Overview Schedule Frame Analysis Attenuator Carbon Fiber A- Arms Conclusion

Schedule

Frame Computer Analysis Complete! Actual Testing of Main Hoop Hard Test starts Nov. 19 th using strain gauges Horizontal bending Longitudinal Torsion

Frame continued Quality Assurance 2 of 4 QA tests complete Weld Quality, (in progress) 37 of 42 test sites completed 8 unsat, (Being Fixed) QA still in progress Welding finished soon Wall Thickness (Pending) Alternative Frame Rules, (50% done) Proposed Method based on Hard analysis results.

Attenuator Materials Difficulty Estimated ship time 2 days Changed to 2 weeks! New Material Galvanized Steel 25 mm thickness, 1” cell size Current Status Fabrication completed! Soft Testing calculations altered Hard Testing moved to next week

Carbon Fiber A-arms Actual testing of assembly, Nov. 9 th Verify will meet track conditions Destructive testing required for 1000 lbs Going to complete testing and fully analyze, SF=1.2

Conclusion Frame  Weight test Nov 19 th Attenuator  Drop test next week A-Arms  Pull tests Nov. 9 th Complete the paper!
