Abstract

A method for generating power in a gravity dropped munition. The method including: attaching a cable from a generator associated with the munition to a portion of an aircraft; separating the munition from the aircraft to pull the cable from the munition; converting the pulling of the cable to a rotation; producing power from the rotation; and providing the power to an internal component of the munition.

Claims

1. A method for generating power in a gravity dropped munition, the method comprising:

attaching a cable from a generator associated with the munition to a portion of an aircraft;

separating the munition from the aircraft to pull the cable from the munition;

converting the pulling of the cable to a rotation;

producing power from the rotation; and

providing the power to an internal component of the munition.

2. The method of claim 1, further comprising:

sensing an air velocity at the munition for distinguishing separation of the munition from the portion of the aircraft while in flight from another event in which power from the generator is not desired; and

controlling the generator output based on an output of the air velocity sensor.
