FIELD: transport.SUBSTANCE: invention relates to aircraft industry and concerns development of aircraft pressure bulkhead assembly structure. Pressure bulkhead assembly structure for connection of front fuselage section corresponding to pressure compartment of fuselage and rear fuselage section corresponding to unpressurised compartment contains bosom plate, forming frame, fish-plate and tensile fittings. The bosom plate goes along fuselage contour and has form of angle with front portion and rear portion. The rear portion goes inclined up and back and is connected with bulkhead. The forming frame goes along fuselage contour and has top flange, wall and bottom flange. Bottom flange of frame is connected with front portion of bosom plate. The fish-plate goes along fuselage contour and is located between front portion of bosom plate and fuselage sheath. Fittings are located between the fish-plate and fuselage stringers.EFFECT: joint strength, structure rigidity, redistribution of loads in direction of fuselage sections.15 cl, 3 dwg |
