Contract: FA8201-07-C-0074
Award Amount: $749,928.00


The Department of Defense (DOD) has many requirements for support structures that possess sufficient strength and rigidity for general purpose communications and radar applications. Steel support structures are generally used, but are subject to corrosion and require frequent maintenance. The goal of the topic is to design and develop a composite structure to functionally replace the current steel structures. The design must meet the necessary strength, rigidity, and fatigue requirements while providing superior corrosion resistance and durability. During the Phase I effort, Ebert validated the concept designing a 20 foot tall structure capable of supporting a 20,000 lb. mass and with a natural frequency greater than 5 Hz. In addition, a top equipment support platform was designed to interface the tower with communication or radar antennas. This platform design uses a grid of girders constructed of composite sandwich panel. This results in a rigid platform that effectively transmits the load to the tower legs and maintains the overall 5 Hz. requirement with the load mass centered on the platform. The Phase II effort will produce a demonstration tower constructed of composite pultruded components and assembled and erected on an Air Force designated test site.
