UNSPSC 41103326: Wind tunnel

Equipment that is utilized to observe and study the phenomenon of air and it proves the theories of hydrodynamics in actual experiment and to measure several types of phenomenon and force working on the object in air. The air flow is artificially generated to find out how the object (model) to be experimented moves in the air in this tunnel-shaped experiment device.

UNSPSC 41103326 Wind tunnel is a Commodity-tier code that covers access to wind tunnel testing facilities and related aerodynamic analysis services. State and local governments use this code to procure wind tunnel time for testing aircraft components, vehicle designs, architectural models, and other structures requiring aerodynamic validation. The work spans facility rental, instrumentation setup, data collection, and technical support from wind tunnel operators during test campaigns. Issuing bodies are primarily state transportation departments, state university systems operating research facilities, and municipal or county airports managing specialized testing infrastructure. Some school districts and regional transit authorities with engineering research programs also solicit under this code when evaluating vehicle or infrastructure designs.

The recent opportunities block contains no entries, indicating no posted state or local wind tunnel solicitations are currently documented in the available sources. This code shows minimal recent procurement activity at the state and local level, suggesting that wind tunnel testing remains a specialized service area with infrequent formal contracting cycles among traditional state and local buyers. Opportunities in this space may be embedded in larger aerospace, transportation, or research infrastructure contracts rather than solicited as standalone wind tunnel services, or may be procured through existing cooperative purchasing agreements or university research consortia without discrete RFP or IFB notice cycles.
