Abstract

A system having a damper with six or more indentations on alternating sides of the damper, where each indentation is open to an outer circumferential surface of the damper and extends over halfway through a width of the damper, and six or more slots, each slot open to an undulating inner circumferential surface of the damper and extending through the width of the damper.

Claims (26)

1. A system comprising:

a damper, the damper comprising:

two or more indentations on alternating faces of the damper, wherein each indentation is open to an outer circumferential surface of the damper;

a motor mount, the motor mount comprising two or more tabs, wherein the two or more tabs of the motor mount are seated in the two or more indentations of the damper; and

wherein an air space remains in each of the two or more indentations after the two or more tabs are seated in the two or more indentations of the damper for further compression of the damper against each of the two or more tabs.

2. The system of claim 1 , wherein a first plurality of indentations of the two or more indentations is on an upper surface of the damper.

3. The system of claim 2 , wherein a second plurality of indentations of the two or more indentations is on a lower surface of the damper.

4. The system of claim 3 , wherein the first plurality of indentations is alternatively arranged with indentations of the second plurality of indentations.

5. The system of claim 4 , wherein each indentation of the first plurality of indentations and the second plurality of indentations extends partially through a width of the outer circumferential surface of the damper.

6. The system of claim 4 , wherein the two or more indentations each do not extend entirely through a width of the outer circumferential surface of the damper.

7. The system of claim 1 , wherein the alternating faces of the damper are a front face of the damper and a rear face of the damper.

8. The system of claim 1 , wherein the two or more indentations each extend over halfway through a width of the outer circumferential surface of the damper.

9. The system of claim 1 , wherein the damper further comprises:

one or more slots.

10. The system of claim 9 , wherein each slot is open to an undulating inner circumferential surface of the damper.

11. The system of claim 9 , wherein each slot extends through a width of the damper.

12. The system of claim 9 , further comprising:

a motor, the motor comprising one or more fins disposed along an outer edge of the motor.

13. The system of claim 12 , wherein the one or more fins of the motor are seated in the one or more slots of the damper.

14. The system of claim 1 , wherein each of the two or more indentations has opposing indentation sidewalls with curved edges.

15. The system of claim 14 , wherein each of the curved edges of the opposing indentation sidewalls compress against each respective tab.

16. The system of claim 1 , wherein the two or more tabs of the motor mount are seated in the two or more indentations of the damper to self-encapsulate the outer circumferential surface of the damper in the motor mount.

17. The system of claim 1 , further comprising an aerial vehicle.

18. The system of claim 17 , wherein the motor mount is connected to the aerial vehicle.

19. The system of claim 17 , wherein the motor mount is connected to a fuselage of the aerial vehicle.

20. The system of claim 17 , wherein the aerial vehicle is an unmanned aerial vehicle (UAV).
