1. Description:
Flange F-04 is the pressure manifold support flange. The flange will be constructed from 1/16 inch thick1100 Aluminum alloy with an approximate diameter of 6 inches. In this configuration the pressure manifold is mounted through the central hole and is connected to a rigid pipe that attaches to the pressure reservoir. The worst case scenario for this flange will be if the support structure slips and transmits the total thrust through the outer three holes. Since the manifold is mounted to a rigid pipe, the central hole is considered to me stationary. The outer edge of the flange will fit tightly against the inner diameter of the skin, so it is also considered immovable. The pressure manifold will be attached to the T-stoff and gasoline tanks via flexible tubing, so it is free to move.

10. Conclusion:
It appears that the flange will have no problem surviving in this situation. The minimum factor of safety is 3.0, so the flange can be further modified in low stress and strain areas. For now the flange will remain as is to allow other design issues to be addressed, after which further test will reveal the areas where we can save weight.
