Abstract
Official abstract text for this publication.
A method for generating power in a gravity dropped munition, the method including: winding a cable around a drum of a generator associated with the munition; attaching the cable from the generator to a portion of an aircraft; separating the munition from the aircraft to unwind the cable from the drum to release the cable from the drum after a predetermined amount of rotation of the drum; converting the rotation of the drum to energy in a spring as the cable is unwound from the drum; restricting movement of an intermediate member connecting the drum to the generator while the cable is being unwound from the drum; and ending the restricting when the cable is released from the drum allowing the intermediate member to engage the drum with the generator to produce power from the generator.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for generating power in a gravity dropped munition, the method comprising: winding a cable around a drum of a generator associated with the munition; attaching the cable from the generator to a portion of an aircraft; separating the munition from the aircraft to unwind the cable from the drum to release the cable from the drum after a predetermined amount of rotation of the drum; converting the rotation of the drum to energy in a spring as the cable is unwound from the drum; restricting movement of an intermediate member connecting the drum to the generator while the cable is being unwound from the drum; and ending the restricting when the cable is released from the drum allowing the intermediate member to engage the drum with the generator to produce power from the generator. 2. The method of claim 1 , wherein the intermediate member is a first gear connecting the drum to a second gear at the generator. 3. The method of claim 1 , wherein the restricting comprises restricting rotation of the intermediate member in a same direction as an unwinding direction of the drum as the cable is unwound from the drum. 4. The method of claim 3 , wherein the restricting comprises permitting rotation of the intermediate member in a direction opposite to the same direction as the unwinding direction of the drum as the cable is unwound from the drum. 5. The method of claim 1 , wherein the restricting comprises routing the cable through a portion of the intermediate member to restrict all movement of the intermediate member as the cable is unwound from the drum. 6. The method of claim 1 , further comprising restricting a movement of the drum in a direction opposite to an unwinding direction as the cable is unwound from the drum. 7. The method of claim 6 , further comprising removing the restricting of the movement of the drum in the direction opposite to an unwinding direction after the cable is fully unwound from the drum.
