GRAVITY DROPPED MUNITION HAVING ENERGY HARVESTING DEVICE FOR POWER GENERATION ONBOARD MUNITION
First Claim
1. A munition comprising:
- a shell; and
a generator comprising;
a drum having a cable wound thereon, the cable having a free end, wherein the drum includes a drum gear which turns with the drum, the cable being releasable from the drum after being unwound from the drum;
a spring for storing energy as the cable is unwound from the drum by pulling on the free end;
an electromagnetic generator operatively connected to the drum such that rotation of the drum is transferred to an input side of the electromagnetic generator after the cable is unwound from the drum and the stored energy in the spring turns the member, wherein the electromagnetic generator includes a generator input gear on the input side at least indirectly connected to the drum gear; and
a clutch having a clutch input gear engaged with the drum gear and a clutch output gear engaged with the generator input gear, wherein the clutch is configured to transfer rotation of the clutch input gear to rotation of the clutch output gear after the cable is unwound and released from the drum and the stored energy in the spring turns the drum.
