Abstract:
A reinforcement system for an aircraft comprising a fuselage frame aluminum skin, and fuselage frame aluminum skin being attached to a fuselage frame of said aircraft, wherein the system provides additional reinforcement to said aircraft without replacing any of its elements, the improvement comprising:(a) one or more fuselage section fabric jackets constructed of a lightweight, high performance solid fabric, with physical properties including: reduced air permeability, high tensile strength, high modulus and stiffness, and resistance to impact, punctures, cuts, tears, wear, fatigue, creep, repeated flexing, stretching, chemicals and corrosion, and thermal resistance to shrinking and cracking at high and low temperature extremes, fire, smoke and toxic gases; and(b) one or more said fuselage section fabric jackets installed between said fuselage frame aluminum skin and fuselage frame metal external paneling, covering one or more fuselage sections of entire said fuselage frame of said aircraft; and(c) said fuselage frame metal external paneling installed between said fuselage section fabric jackets and outside surface of entire said fuselage frame of said aircraft; and(d) an adhesive, bonding said fuselage section fabric to said fuselage frame aluminum skin and to said fuselage metal external paneling, preventing premature crimping, abrasion and tearing of said fuselage section fabric jackets, and rivet failure; and(e) an installation completed by riveting through in sequence: said fuselage frame aluminum skin, said adhesive, said fuselage section fabric jackets, said adhesive, said fuselage frame metal external paneling, into entire said fuselage frame of said aircraft.
