1. A chaff dispersion apparatus having a substantially cylindrical rocket dispensing head adapted to be fired from an aircraft, the improvement iN said dispensing head comprising a main body portion, a nose cone mounted on the forward end of said main body portion and variable firing means mounted at the rearward end thereof, a plurality of sections in said rocket head located intermediate said nose cone and said firing means, a plurality of equally spaced partitions mounted perpendicularly on said main body portion forming said sections, a frangible container enclosing each section, chaff stacked in orderly rows within said containers, an explosive charge within each container mounted on the axis of said main body portion to insure that the forces of the explosive are applied to the chaff in a radial direction and said variable firing means progressively exploding said charges after said rocket head has been fired from the aircraft whereby said frangible containers are destroyed, the chaff dispersed in a radial direction and the rocket head is left intact after each explosion to continue its flight.
2. An apparatus as claimed in claim 1 wherein the rocket head has a single row of sections in end to end relationship.
3. An apparatus as claimed in claim 1 wherein the rocket head has a plurality of rows of sections radially arranged around the central axis of said rocket head.
4. A chaff dispersing apparatus adapted for firing from an aircraft comprising a longitudinal support member, a nose cone mounted on one end of said support, a rocket fuel compartment mounted on the other end of said support, a plurality of disc shaped members mounted on and traversing said support in a perpendicular manner so that the area between the nose cone and the rocket compartment along said support is divided into a plurality of chambers, an explosive container in each chamber mounted through said support and adapted to receive a bolt from each end projecting through said support, chaff packed in each chamber around the explosive container, a pair of semi-cylindrical frangible shells closing each chamber, a frangible bolt secured in an end of said explosive container to hold each semi-cylindrical shell in place, and a means for firing said explosive containers at predetermined intervals so that said bolt and said semi-cylindrical shells are ruptured allowing the explosive force to disperse the chaff into the air.
5. An apparatus as claimed in claim 4 wherein said means for firing the explosive containers at predetermined intervals comprises a continuous pyrotechnic fuze passing through each explosive container and which is initially ignited by the burning of the rocket fuel in said rocket fuel compartment.
6. An apparatus as claimed in claim 4 wherein said means for firing the explosive containers at predetermined intervals comprises an electronic circuit.
7. An apparatus as claimed in claim 6 wherein said electronic circuit is a first capacitor connected across a direct current voltage source, a second capacitor operatively associated with said first capacitor, a first pressure switch operatively connected between said first and second capacitors, said first pressure switch having a first position connecting said first and second capacitors in series and having a second position opening the circuit between said first and second capacitors, a third capacitor operatively associated with said second capacitor, a second pressure switch operatively connected between said second and third capacitors, said second pressure switch having a first position opening the circuit between said second and third capacitors and connecting said third capacitor to ground and having a second position connecting said second and third capacitors is series, a squib connected across said first capacitor, said first and second pressure switches operatively positioned with relationship to said squib, said first and second switches being in their first positions when said squib is unfired, said first and second pressure switches being changed to their second positions upon the firing of said squib, a cold cathode diode connected acroSs said third capacitor, said explosive containers being operatively associated with said diode, a first of said explosive containers being connected in series with said diode, the remainder of said explosive containers each having a frangible flap switch operatively associated therewith, each frangible flap switch having a first position opening the circuit between its respective explosive container and said diode and having a second position closing the circuit between its respective explosive container and said diode, said first explosive container upon explosion closing a first of said frangible flap switches, the remainder of said frangible flap switches and said explosive containers except the last explosive container operating in the same manner as said first frangible flap switch and said first explosive container.
8. A chaff dispensing apparatus comprising a longitudinal support member having a forward and an after end, division members mounted on and traversing said support for forming a plurality of chambers along said support member, a frangible shell enclosing each chamber, explosive means mounted within each chamber, said explosive means consisting of an explosive charge within a container that is perpendicularly mounted in a bore within said support means and projecting radially therefrom to said frangible shell, a frangible securing means for securing each frangible shell to said support, said frangible securing means extending through said shell and fixedly secured to the outer ends of said explosive container, chaff packed in each chamber around the explosive container, and firing means for firing said explosive means at predetermined intervals.
9. A chaff dispersing apparatus as claimed in claim 8 wherein each frangible shell is cylindrical in shape and is divided into two parts.
10. A chaff dispersing apparatus as claimed in claim 9 wherein said firing means includes a continuous pyrotechnic fuze passing through each explosive container and further includes igniting means for igniting said pyrotechnic fuze.
