8 cm Raketen Sprenggranate: H.E. Unrotated Rocket

8 cm Raketen Sprenggranate: H.E. Unrotated Rocket

This rocket is actually 78 mm in diameter. Two features distinguish it from other German rockets: the use of tail fins to secure stability in flight without rotation, and the employment of a novel fuze arming device.

The complete round weighs 15.19 pounds and is nearly 28 inches long. Its two principal components are the nose fuzed high explosive war head and the rocket motor tube. The shell is attached by means of an adaptor ring and the motor tube is closed by a cone-shaped assembly carrying the fins and containing the venturi and propellant supporting grid. Six tubular sticks of cordite form the propellant ignited by a circular gun powder igniter set off by a wire ignition bridge. The launcher used is the Mantelrohr.

The nose fuze consists of a steel nose piece housing a light alloy striker held by a light spring, a percussion detonator, a magazine containing four pressed pellets, and a thermal arming device. When the rocket is fired, the heat of the propellant gases melts a ring of fusable metal, permitting the detonator and magazine to approach the striker. The main filling of the high explosive head is pressed flake TNT.

8.8 cm R. Pz. B. Gr. 4312: Antitank Rocket Grenade

German 8.8 cm R. Pz. B. Gr. 4312: Antitank Rocket Grenade

This projectile is fired from the German 8.8 cm Raketenwerfer 43 (Püppchen—see page 352.1). From this weapon, as limited by the sight, a maximum effective range of 700 meters (765 yards) is obtained. The explosive head is identical to that of the rocket fired from the German counterpart of the “Bazooka” (page 357).

The fuze (AZ 5095) functions as follows: the force of set back causes the set-back ring to move rearward, bending the two prongs of the stirrup spring. These prongs, by engaging in the inside groove of the set-back ring prevent the ring from returning forward. Meanwhile, the striker needle is held away from the primer detonator by a flat, coiled clock spring inside the set-back ring. The clock spring unwinds, expanding against the inside of the fuze body, thus providing a slight delay in the arming of the fuze.

The propellant is a double base powder in the form of a single grain with 14 perforations. There is a hole .364 inch in diameter through the center of the grain. Three lands on the outside of the grain insure an outside burning surface. A triangular-shaped spacer holds the head igniter firmly against the quickmatch. The quickmatch fits in a slight indentation in the head igniter. The primer used in the “Püppchen” rocket is the standard No. 26 percussion primer found in many German artillery fuzes.

30 cm Wurfkörper 42 Spreng: 30 cm Rocket

30 cm Wurfkörper 42 Spreng: 30 cm Rocket

This rocket is packed in a wooden crate from which it may be fired in the same manner as the 28 cm rocket described on page 354. It is also fired from a rocket projector consisting of six welded metal frames mounted on a two-wheeled, split trailed carriage described on page 350.

This model has been selected to illustrate the construction of the motor assembly of a typical rotating rocket. The motor tube is 0.43 inch thick, closed at one end, and threaded inside to take the venturi block. Eighteen venturis are drilled in this solid block. The throat diameter of each venturi is 0.365 inch with an exit section of approximately 0.82 inch in diameter. The axes of the venturis are inclined at an angle of 12° 42′ so that the effluent gases cause the round to rotate. A threaded hole in the center takes the primer unit.

Seven tubular sticks make up the propellant charge composed of nitrocellulose and diglycol dinitrate.

German 30 cm Rocket

The sticks are supported at the venturi end on a grid. The center stick contains a length of quickmatch in a celluloid tube, and ending in a primed maintainer pellet. A small primer unit screwed into the steel venturi plug flashes directly on to the gun powder pellet at the end of the celluloid tube.

This motor unit is similar to that of the 15 cm Wurfgranate. However, because of the heavier charge in the 30 cm ammunition, the metal mesh has been introduced to prevent the maintainer pellet from being crushed by the central stick of the propellant charge if the rocket is dropped.

Fallschirm Leuchtpatrone für Kampfpistole: Illuminating Star on Parachute: Miscellaneous Pistol Grenades

Fallschirm Leuchtpatrone für KampfpistoleThis type grenade has the same general contours as the two others previously described. It has a black bakelite head and a screwed-on base plug which is perforated to hold a gunpowder pellet. Inside the grenade, directly above the plug is an illuminating star to which a parachute is attached. On firing, the flash from the propellant ignites the gunpowder pellet, which, after a brief delay, ignites the star. The bakelite head is blown off, and the star ejected. The grenade may be identified by the stencilling “F. Leucht. Z.” on the base of the cartridge case.

Deutpatrone für Kampfpistole: Indicator: Miscellaneous Pistol Grenades

The indicator grenade is similar externally to the smoke and high explosive grenades except for the head which is parabolic. There is no fuze. The smoke train, a puff of reddish-brown smoke, is fired by the flash from the propellant. The indicator system begins to function when the projectile has been in flight for about two seconds. The weight of the complete round is 4.5 ounces; that of the grenade itself, 3 ounces. The marking on the base of the cartridge case is: DEUT. Z.

Nebelpatrone für Kampfpistole: Smoke: Miscellaneous Pistol Grenades

Nebelpatrone für Kampfpistole: Smoke: Miscellaneous Pistol GrenadesThis grenade is similar in appearance and construction to the high explosive grenade except that it contains a smoke generator instead of an explosive filler. It is fitted with a percussion type nose fuze which has a charge of gunpowder located just below the flash cap instead of a detonator. The projectile functions on impact and the gunpowder, ignited by the flash cap, ejects the smoke generator from the body of the grenade and at the same time ignites it. The projectile may be recognized by the following stencilled marking on the base of the cartridge case: NEBEL. Z.

Wurfkörper Leuchtpistole: Pistol Grenade: Ammunition for 27 mm Signal Pistol

Wurfkörper Leuchtpistole: Pistol Grenade: Ammunition for 27 mm Signal PistolThis pistol grenade is formed by adding to the egg-type hand grenade (Eierhandgranate 39) a plastic stem to which it is attached by a retaining tube. The tube contains the delay igniter at the forward end inside the grenade. An alloy flash tube connects this to the fuze which is located in the base of the stem. The fuze is separated from the primer by a safety pin which is pulled out before the grenade is placed in the pistol barrel. Upon firing, the firing pin strikes the primer which sets off the delay igniter, detonating the explosive charge after a delay of 4.5 seconds.

26 mm Wurfgranate Patrone 326 Leuchtpistole: Pistol Grenade: Ammunition for 27 mm Signal Pistol

26 mm Wurfgranate Patrone 326 Leuchtpistole: Pistol Grenade: Ammunition for 27 mm Signal PistolThis grenade, consisting of a rounded nose cap screwed to a cylindrical body, is equipped with four fins which are fixed to the base of the body. A brass or aluminum cartridge crimped to the grenade completes the assembly. A case containing the detonator and main filling is separated from a fixed firing pin in the nose of the grenade by a creep spring. The case is prevented from moving forward before firing by two metal balls in the base of the carrier. An arming rod inserted between the two balls prevents them from moving. This is forced out of the base by setback about ten or twelve yards after the grenade leaves the muzzle of the gun. The balls then slide out of their grooves and the case is free to move against the firing pin, exploding the grenade on impact.
