F.7.3 Front Bulkhead Support

F.7.3.1  In addition to proving that the strength of the monocoque is sufficient, the monocoque must have equivalent EI to the sum of the EI of the six Steel Tubes (F.3.2.1.b) that it replaces.

F.7.3.2  The EI of the vertical side of the Front Bulkhead support structure must be equivalent to or greater than the EI of one steel tube that it replaces when calculated as per F.4.4

F.7.3.3  The perimeter shear strength of the monocoque laminate in the Front Bulkhead support structure must be 4 kN or more for a section with a diameter of 25 mm. This must be proven by a physical test completed per F.4.3.5 and the results included in the SES.
