Tunnel Details The 12,000 sq. ft. facility can accommodate a full sized Freightliner cab that is mated to a mock- up box trailer. Wind speeds up to 65 mph by 10, 250 hp industrial blower fans. 30ft long test section

26 ft 21 ft Tunnel cross-sectional area of 550 ft 2

Testing Ability Pressure sensitive floor for calculating trucks drag coefficient. Rotating floor panel to test various angles of attack Smoke wand for flow visualization

Smoke wand enters test section through hole in side of tunnel Wand is manually extended to desired position

Issues with Current Smoke Testing Equipment Smoke wand placement is limited by the length of the wand

Smoke wand range

Issues with Current Smoke Testing Equipment Smoke wand placement is limited by the length of the wand Wand is manually held from outside the tunnel then angled into position, requiring extra personal to perform testing

Issues with Current Smoke Testing Equipment Smoke wand placement is limited by the length of the wand Wand is manually held from outside the tunnel then angled into position, requiring extra personal to perform testing Manual control makes repeatable testing of an area difficult

Issues with Current Smoke Testing Equipment Smoke wand placement is limited by the length of the wand Wand is manually held from outside the tunnel then angled into position, requiring extra personal to perform testing Manual control makes repeatable testing of an area difficult Flexibility of current wand reduces accuracy of smoke placement during testing

Improve smoke testing methods -Increase the testable area within the wind tunnel -Increase stability of the system -Deliver smoke to location of interest accurately -Electronically controlled system to eliminate human error -Provide these requirements while maintaining negligible aerodynamic impact to test region -Delivery of final product by June,16th

Two axis motion – 20’ Horizontal travel – 17’ Vertical travel

PROJECTED AREA 14’ 8.5’

TARGET AREA 17’ 14.5’

Two axis motion – 20’ Horizontal travel – 17’ Vertical travel Zero residual impact when not in use – Removes itself form wind tunnel completely when not in use Aerodynamic Profile – 2-4’ separation between support structure and smoke delivery location (based off structure size)

5.5’ Door Transition

Two axis motion – 20’ Horizontal travel – 17’ Vertical travel Zero residual impact when not in use – Removes itself form wind tunnel completely when not in use Aerodynamic Profile – 2-4’ separation between support structure and smoke delivery location (based off structure size) Remote controlled electronically – No physical interaction for system to operate Accuracy – ± 0.5” Resolution

Concept selection – February 24 th Detailed design completion – April 28 th Fabrication completion – May 31 st Product delivery – June 16 th

Risk Missing delivery date Contractors failure to implement team design Non-function product due to design errors Countermeasure -Well thought out PDS and project plan -Sufficient documentation and walkthrough installation with design team -Budget time for design testing and changes
