3. The tension management system of claim 1 , further comprising at least one pin configured to pass through one of the at least one cam port and into one of the at least one frame port.

4. The tension management system of claim 1 , further comprising at least one pulley block with at least one launching cord anchor for anchoring a launching cord.

5. The tension management system of claim 4 , further comprising a flexible tuning string at a length exceeding that of the launching cord, having a first end and a second end.

6. The tension management system of claim 4 , wherein the at least one launching cord anchor is a hook shaped anchor.

7. The tension management system of claim 1 , further comprising at least one pulley block with at least one hook shaped cable anchor.

8. A method of installing cables and a launching cord in a torsion spring and cam elastic energy storage and deployment counteracting block and tackle system, the method comprising:

connecting a first end of at least one cable to respective movable cable anchors on at least one cam;

connecting a second end of the at least one cable to a connection point on a pulley block;

moving the pulley block to tension the at least one cable;

aligning a cam port in each of the at least one cam to at least one frame port formed in a rigid frame supporting the at least one cam;

placing a pin through the aligned cam port and frame port;

installing the launching cord in the torsion spring and cam elastic energy storage and deployment counteracting block and tackle system.

9. The method of claim 8 , wherein:

the at least one cable includes a first cable, a second cable, a third cable and a fourth cable;

the at least one cam includes a first cam, a second cam, a third cam and a fourth cam;

the pulley block includes a first pulley block, attached to the second end of the first cable and the second cable, and a second pulley block, attached to the second end of the third cable and the fourth cable.

10. The method of claim 9 , further comprising connecting a flexible tuning string to unite the first pulley block and the second pulley block.

11. The method of claim 10 , further comprising tensioning the flexible tuning string to align the cam ports with the frame ports.

12. The method of claim 11 , further comprising:

relieving tension in the flexible tuning string; and

replacing the flexible tuning string with the launching cord.

13. The method of claim 8 , further comprising adjusting the movable cable anchors on each of the at least one cams to align the cam ports with the frame ports when the pulley block is moved to tension the at least one cable.

14. A method of using a torsion spring and cam elastic energy storage and deployment counteracting block and tackle system comprising:

transferring tension from cables and a launching cord to a ridged frame within the torsion spring and cam elastic energy storage and deployment counteracting block and tackle system by adding tension to the launching cord to position a cam port directly adjacent a frame port in the ridged frame, connecting a pin between the cam port and the frame port, and relieving tension in the launching cord.

15. The method of claim 14 , wherein:

the cables include a first cable having a first end attached to a first movable cable anchor of a first cam, a second cable having a first end attached to a second movable cable anchor of a second cam, a third cable having a first end attached to a third movable cable anchor of a third cam and a fourth cable having a first end attached to a fourth movable cable anchor of a fourth cam;

the first cable and the second cable each having a second end attached to a first pulley block; and

the third cable and the fourth cable each having a second end attached to a second pulley block.

16. The method of claim 15 , wherein:

a first cam port of the first cam and a second cam port of the second cam align with a first frame port in the rigid frame;

a third cam port in the third cam and a fourth cam port of the fourth cam align with a second frame port in the rigid frame; and

the pin includes a first pin and a second pin.

17. The method of claim 15 , further comprising:

moving at least one of the first, second, third and fourth movable cable anchors rearward to increase tension in at least one of the first, second, third and fourth cable, respectively; and

moving at least one of the first, second, third and fourth movable cable anchors forward to decrease tension in at least one of the first, second, third and fourth cable, respectively.

18. A method for adjusting tension in at least one of a cable and a launching cord within a torsion spring and cam elastic energy storage and deployment counteracting block and tackle system comprising:

extending a first cable between a first pulley block and a first movable cable anchor of a first cam;

moving the movable cable anchor rearward to increase tension; and

moving the movable cable anchor forward to decrease tension.

19. The method of claim 18 , wherein:

the at least one cable includes a first cable having a first end attached to a first movable cable anchor of a first cam, a second cable having a first end attached to a second movable cable anchor of a second cam, a third cable having a first end attached to a third movable cable anchor of a third cam and a fourth cable having a first end attached to a fourth movable cable anchor of a fourth cam;

the first cable and the second cable each having a second end attached to a first pulley block; and

the third cable and the fourth cable each having a second end attached to a second pulley block.

20. The method of claim 19 , further comprising:

adjusting tension of the first cable and the second cable to apply even force on the first pulley block; and

adjusting tension of the third cable and the fourth cable to apply even force on the second pulley block.
