초록 ▼

A hybrid metal and composite spool includes metal rings on an outer diameter of a composite spool shell. Metal rings may include features such as annular or axial dovetail slots. Adhesive layers may be between the metal rings and composite shell which may be connected by a shrink bonded joint. The metal rings may include a single seal tooth ring with an annular radially extending seal tooth. A method for fabricating the spool may include fabricating one or more metal rings with the features therein, positioning the metal rings in place on an outer surface of an uncured composite spool shell of the spool before curing the shell, and curing the shell with the one or more metal rings positioned in place. Alternatively, rings may be heated to a temperature at least sufficient to slide rings over a cured composite shell, and allowed to cool and shrink onto shell.

1. A hybrid metal and composite spool comprising one or more metal rings on an outer diameter or an outer surface of a composite spool shell of the spool; wherein the metal rings include forward and aft dovetail slot metal rings,an axially aftwardly extending annular tooth attached to the forward dovetail slot metal ring, andan axially forwardly extending annular tooth attached to the aft dovetail slot metal ring. 2. The hybrid metal and composite spool as claimed in claim 1 further comprising features in the one or more metal rings. 3. The hybrid metal and composite spool as claimed in claim 2 further comprising a shrink bonded joint between the one or more metal rings and the composite spool shell. 4. The hybrid metal and composite spool as claimed in claim 2 further comprising one or more annular adhesive layers between the one or more metal rings and the composite spool shell. 5. The hybrid metal and composite spool as claimed in claim 4 further comprising a shrink bonded joint including the annular adhesive layers between the one or more metal rings and the composite spool shell. 6. The hybrid metal and composite spool as claimed in claim 2 further comprising the features including dovetail slots in the metal rings. 7. The hybrid metal and composite spool as claimed in claim 6 further comprising one or more annular adhesive layers between the one or more metal rings and the composite spool shell. 8. The hybrid metal and composite spool as claimed in claim 7 further comprising a shrink bonded joint including the annular adhesive layers between the one or more metal rings and the composite spool shell. 9. The hybrid metal and composite spool as claimed in claim 1 further comprising the metal rings including at least one single seal tooth ring with an annular radially extending tooth. 10. The hybrid metal and composite spool as claimed in claim 9 further comprising one or more annular adhesive layers between the one or more metal rings and the composite spool shell. 11. The hybrid metal and composite spool as claimed in claim 10 further comprising a shrink bonded joint including the annular adhesive layers between the one or more metal rings and the composite spool shell. 12. The hybrid metal and composite spool as claimed in claim 1 further comprising the metal rings including at least one multi-tooth seal tooth ring having at least two annular axially spaced apart seal teeth radially extending away from an annular base connecting the at least two annular axially spaced apart seal teeth. 13. The hybrid metal and compost e spool as claimed in claim 12 further comprising one or more annular adhesive layers between the one or more metal rings and the composite spool shell. 14. The hybrid metal and composite spool as claimed in claim 13 further comprising a shrink bonded joint including the annular adhesive layers between the one or more metal rings and the composite spool shell. 15. A method for fabricating a hybrid metal and composite spool comprising: fabricating one or more metal rings with features therein,positioning the one or more metal rings in place outer surface and/or an inner surface of an uncured composite spool shell of the spool before curing the shell, andcuring the shell with the one or more metal rings positioned in place on the outer surface and/or the inner surface;further comprising bonding the one or more metal rings to the uncured composite spool shell by applying one or more annular adhesive layers between the one or more metal rings and the composite spool shell before the curing. 16. A method for fabricating a hybrid metal and composite spool comprising: fabricating or e or ore metal rings with features therein,heating the one or more metal rings to a temperature at least sufficient to slide the rings over a cured composite spool shell, p1 sliding the heated one or more metal rings in place on an outer surface of the cured composite spool shell of the spool, andallowing the one or more metal rings to cool and shrink onto the cured shell:further comprising machining interfacial surfaces of the one or more metal rings after the positioning and before or after the curing. 17. The method as claimed in claim 16 further comprising applying one or more annular adhesive layers on the cured composite spool shell before sliding the heated one or more metal rings in place over the one or more annular adhesive layers.
