The invention relates to a spin-stabilized grenade with a projectile jacket and a the floor cavity terminating, separable floor, wherein one or Several additional devices are included that can be used after an ejection charge has exploded with the Floor to be ejected and z. B. by a parachute a greater delay than that Obtained bullet jacket, and wherein the additional device, for. B. the parachute, in a cylindrical Container is housed, which along its surface lines in two or more shell pieces is divided, which after the explosion or after ejection from the projectile jacket the content, z. B. the parachute, release.

Known grenades of this type have the following disadvantages: If the projectile in flight after a a predetermined time is shared and the additional devices (e.g. a lamp with a Parachute) are separated from the shell of the grenade, it has been shown that the one behind the parachute Falling parts of the grenade into the parachute and destroying it. Object of the invention is to eliminate this disadvantage.

According to the invention this is achieved in that one of the shell pieces transversely to the axis of the cylindrical Container is divided into two or more arcuate lamellae.

An embodiment of the invention, applied to a light grenade, is described below under Referring to the drawing described, where F i g. 1 a flare grenade in section and

F i g. Figure 2 shows this flare grenade after the ejector charge has exploded.

F i g. Fig. 1 shows a flare grenade which has a detonator 1 at its front end. The detonator 1 is attached to the tip of the projectile jacket. A luminous element 3 and a parachute 4 as well as a container 5 for the parachute 4, which is divided in the axial direction, are provided in the cavity of the projectile jacket 2. The part 5 δ of the container 5 is divided transversely to the axis of the container into three arc-shaped lamellae 5 V, Sb " and Sb '" . The floor 6 consists of a substantially flat plate. The floor 6 is held on the floor jacket 2 by means of shear pins 7.

The grenade works in the following way: When the grenade has flown a predetermined distance, it ignites the igniter 1 is a powder charge which is attached in front of the luminous element 3. This will also the filament 3 ignited. By the gas pressure generated in the front end of the grenade, wer-grenade

cut off by the shear pins 7, and the projectile jacket 2 begins a relative forward movement with respect to the remaining parts of the grenade. When a third of the length of the container 5 is outside the projectile jacket 2, the rearmost third of the lamella 5 V of the half-shell forming part S b is released. This rearmost lamella Sb 'is ejected in the radial direction by the centrifugal force. This lamella 5b ' is then strongly decelerated by the air and quickly moved away from the rest of the grenade.

When the next third of the sleeve 5 a, Sb has moved out of the shell 2, the lamella Sb ″ of the container half 5 δ is also ejected in a similar manner.
When one, and even more so, when two of the slats 5b ', 5b "are ejected, the internal pressure resulting from the packing of the parachute, as well as the centrifugal force, act on the parachute, so that part of the parachute through the hole is pressed out, which has arisen after removing the lamellas 5 b ' and Sb ". The airflow then grips the parachute and pushes it backwards. The parachute thereby transmits a force to the edge of the projectile base 6, which is stabilized by the rotation, the projectile base 6 being steered from the path of the grenade by the gyro effect. Then the floor 6 begins to tip over and, because of its disc

form to slide past the rest of the grenade. At this moment the inner ones are Parts of the grenade are still under the action of the pressure generated in the front part of the grenade therefore slowly moved backwards.

Later, when the entire container half 5 a and the last lamella 5 V ″ are freed from the projectile casing 2, the parachute can unfold completely and thereby brake the luminous element very strongly.

The invention is not limited to a flare grenade. It can also be used for other devices be used, e.g. B. for measuring body for the determination of temperature and humidity.

The additional devices for delaying the grenade do not necessarily need to be used pass a parachute. The invention is always useful when the internal, additional devices after the explosion, a greater deceleration than the front parts of the grenade are supposed to receive and the rear parts of the grenade should be delayed even more so. The invention can also be used if you want to get the floor of the shell out of the path of the shell with certainty is controlled.

Claims (1)

Claim: Spin-stabilized grenade with a projectile casing and a separable floor, which closes off the projectile cavity. B. obtained by a parachute a greater delay than the projectile jacket, and wherein the additional device, e.g. B. the parachute, is housed in a cylindrical container which is divided along its surface lines into two or more shell pieces, which after the explosion or after ejection from the projectile jacket the contents, z. B. release the parachute, characterized in that one of the shell pieces (Sc, Sb) is divided transversely to the axis of the cylindrical container (5) into two or more arcuate lamellae (5 b ', Sb ", Sb'") .
