A hybrid torque box comprising a plurality of composite tubes and metal fittings attached together in alternating succession and configured to attach a thrust reverser to an engine fan case of an aircraft. The hybrid torque box may be substantially hollow and may comprise two V-blades for attaching the torque box to the engine fan case. The hybrid torque box may also be attached to or integral with a bull nose fairing configured for attachment with a cascade of the thrust reverser. Furthermore, the hybrid torque box may comprise and/or attach to a cowl interface flange configured for interfacing with an outer cowl of the thrust reverser.

1. A hybrid torque box comprising: a first composite tube having a first end and a second end;a first metal fitting having a first end and a second end, wherein the first end of the first metal fitting is mated with the second end of the first composite tube;a second composite tube having a first end and a second end, wherein the first end of the second composite tube is mated with the second end of the first metal fitting; andwherein, the hybrid torque box attaches to both an aircraft engine fan case and a thrust reverser. 2. The torque box of claim 1, wherein the first and second composite tubes are substantially curved and configured to match a curved shape of the thrust reverser. 3. The torque box of claim 1, wherein the first metal fitting is hollow and configured to house an actuator attached to portions of the thrust reverser and configured to slide said portions of the thrust reverser in a direction away from the torque box. 4. The torque box of claim 1, further comprising: a second metal fitting having a first end and a second end, wherein the first end of the second metal fitting is mated with the second end of the second composite tube; anda third composite tube having a first end and a second end, wherein the first end of the third composite tube is mated with the second end of the second metal fitting. 5. The torque box of claim 4, further comprising: a first metal V-blade fitting attached to the first composite tube; anda second metal V-blade fitting attached to the third composite tube. 6. The torque box of claim 4, wherein the first and third composite tubes are shorter in length than the second composite tube. 7. The torque box of claim 4, further comprising a bull nose fairing attached to or integral with at least one of the first, second, and third composite tubes and the first and second metal fittings, wherein the bull nose fairing is made of composite material and configured to attach to a cascade of a thrust reverser. 8. The torque box of claim 4, further comprising a fire-resistant material applied to or integral with at least one of the composite tubes and metal fittings. 9. A nacelle of an aircraft, the nacelle comprising: a thrust reverser comprising a first half and a second half;an engine fan case;a first hybrid torque box comprising: a first composite tube having a first end and a second end,a first metal fitting having a first end and a second end, wherein the first end of the first metal fitting is mated with the second end of the first composite tube, anda second composite tube having a first end and a second end, wherein the first end of the second composite tube is mated with the second end of the first metal fitting; anda second hybrid torque box comprising substantially identical components and configuration as the first hybrid torque box,wherein the first hybrid torque box is attached to the first half of the thrust reverser, the second hybrid torque box is attached to the second half of the thrust reverser, and both the first and second hybrid torque boxes are configured to be attached to the engine fan case. 10. The nacelle of claim 9, wherein at least one of the first and second hybrid torque boxes further comprises: a second metal fitting having a first end and a second end, wherein the first end of the second metal fitting is mated with the second end of the second composite tube; anda third composite tube having a first end and a second end, wherein the first end of the third composite tube is mated with the second end of the second metal fitting. 11. The nacelle of claim 9, further comprising at least one actuator, wherein the actuator is attached to a translating portion of the thrust reverser and configured to slide the translating portion in an aft direction away from the first or second hybrid torque box, wherein the first metal fitting is hollow and configured to house the actuator. 12. The nacelle of claim 10, wherein at least one of the first and second hybrid torque boxes further comprises: a first metal V-blade fitting attached to the first composite tube; anda second metal V-blade fitting attached to the third composite tube,wherein the first and second metal V-blade fittings interface with the engine fan case. 13. The nacelle of claim 10, wherein the first and third composite tubes are shorter in length than the second composite tube. 14. The nacelle of claim 10, further comprising a bull nose fairing attached to or integral with at least one of the first half and the second half of the torque box, wherein the bull nose fairing is made of composite material. 15. The nacelle of claim 14, wherein the thrust reverser is a cascade thrust reverser having at least one cascade, wherein the bull nose fairing is attached to the cascade. 16. The nacelle of claim 10, wherein each half of the thrust reverser further comprises: a hinge beam attached to the first end of the first composite tube of at least one of the first and second torque boxes; anda latch beam attached to the second end of the third composite tube of at least one of the first and second torque boxes.
