metrology Group (FMG) within the SSD maintains standards for realizing gas flow, including air speed. The primary way the FMG provides SI traceability to US industry is by calibrating transfer airspeed measurement devices in the NIST wind tunnel. The NIST wind tunnel is a highly specialized facility originally built in the 1960’s. Recently, the generator half of the motor-generator set in the power system failed and needs to be rebuilt. This current repair request is needed to restore the wind tunnels power system to functional condition.

Scope of Work:

The Contractor shall provide services to repair an existing motor-generator set on the NIST wind tunnel power system. The system shall be restored to operating at full specifications on the nameplate of the machine.

Currently, the generator on the set has failed. The brushes were used beyond their intended life and caused significant damage to the machine. Several brush housings have been damaged, and the commutator worn to the point that the mica filler stands higher than the metal contacts.

Maker: Reliance

Serial Number: 1UP893611T1-KT & 1XP893611A1-JT

Model: 8002A-S & 5808S

NIST property number: N/A

Value: $500,000 (estimate)
