3x3 Wind Tunnel Resources for Students

Training: After submitting a request for tunnel time, all 3X3 users must complete the required EHS online training modules and attend on-site safety and operational training with the Test Engineer. Email wind3x3@uw.edu to schedule.

Tunnel Operation: Please refer to this short operation manual for a reminder of tunnel controls once your initial training is complete.

Health and Safety: All users of the tunnel must complete the following list of online EHS safety courses.

Standard equipment: The following standard equipment is available for Junior design projects and Capstones. Notification must be given prior to your scheduled wind tunnel time of which equipment you desire to use.
