Key facts
- Published test section and speed range
- NWTF lists a 2.4 m × 1.8 m test section and maximum flow speed of 45 m/s; its performance block gives a 5–45 m/s flow-speed range.
- Published facility status
- The current NWTF page lists the Cranfield facility as operational and identifies its designation as closed return.
Testing capabilities
Force, pressure and velocity measurement
The facility page lists multiple-channel high-speed data acquisition, with force and moment, pressure and velocity outputs using PIV and a four-channel hot-wire anemometer. It also lists smoke-filament seeding, high-speed video and surface-oil-flow visualisation.
Rolling road and model support
NWTF lists a rolling road with boundary-layer extraction, 6-component overhead, internal and under-floor balances, and four independent wheel-drag load cells. Its specialist-rig listing gives a 1.2 m × 2.77 m rolling road for airspeeds up to 45 m/s with two-stage boundary-layer extraction.
