Description

  

      Raketen-Gesehoss.       Der Gegenstand vorliegender Erfindung  ist ein     Raketengeschoss,    bei dem die     Abbrenn-          zeit    der Treibladung verschieden eingestellt  werden kann.  



  Die beiliegende Zeichnung zeigt ein Aus  führungsbeispiel des Erfindungsgegenstandes.       Fig.    1 zeigt das     Raketengeschoss    im  Schnitt. Die Raketenkammer, die den Pulver  körper c aufnimmt, besteht aus einer Metall  hülse b, die an ihrem     hintern    Ende eine sich  nach     aussen    erweiternde     Gasausströmdüs-e    f  besitzt. Die     Ausströmöffnung    der     Düse    ist  durch einen     Ventilkörper    e abgeschlossen,  welcher Ventilkörper e durch eine Feder h  gegen die     Aus.strömöffnung    gepresst wird.

    Die Feder     h    selbst befindet sich in einem  Kasten i, in welchem sie durch Drehen der  Einstellschraube     k    auf gewünschte Spannung       gepresst    werden kann.  



  Der Raum zwischen Federkanten i und       Düsenwand    ist der Hauptsache nach für die       Abströmung    der Gase frei, nur eine Anzahl       Metallstege    g halten den Federkasten in  seiner Lage fest und nehmen einen kleinen    Bruchteil der     Ausströmfläche    der Düse für  sich     in    Anspruch.     Fig.    2 zeigt     einen    Quer  schnitt     C-D    durch diese     Stegpartie,    und       Fig.    3 zeigt einen Schnitt nach der     Richtung          A-B    der     Fig.    1.

   Die     Stege    sind dieser     Fig.    3  entsprechend nach vorn und hinten zum  Zweck der Verminderung der Widerstände       zugeschärft.    Zudem sind sie zur Radial  richtung sowie zur     Abströmrichtung    der  Gase, .die in     Fig.    3 mit dem Pfeil bezeichnet  ist, schief     gestellt,    so dass die austretenden  Gase das Geschoss um seine Längsachse  drehen.  



  Der Pulverkörper wird durch     irgendeine     Zündvorrichtung a entflammt. Die Verbrenn  gase füllen dann den     Hohlraum    zwischen  Pulverkörper c und dem     Ventilkörper    e. Der  fest aufsitzende Ventilkörper lässt die Gase  erst dann nach der Düse entweichen, wenn  der Gasdruck die Kraft der Feder h über  windet.  



  Dadurch, dass der Gasdruck, unter     wel-          wel.chem    die Raketenladung     abbrennt,    mit  der Federspannung eingestellt werden kann,      kann auch die     Abbrennzeit    der Treibladung       eingestellt    werden.



      Missile frame. The subject matter of the present invention is a rocket projectile in which the burn-off time of the propellant charge can be set differently.



  The accompanying drawing shows an exemplary embodiment from the subject of the invention. Fig. 1 shows the missile projectile in section. The rocket chamber, which receives the powder body c, consists of a metal sleeve b which, at its rear end, has an outwardly widening gas discharge nozzle f. The outflow opening of the nozzle is closed by a valve body e, which valve body e is pressed against the outflow opening by a spring h.

    The spring h itself is located in a box i, in which it can be pressed to the desired tension by turning the adjusting screw k.



  The space between the spring edges i and the nozzle wall is mainly free for the outflow of the gases, only a number of metal webs g hold the spring box in place and take up a small fraction of the nozzle's outflow area. FIG. 2 shows a cross section C-D through this web part, and FIG. 3 shows a section in the direction A-B of FIG.

   The webs are sharpened to this Fig. 3 in accordance with the front and rear for the purpose of reducing the resistance. In addition, they are inclined to the radial direction and to the outflow direction of the gases, which is indicated by the arrow in FIG. 3, so that the escaping gases rotate the projectile about its longitudinal axis.



  The powder body is ignited by any igniter a. The combustion gases then fill the cavity between the powder body c and the valve body e. The tightly seated valve body only lets the gases escape after the nozzle when the gas pressure overcomes the force of the spring h.



  Because the gas pressure at which the rocket charge burns down can be adjusted with the spring tension, the burn time of the propellant charge can also be adjusted.
