Abstract
An aircraft vertical fin-fuselage structural integration system wherein a plurality of vertical tail fin spars, extending transversely across the fin and fuselage and substantially parallel to the longitudinal axis of the fin, are integrally connected directly to the fuselage pressure bulkhead so as to directly transmit or transfer the vertical fin and horizontal stabilizer empennage loads to the fuselage structural network. The system can be adapted to any type of aircraft, and in the case of an aircraft of the BOEING 727 class, the spars accommodate the air intake S-duct operatively associated with the craft's rear engine housed within the rearwardmost portion of the fuselage. The spars also have their lateral configurations fabricated so as to match the fuselage loft lines.
