3. The dispensing unit of claim 2 wherein the aperture is at a location offset from the first axis of the first end cap such that when material roving is drawn through the aperture by a tensile force, a rotational force is applied by the material roving to a corresponding material bundle.
4. The dispensing unit of claim 1 , wherein the first end cap has a first axis parallel to the central axis of the second end cap.
5. The dispensing unit of claim 1 , wherein the first end cap has a first end cap bore for rotatably engaging with the support rod.
6. The dispensing unit of claim 1 , wherein the second end cap has a second end cap bore for rotatably engaging the support rod.
7. The dispensing unit of claim 1 , wherein the at least one canister further comprises a plurality of canisters.
8. The dispensing unit of claim 7 , wherein the rack members comprise an associated plurality of bores for receiving the plurality of canisters, the plurality of bores arranged radially in a rack with a central angle of less than 180 degrees.
9. The dispensing unit of claim 8 , wherein the associated plurality of bores further comprises a central bore.
10. The dispensing unit of claim 1 , wherein the cavity is dimensioned to hold a plurality of countermeasure bundles.
11. The dispensing unit of claim 1 , wherein the canister cavity is repeatably accessible through the first end cap or the second end cap for loading the at least one material bundle into the canister cavity.
12. A material dispensing system for dispensing countermeasure roving from an airplane, comprising:
a material dispensing unit comprising at least one canister, each canister comprising:
a first end cap;
a second end cap having a central axis extending to the first end cap;
a support rod including a portion extending between the first end cap and the second end cap along the central axis, the support rod rotatably engaged with the first end cap;
a wall extending circumferentially about the support rod from the first end cap to the second end cap and defining a cavity for housing at least one countermeasure elongated parallel to the central axis;
an aperture defined by the first end cap and having an aperture central axis normal to the aperture, the aperture sized for dispensing countermeasure roving from the at least one countermeasure bundle; and
a first rack member including a first bore and a second rack member including a second bore, the first rack member and second rack member configured for attachment to a support structure to support the at least one canister such that: the at least one canister extends through the first rack member via the first bore and the second rack member via the second bore;
and the rod is oriented substantially parallel to the support structure; and
a material cutting unit operably engaged with the dispensing unit so as to: draw at least one countermeasure roving therefrom; cut the at least one countermeasure roving; and provide the at least one cut countermeasure roving to guide walls of the material cutting unit for directing the at least one cut countermeasure roving out of the airplane.
13. The material dispensing system of claim 12 , wherein the material cutting unit comprises:
a cutter roller disposed to rotate about a cutter roller axis and having a plurality of blades disposed across a surface of the cutter roller;
a platen roller disposed adjacent to the cutter roller to rotate about a platen roller axis and to have a surface in momentary contact with each of the one or more blades of the cutter roller; and
a drive structure providing motive force for rotating either or both of the cutter roller and the platen roller so as to draw at least one countermeasure roving between the cutter roller and the platen roller.
14. The material dispensing system of claim 13 , wherein the motive forces drive the cutter roller and platen roller such that the countermeasure roving is cut into desired lengths.
15. The material dispensing system of claim 12 , further comprising a drive structure operably engaged with each support rod of each of the at least one dispensing unit to controllably turn each support rod.
16. The material dispensing system of claim 12 wherein:
the support structure is configured for attachment to a support surface of the airplane.
17. The material dispensing system of claim 16 , wherein the material cutting unit further comprises:
guide walls; and
a platen roller and an adjacent cutter roller configured to draw the at least one countermeasure roving from the dispensing unit, cut the at least one countermeasure roving, and provide the at least one cut countermeasure roving to guide walls,
wherein the guide walls configured to direct the chopped countermeasure out of the material dispensing system.
18. A dispensing unit for dispensing material roving from an airplane, comprising:
a first rack member including a first bore;
a second rack member spaced a distance from the first rack member and including a second bore;
at least one canister extending along a central axis running orthogonally to the first rack member and second rack member, the at least one canister extending through the first rack member via the first bore and the second rack member via the second bore, each canister comprising:
