Projectile Launching Systems with Anchors having Dissimilar Flight Characteristics

Abstract

A projectile deployment system includes a projectile casing having a pair of sockets, each socket sized to carry one of a pair of anchors of an entangling projectile having a tether connecting the pair of anchors. A pair of independently activable pressure sources are each capable of generating a pressure wave capable of expelling one of the anchors from one of the sockets to deploy the entangling projectile from the projectile casing toward a subject. At least one controller is operable to activate one or both of the pressure sources. Each pressure source is independently activatable at differing times so as to deploy the anchors from the projectile casing at differing times.

1 . A projectile deployment system, comprising:
 an entangling projectile, including a pair of anchors and a tether connecting the anchors; and   a projectile casing, including:
 a pair of sockets, each socket sized to carry one of the pair of anchors; 
 at least one pressure source, the pressure source being capable of expelling one or both of the anchors from the projectile casing toward a subject; 
   at least one of the entangling projectile or the projectile casing being configured such that the pair of anchors travel toward the subject with differing flight characteristics after being deployed from the projectile casing;   the flight characteristics including one or more of: a velocity of one of the anchors, a relative forward position of one of the anchors as it is discharged from a cartridge, an angle of trajectory relative to the projectile casing, an aerodynamic drag of one of the anchors, an aerodynamic drag of a portion of one of the projectiles that affects a velocity of the anchor, and an aerodynamic drag of a portion of the tether that affects a velocity of one of the anchors.   
     
     
         2 . The system of  claim 1 , wherein the pair of anchors differ from one another in at least one of: a material; a volume; a shape; a surface finish; a mass; an outer diameter and a drag coefficient. 
     
     
         3 . The system of  claim 1 , wherein the anchors are positioned in the sockets at differing forward positions relative to a front of the projectile casing. 
     
     
         4 . The system of  claim 1 , wherein each socket is fluidly coupled to an associated pressure source, and wherein a fluid resistance within one socket varies with respect to a fluid resistance within the other socket. 
     
     
         5 . The system of  claim 1 , wherein each socket is fluidly coupled to an associated pressure source, and wherein a power output of each pressure source differs. 
     
     
         6 . The system of  claim 1 , wherein each socket is fluidly coupled to an associated pressure source, and wherein the pressure sources are independently activatable at differing times. 
     
     
         7 . The system of  claim 1 , wherein the pair of anchors have matching outer diameters and wherein the pair of sockets have differing inner diameters. 
     
     
         8 . The system of  claim 1 , wherein the pair of sockets have differing inner diameter surface finishes. 
     
     
         9 . The system of  claim 1 , wherein a section of the tether adjacent each of the pair of anchors differs in one of: a relative position, a weight, a surface finish or a drag coefficient. 
     
     
         10 . A projectile deployment system, comprising:
 a projectile casing, including:
 a pair of sockets, each socket sized to carry one of a pair of anchors of an entangling projectile having a tether connecting the pair of anchors; 
   a pair of independently activable pressure sources, each pressure source being capable of generating a pressure wave capable of expelling one of the anchors from one of the sockets to deploy the entangling projectile from the projectile casing toward a subject; and   at least one controller, operable to activate one or both of the pressure sources;   each pressure source being independently activatable at differing times so as to deploy the anchors from the projectile casing at differing times.   
     
     
         11 . A method of deploying an entangling projectile carried by an entangling projectile launcher, the entangling projectile launcher including a pair of sockets, with one each of a pair of anchors carried in each socket and a tether connecting the anchors, the method comprising:
 initiating a pair of pressure sources at differing times to thereby propel each of the anchors forwardly within each respective socket such that the pair of anchors are deployed from the launcher at differing times.
