1. Description:
Flange F-02 is the T-stoff flange and sits at the top of the T-stoff tank battery. The flange will be constructed out of 1100 aluminum alloy 1/16 inch thick and the proposed flange is 6 inches in diameter. The T-stoff tanks will be attached to the flange through the 3 large holes and it is assumed that the forces applied to the flange will be transmitted through those holes. For the worst case scenario, we will assume the the total predicted thrust is transmitted directly through the T-stoff tanks. The 3 outer holes will be attached to the internal support structure, the middle hole will be used to align the gasoline line, and the skin will sit along the outer edge of the flange. For this scenario, it is assumed that the flange is immovable in all directions at these points.

10. Conclusion:
It appears that the flange F-02, as designed, will be able to withstand the predicted static loading. The computer analysis indicates that the flange has a minimum factor of safety of 2.3, so the flange can still be further modified in the low stress and strain areas while maintaining it ability to perform as needed. Modification would require further studies.
