5. AAE450 Spring 2009 Welded Joint Pinned Joint Four Member Truss Support System [Korey LeMond] [STRC/THM/INTEG/CAD GL, Locomotion Phase] 5 Aluminum Truss System with total weight of 3.25 kg

6. AAE450 Spring 2009 Payload Fairing Adapter Rivet Holes to attach to OTV Aluminum part with total weight of 10.3 kg, but can be jettisoned with PyroBolts before TLI [Korey LeMond] [STRC/THM/INTEG/CAD GL, Locomotion Phase] 6

7. AAE450 Spring 2009 Truss Support Pad Ultra thin pad to hold Xe tank in place Rivet [Korey LeMond] [STRC/THM/INTEG/CAD GL, Locomotion Phase] 7 Serves to keep Xe tank in place, more than likely two rings will be needed. Three pads are connected to each ring, although only one is shown. The entire system weighs 1 kg. Welded Joint directly onto Truss Support System

8. AAE450 Spring 2009 C-Channel Stiffener Curved face to rivet or braze directly onto shear panel. Rivets introduce stress risers, while brazing the components together results in a joint 1/3 the strength of the Mg alloy Entire C-Channel system of 6 C-Channels weighs only 6 kg total.

9. AAE450 Spring 2009 Shear Paneling.0005 mm thick sheet of wrought Magnesium Alloy, either riveted together upon overlap, brazed upon overlap, or bonded with adhesive to form a lap joint Serves as a surface to conduct heat away from the electronics module, to protect all components from incident radiation, as an integration interface for all vital structural components and solar arrays, and weighs 9 kg.
