| titleOfInvention | Improvements in or relating to a frangible aerial tow target |
| abstract | 810,138. Towed aerial targets. DEL MAR ENGINEERING LABORATORIES. May 28, 1956, No. 16493/56. Class 4. [Also in Group XL(c)] A frangible aerial towed target comprises a streamlined elongate rigid body member made of non-metallic material permeable by radar waves, reflector means carried internally of the body for reflecting externally propagated radar-waves, and stabilizing fan elements carried by the trailing portion of the body. In Fig. 1, the target is assembled from three sections 11, bonded at 12. Fins 25 are set in slots formed in the sections. All the pieces are moulded or machined from a foamed plastic, e.g. cellulose acetate or polystyrene, and bonded together. Strands of nylon cord 22 are anchored in the body and attached to releasable hooks 23 on a pylon 21 on the towing aircraft. A nylon cord 16 is formed into a coil 15 located in the target, one end 17 being anchored in the target and the other anchored at 24 to the pylon, whereby the cord is payed out under the drag of the target when released for towing. An electrical resistance element 31 may be energized to burn through the cord to disconnect the target. A radar wave reflecting element 26 comprises three discs 27 of corrugated paper laminated with aluminium foil, the discs meeting at right angles, and fitting into slots formed in the body. In Fig. 6, four elements 41 compose a nose section, and four elements 42 a tail section. All the elements fit onto a low strength radar reflector 48 and are bonded to the reflector and to each other. A fin assembly 44 made of balsa wood is bonded into slots 49 in the tail section. Fig. 9 shows a variant in which the target is made in three sections, each of four elements, and comprises two radar reflectors 61, 62. The fins comprise a pair 64 (one shown) at a positive dihedral angle and a single downwardly pointing fin 63. Lines 66 extend one from point 67 to point 68, and one from point 69 on fin 64 shown to a similar point on the fin 64 not shown. These lines reinforce the target, and a hook on a towing cable 65 engages one line. In Fig. 13, the body sections 111, 112, 113 and 114 are made of moulded impregnated paper pulp. Section 112 is joggled and flanged at 115, 116 and bonded to section 111, and sections 113, 114 are similarly connected. Sections 112 and 113 are bonded to a cylindrical face of a foamed plastic member 119 containing a radar reflector. The aft section 114 is reinforced at 134 by corrugated paper bulkheads. The fins 139 are of moulded foamed plastic, and the tip 144 of each is bent so that the target rotates in flight. The towing cable is attached to a swivel pin 147 at the nose mounted in a sleeve 148 attached to a plate 151. Sand 154 is retained between two plastic discs 153, 155 to make the target nose heavy. The fins may be formed of impregnated paper pulp reinforced by corrugated paper webs and paper honeycomb. |
