referring now to fig1 , the carriage and release system 10 is shown in dual configuration mounted on the left and right wings of a remotely piloted aircraft 12 . the carriage and release system 10 can , of course , be connected to any portion of the aircraft , including the wings , fuselage 14 , or any other appendage of the aircraft . the carriage and release system as shown in fig1 includes a pylon 16 attached to a bracket 17 , which in turn is affixed to the wings of the aircraft 12 . affixed to the bottom of the pylon 16 is a subcarriage 18 , which is one of a variety of subcarriages that may be attached to the pylon 16 . the carriage and release system 10 , as shown in fig2 , includes the pylon 16 and the bracket 17 . the bracket 17 has an upper surface 20 that is either flat or can be conformed to the surface to which it is to be mounted . if flat , and the surface to which it is to be mounted is curved , a variety of spacers ( not shown ) can be utilized to make the attachments . the bracket 17 is attached to the aircraft , whether it is the wing or fuselage , with conventional fasteners that extend through a plurality of apertures 22 that can be positioned in the bracket 17 at any of a variety of locations suitable to one of ordinary skill . the pylon 16 is pivotally attached to the bracket via arm 24 and transverse pivot pin 26 , which will be described in more detail below . the pylon 16 comprises a main body 30 that extends fore and aft or in the longitudinal direction . arms 32 extend downwardly from the front and back portions of the body 30 . the arms and body 30 are preferably integrally formed ; however , they can be formed of separate components if desired . the pylon 16 defines a mounting port 34 in both forward and rearward arms 32 having a cylindrical interior . the mounting port 34 in the forward arm and the rearward arm are axially aligned in the fore and aft direction . the bottom of each of the arms 32 carries a longitudinal slot 36 that extends all the way through the bottoms of the forward and rearward arms . the arms 32 are made of a flexible but resilient material so that the bottom of the arms can be pinched together so as to slightly decrease the diameter of the mounting ports to securely fasten a stores carrier therein , as will be described in more detail below . in addition , the bottom of the arms each have a longitudinal t - shaped slot 40 , again aligned in the fore and aft direction . the bottom of the slot opens downwardly from the arms 32 . the purpose of the slot 40 will be described in more detail below . referring now to fig3 a and 3b , the bracket 17 is shown mounted to an aircraft structure ( shown in phantom ). the pylon 16 depends from the bracket 17 via pivot pin 26 which extends transversely through arm 24 of the pylon . the downwardly extending arm 24 is affixed at its upper end to the bottom side of the bracket 17 . the pylon is journaled on the pivot pin 26 ; thus , the pylon 16 can pivot about the pivot pin 26 . because the arm is mounted in the fore and aft direction on the aircraft , this pivotal movement of the pylon 16 adjusts the pitch of the pylon relative to the aircraft ; thus , the aircraft can be flying in a horizontal mode while the pylon can be pivoted either upwardly or downwardly to pitch the pylon downwardly or upwardly so as to point the stores mounted on the pylon 16 in a downward or upward direction relative to the aircraft . in one embodiment , the pivotal movement of the pylon is driven by a power mechanism . in a preferred embodiment , the pivotal movement of the pylon is powered by a pair of jack screws 46 . the upper ends of the jack screws 46 are pivotally mounted to the underside of the bracket 17 via downwardly depending bracket 48 and pivot pin 50 . the jack screws 46 carry external threads that mate with internal threads on gear members 52 , which are journaled in the upper portion of the pylon 16 and spaced fore and aft from the pivot arms 24 . gear members 52 have integral pulleys 54 that are coupled together by an endless belt 56 so that when one gear member is rotated , both gear members 52 will rotate simultaneously with each other . the lower portion of the gear members 52 contains vertical splines or gear teeth 58 . in this embodiment , a shaft 60 containing a worm gear 64 at its end engages the splines 58 on the rear gear member 52 . as the worm gear 60 is rotated , the rear gear member 52 is rotated . the forward gear member 52 , which is slaved to the rear gear member by the pulleys 54 and belt 56 , rotates as the rear gear member is rotated . the worm gear 64 is driven by a motor 62 mounted in the pylon and powered from an external source ( not shown ). the jack screws 46 are counterthreaded so that as the gear members 52 rotate , the aft jack screw will move in a vertical direction opposite from the forward jack screw 46 . thus , as the jack screws move in opposite vertical directions , they will simultaneously work together to pivot the pylon 16 about the pivot pin 26 . one embodiment of a stores carrier 66 is illustrated in fig4 . stores carrier 66 is inserted in the mounting port 34 of the pylon 16 from the rear . stores carrier 66 has a rear shoulder 67 that abuts against the rear of the pylon 16 to index it in place . in this embodiment , the stores carrier has a plurality of axial channels 68 that run the entire length of the stores carrier . the axial channels 68 may carry flares , rockets , or other self - powered stores that can be fired from the stores carrier 66 . in fig5 , the stores carrier 66 is shown mounted in the pylon 16 . as can be seen , it extends from the rear arm 32 forwardly to the forward arm 32 of the pylon 16 . the stores carrier 66 is held firmly in place in the pylon 16 by the co - action of cam mechanisms 70 mounted on the bottom of the arms 32 of the pylon 16 . as the cam mechanism 70 is rotated , it causes the bottom end of the arms to be pinched together so that the slot 36 is made smaller , thus reducing the diameter of the chamber mounting port 34 and firmly clamping the stores carrier 66 in place . referring now to fig6 and 7 , a carrier subassembly 74 is shown for mounting a different type of store on the bottom of the pylon 16 . the subassembly 74 has a stores carrier 76 , which in this embodiment has a plurality of longitudinal bores that carry self - launched stores 78 . the upper portion of the subassembly 74 carries a rail 80 having an inverse - t configuration that fits in the slots 40 in the bottom of the arms 32 of the pylon 16 . the slot 40 has outwardly extending slot portions 40 a that terminate in bottom inwardly - directed shoulders 40 b . rail 80 has outwardly directed flanges 80 a that fit within the slots 40 so as to slidably position the subassembly 74 under the pylon . depending on the weight distribution of the subassembly 74 , it can be moved fore and aft , as desired , in the slots 40 . once the subassembly 74 is positioned on the pylon , the same cam mechanism 70 that holds a stores carrier in place in the pylon also clamps the slots 40 together to place a friction grip on the rail 80 and , thus , secures the subassembly 74 at the desired location . still referring to fig7 , the cam mechanism 70 comprises the shaft 90 that extends transversely through the arm 32 and threads into head 92 on one side of the arm 32 . the other end of the shaft 90 is threaded into a nut 94 having a lever arm 96 attached thereto . when the rail 80 is in place in the slot 40 , the shaft 90 is snugged down by rotating the head 92 until finger - tight . then the arm 96 is rotated to tighten the nut 94 beyond finger - tension - tight so that a secure friction grip is held not only on the rail 80 , but any stores carrier mounted in the port 34 . a similar cam mechanism 70 is also integrated into the rearward arm 32 of the pylon 16 . referring now to fig8 , another type of subcarriage assembly 100 is illustrated . this subcarriage assembly 100 has three mounting ports 102 , 104 , and 106 , in each of which is mounted a stores carrier 108 , 110 , or 112 . as depicted , the stores and stores carrier may be different for each of the ports of the subcarriage 100 . subcarriage assembly 100 has rails 114 on its upper side that can be coupled directly to the slots in the bottom of the pylon 16 . in addition , if desired , this subcarriage 100 can also carry a slotted member 116 on the bottom thereof so that another subcarriage assembly can be similarly mounted to the bottom of this subcarriage . the carriers 108 , 110 , and 112 are secured in the mounting ports 102 , 104 , and 106 by the cam mechanisms 120 on both the fore and aft depending arms of the subcarriage 100 . each of the arms carries a longitudinal slot extending along its entire length below each of the mounting ports . the cam mechanisms 120 pull the bottoms of the arms together to decrease the width of the slot and , thus , securely grip the stores in each of the mounting ports . the stores carrier 108 shown in fig8 includes an ejection mechanism shown in the exploded view in fig9 . the ejection mechanism is designed to eject the store 130 from the carrier 108 . the store 130 is the type that is not self - propelled and , thus , is forcibly ejected from the stores carrier 108 . the ejection mechanism 132 is shown in exploded view in fig9 . it includes an ejection plate 134 , a coil spring 136 , a detent retaining mechanism 138 , a backing plate 140 , a retaining plate 142 for the detent mechanism 138 , and a cocking cylinder 144 . referring now to fig9 and 10a , the rearward end of the carrier 108 has two longitudinal slots 146 , which run from the rearward end forwardly . these two slots are diametrically opposed from each other . the ejection plate 134 carries two diametric tabs 134 a that extend outwardly through the slots 146 . the backing plate 140 is secured on the rear end of the store 130 by suitable fasteners ( not shown ). the coil spring 136 is positioned between the backing plate 140 and the ejection plate 134 . the backing plate carries a central concentric cylindrical shell that extends forwardly from the central rear side of the backing plate 140 . a detent retaining mechanism 138 is positioned in the cylindrical shell of the backing plate 140 . a ball detent mechanism 138 a extends forwardly through an opening in the forward end of the cylindrical shell of the backing plate 140 . the ball detent mechanism is of a conventional design where a plurality of ball bearings are positioned to radially extend outwardly from a series of radial slots in the extension 138 a . ejection plate 134 carries a rearwardly extending cylindrical member 134 b having a rearward end with inwardly extending shoulder 134 c . the inner diameter of the shoulder 134 c is slightly larger than the outer diameter of the detent mechanism 138 a and is axially aligned therewith . the cocking cylinder 144 comprises a cylindrical shell having a rear plate with a lug 150 thereon . the inner surface of the cocking cylinder 144 carries internal threads . the internal diameter of the cocking cylinder is slightly larger than the external diameter of the stores carrier 108 . in use , the cocking cylinder is fitted over the rearward end of the carrier 108 until the internal threads in the cocking cylinder engage the external threads on the tabs 134 a of the ejection plate 134 . a suitable tool ( not shown ) is then affixed to the lug 150 and the cocking cylinder is rotated , for example , in a clockwise direction . the co - action of the internal threads in the cocking cylinder and the external threads on the tabs 134 a serve to move the ejection plate rearwardly toward the detent mechanism against the bias of the spring 136 . the cocking cylinder is rotated , as shown in fig1 b and 10c , until , as shown in fig1 d , the cylindrical member 134 b on the ejection plate 134 engages and moves past the forward end of the detent mechanism 138 a . the detent mechanism 138 a is then activated so that the balls extend outwardly from the radial ports therein . the shoulder 134 c then engages the balls to prevent the ejection plate from moving in a forward direction against the bias of spring 136 . the cocking cylinder 144 is then turned in the opposite direction to unthread it from the threaded tabs 134 a , thus removing the cocking cylinder from the stores carrier . the detent retaining mechanism contains an internal solenoid that expands the balls out of the radial apertures . this solenoid can be spring - loaded to keep it in place until activated by an external source . when the solenoid is activated by an external source , the balls in the detent device retract inwardly , releasing the ejection plate and causing the store 130 to be ejected from the stores carrier 108 . to retain the store 130 in the carrier 108 after the ejection mechanism has been cocked , and to provide electrical connections to the store 130 from the parent aircraft 14 , a radially extending electrical connector male end 160 is provided on the outer surface of the store 130 toward its rearward end or anywhere along its length . this connector 160 travels in a longitudinal channel 162 provided in the external surface of the store carrier 108 . an open slot 164 is provided at the rear end of the store so that when the store is in place against the cocked ejection plate 134 , the connector 160 is exposed . an electrical connector female end 166 is then positioned over the electrical connector male end 160 to provide electrical connectivity and to temporarily retain the store in place and prevent it from slipping out axially , should the carrier 108 be tipped in a downward and forward direction . the friction fit of the connector female end 166 over the connector male end 160 , however , is such that when the ejection mechanism is released and the plate 134 urges the store forward , the connector 166 rides upwardly on a pair of ramps 168 provided forward of the connector 166 , thus prying the connector female end 166 from the connector male end 160 and allowing the store to move forwardly and out of the carriage 108 . a safety pin 170 is also provided to prevent the ejection mechanism from operating prematurely . the pin is inserted in a diametric bore 172 in the carrier 108 . the bore 172 is situated just forward of the ejection plate when in a cocked position . when the carrier 108 is loaded in the subcarriage assembly and the aircraft is ready to deploy , the pin 170 may be removed to ready the ejection mechanism . while illustrative embodiments have been illustrated and described , it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention .
