A fairing drive assembly couples a flap assembly of a wing of an aircraft to a fairing of the wing. The fairing drive assembly may include a fairing cam including a first joint and a second joint, and a flap link pivotally coupled to the first joint of the fairing cam and the flap assembly. A fairing drive arm is pivotally coupled to the second joint and the fairing. The fairing cam is configured to rotate upon actuation of the flap assembly and deflect the fairing away from the flap assembly.

1. A fairing drive assembly that is configured to couple a flap assembly of a wing of an aircraft to a fairing of the wing, the fairing drive assembly comprising: a fairing cam including a first joint a second joint, and a third joint, wherein the first joint and the second joint are separated by a first linear distance, wherein the first joint and the third joint are separated by a second linear distance, wherein the second joint and the third joint are separated by a third linear distance, and wherein the first linear distance is greater than each of the second linear distance and the third linear distance;a flap link pivotally coupled to the first joint of the fairing cam;a fairing drive arm pivotally coupled to the second joint, wherein the fairing drive arm is also configured to be pivotally coupled to the fairing; anda support brace pivotally coupled to the third joint and a flap support tension beam,wherein the fairing cam is configured to rotate upon actuation of the flap assembly and deflect the fairing away from the flap assembly. 2. The fairing drive assembly of claim 1, wherein the third joint is a cam central joint located proximate to an apex of a main body of the fairing cam. 3. The fairing drive assembly of claim 1, further comprising a flap link brace that is pivotally coupled to the first joint, and wherein the flap link brace is also configured to be pivotally coupled to a flap support tension beam. 4. The fairing drive assembly of claim 1, wherein the fairing drive assembly is devoid of a spring. 5. The fairing drive assembly of claim 1, wherein the fairing cam comprises a main body having a triangular shape. 6. The fairing drive assembly of claim 1, wherein the first joint is a cam crown joint. 7. The fairing drive assembly of claim 1, wherein the second joint is a cam fore joint. 8. A wing assembly of an aircraft, the wing assembly comprising: a fixed main body;a flap assembly moveably secured to the fixed main body between a retracted position and a fully-extended position;a fairing moveably secured to the fixed main body; anda fairing drive assembly coupling the flap assembly to the fairing, the fairing drive assembly comprising: a fairing cam including a first joint a second joint, and a third joint, wherein the first joint and the second joint are separated by a first linear distance, wherein the first joint and the third joint are separated by a second linear distance, wherein the second joint and the third joint are separated by a third linear distance, and wherein the first linear distance is greater than each of the second linear distance and the third linear distance;a flap link pivotally coupled to the first joint of the fairing cam;a fairing drive arm pivotally coupled to the second joint, wherein the fairing drive arm is also pivotally coupled to the fairing; anda support brace pivotally coupled to the third joint and a flap support tension beam,wherein the fairing cam is configured to rotate upon actuation of the flap assembly and deflect the fairing away from the flap assembly in response to the flap assembly moving from the retracted position towards the fully-extension position. 9. The wing assembly of claim 8, wherein the third joint comprises a cam central joint located proximate to an apex of a main body of the fairing cam. 10. The wing assembly of claim 8, further comprising a flap link brace that is pivotally coupled to the first joint, and wherein the flap link brace is also pivotally coupled to a flap support tension beam. 11. The wing assembly of claim 8, wherein the fairing drive assembly is devoid of a spring. 12. The wing assembly of claim 8, wherein the fairing cam comprises a main body having a triangular shape. 13. The wing assembly of claim 8, wherein the first joint is a cam crown joint. 14. The wing assembly of claim 8, wherein the second joint is a cam fore joint. 15. The wing assembly of claim 8, wherein the flap assembly comprises at least two flaps. 16. The wing assembly of claim 8, further comprising an actuation system secured to a fixed structure within the wing, wherein the actuation system is coupled to the flap assembly, and wherein the actuation system is configured to actuate the flap assembly between the retracted position and the fully-extended position. 17. A wing assembly of an aircraft, the wing assembly comprising: a fixed main body;a flap assembly moveably secured to the fixed main body between a retracted position and a fully-extended position, wherein the flap assembly comprises at least two flaps;an actuation system secured to a fixed structure within the wing, wherein the actuation system is coupled to the flap assembly, wherein the actuation system is configured to actuate the flap assembly between the retracted position and the fully-extended position;a fairing moveably secured to the fixed main body; anda fairing drive assembly that is devoid of a spring and couples the flap assembly to the fairing, the fairing drive assembly comprising: a fairing cam comprising a main body having a triangular shape, wherein the main body includes a first joint, a second joint, and a third joint;a flap link pivotally coupled to the first joint of the fairing cam;a fairing drive arm pivotally coupled to the second joint, wherein the fairing drive arm is also pivotally coupled to the fairing;a support brace pivotally coupled to the third joint, and wherein the support brace is also pivotally coupled to a flap support tension beam of a flap support structure extending from the fixed main body of the wing; anda flap link brace that is pivotally coupled to the first joint, and wherein the flap link brace is also pivotally coupled to the flap support tension beam,wherein the fairing cam is configured to rotate upon actuation of the flap assembly and deflect the fairing away from the flap assembly in response to the flap assembly moving from the retracted position towards the fully-extension position. 18. The wing assembly of claim 17, wherein the first joint comprises a cam crown joint, wherein the second joint comprises a cam fore joint, and wherein the third joint comprises a cam central joint located proximate to an apex of a main body of the fairing cam.
