The facility will be a weather-proof outdoor-type wind tunnel installed on an existing concrete slab. The test section area of the wind tunnel will be enclosed in a pre-engineered metal control room with an approximate interior size of 20? x 30?. The tunnel will have a test section size of 28"H x 40"W x 78"L with a centerline 5? above the floor. The maximum dynamic pressure of the tunnel will be 90 psf. Please see the site layout at: http://www.csupomona.edu/~aro/wt/ DESCRIPTION: The Air Force requires a model support and positioning system, 2 internal force balances and a data acquisition and control system for the new wind tunnel test facility. The contractor shall design, manufacture, deliver, install, demonstrate and document this equipment as specified.
