While the HALO wind tunnel is capable of aerodynamic, aeroacoustic, and racing testing, the facility is only open to external users for aeroacoustic testing or testing involving wind-only needs.

The wind tunnel can achieve a speed range up to 310 kph (192 mph).

Thanks to the heat exchanger, the HALO wind tunnel can test from 10-50⁰ Celsius (50-122⁰ Fahrenheit).

There are a series of microphone arrays—top, front, sides, and interior—made up of 502 external microphones and cameras and 54 internal microphones for use for sound source detection. Aachen heads are also utilized for interior vehicle acoustic analysis. This aeroacoustic array system has an external noise source accuracy of 5.0 cm.

The HALO wind tunnel is incredibly efficient when progressing from one test to the next. Two key components that make this possible.

1. First, the test plan is preloaded into the control system. After the desired wind speed is reached, the data acquisition system starts gathering data. When data collection is complete, the control system advances to the next test step.
2. Secondly, the speed at which conditions stabilize—allowing repeatable data to be gathered—is 20 seconds.

Turntable: The 12-meter turntable, where the item to be tested is secured, can rotate 180⁰.
Access: There are two doorways to the test section, allowing for efficient loading and unloading.
Spacious: The control room was designed with adequate space for your entire team.

We can load a vehicle into the test section in less than 30 minutes.

Each customer will have secure badge-controlled access to a shop bay with tools, a surface plate, work benches, a kitchenette, restroom, and a private office area with conference room.

When your testing session begins, not only is the control room large enough for your entire team, and it also provides a dedicated break area, private meeting room, and work bench for any minor part modifications.

Our badge reader system allows zone control so that all wind tunnel users maintain strict confidentiality.

As testing progresses, your data will continually be written to a removable, passcode-protected hard drive that you will take with you upon completion of your testing.

Results are viewable in real-time as testing progresses. You can do any additional post-processing and analysis utilizing the raw files on the secure hard drive provided.

Yes. To support confidentiality in the facility, a digital camera with a new memory card will be provided for your use during your test session. The memory card is yours to take with you upon completion of your testing.

We also have video cameras in the test section, and any video footage recorded during your testing time can be downloaded for your use.

You are permitted to take pictures in your bay area, office areas, and in the test section during your test.

Leading up to your test, a program manager will be your main point of contact. While onsite, you will primarily be working with a tunnel operator, test technician, and acoustic engineer (as needed).

Only the customer team and the third-party contractors who will be supporting your test. The badge reader system we use allows zone control and ensures strict confidentiality.

We’ll work with you about what setting, filters, and other needs you have for your tests. We will have an engineer onsite during testing to support post-processing. If you would like to do additional data analysis after leaving the HALO wind tunnel, we can provide contacts for the appropriate licensing.

Your test session will run 7:00 a.m. – 4:30 p.m., continuously. Testing is available on Saturday and Sunday.

Due to the continuous testing cycle, we provide lunch and a full assortment of snacks and beverages throughout your test session. We do not stop testing for breaks, unless you opt to have a break.

Our testing hours are 7:00 a.m. – 4:30 p.m. daily. Site access is available 6:30 a.m. – 5:00 p.m.
