758,334. Finned projectiles. ROBERT. R. A.. and MATGE. P. P. Dec. 30. 1954 [Jan. 4. 1954], No. 37628/54. Classes 9(1) and 9(2) Rocket bombs are arranged horizontally one above the other in a vertical row each bomb being supported by the bomb above and the uppermost bomb by a support, the support means being also a guide and the support and guide means being part of the fin structure of the bombs. The rocket body 10 has an annular flange 11 from which project bosses 12 in which are secured rods 13 arranged longitudinally of the rocket and carrying fins A<SP>1</SP>, A<SP>2</SP> . A<SP>3</SP>, A<SP>4</SP>. Springs 44 surrounding rods 37 aligned or integral with rods 13 bear against bosses 22 which receive the rods 37 and 13 and against sockets 38 bv which the rear end of each fin is pivoted on rod 37. Each boss 22 has a cut-away part 27 co-operating with a tongue 28 of an enlarged part 20 of the associated fin to lock the fin in the expanded position. The enlarged part 20 of fins A<SP>1</SP>, A<SP>2</SP> is forked to form two legs 33, 34 which when the fins are in the collapsed position of Fig. 2 engage ribs 42<SP>3</SP>, 42<SP>4</SP> of circular section on the inner edge of the fins A<SP>3</SP>, A<SP>4</SP> of a rocket B<SP>1</SP> immediately above rocket B, Fig. 2. In the expanded position, the fins are pressed against abutment stops 15, Fig. 11, by their associated springs. To fold the fins, they are pushed forwardly disengaging the tongues 28 from their respective notches and compressing the springs 44. Fins A<SP>3</SP>, A<SP>4</SP> are then pivoted to abut against stops 15, 15 and subsequently fins A<SP>1</SP>, A<SP>2</SP> are folded over fins A<SP>3</SP>, A<SP>4</SP>, the forked parts of fins A<SP>1</SP>, A' then being uppermost ready for engagement with the ribs 42 of another rocket. Forwardly the rockets B, B<SP>1</SP> may be. secured together as in Specification 724,781. The rockets are stored in an aircraft magazine in vertical rows, the uppermost rocket in each row being suspended from a support having ribs similar to the ribs 42 for engagement with the fins of the rocket. As the rocket is fired, it moves forward guided by the ribs 42 of the rocket above, until the fins leave the ribs. Whereupon the fins are forced to expand by the springs 44, until halted bv the stops 15. The fins then set back until tongues 28 enter the notches 27 locking the fins in position. The propellant gases of the rocket escape through a nozle 50 having a frustoconical section 51, a cylindrical part 52 and a divergent outlet 53. The nozzle 50 may be used as a core on which to mould the sleeve 23 supporting the fins.
