Project Review
Mission Statement: Improve smoke testing methods
Increase the testable area within the wind tunnel
Increase stability of the system
Deliver smoke to location of interest accurately
Provide these requirements while maintaining negligible aerodynamic impact to test region
Delivery of final product by June,16th

Horizontal motionLinear actuator • Pre-fabricated
Roller box• Allows the smoke wand to move in
and out of the tunnel while being supported

Vertical motion
Lifting motor• Drive system
• 700 lb/in • 10 ft/min• 1.5 hp
• Ball screws• 1” X 0.5” (OD X Pitch)• 21’ Long
Trolley• Designed with simple
fabrication and installation in mind

Tunnel sealRolling shutters • Custom fit shutters to prevent pressure
from escaping from the wind tunnel

Roller Box• Stability– Four sets of rollers– Sixteen points of contact
• Adjustability– Two adjustable set
screws/roller assembly
• Angel variation – Upper and lower
brackets are loosened to rotate
