Definitions

  • This cap can thus protect the guiding optics of the ammunition, depending on the case, during a firing phase, for example, when crossing a seal; during a ballistic phase, in the case of a rocket or projectile; during a cruise phase, in the case of missiles.
  • the guiding optics is directly exposed to the impacts due to bodies present in the air and aerodynamic friction, or, it is protected by a detachable cap, to the approach of the target, the body of the ammunition which involves a risk of damage to the empennage deployed at the rear of the rocket or missile by the protective cap detached from the body of the ammunition.
  • the front body portion extends towards the rear body of the munition by an intermediate body of circular cylindrical shape of the same axis of revolution ZZ 'and of diameter D2 greater than the diameter D1 of the front body portion to form a first body shoulder, the intermediate body extending through the rear body of the munition, of diameter D3 larger than the diameter D2 of said intermediate body, to form a second body shoulder.
  • FIG. 1 shows a partial view in axial section of an embodiment of a guided rocket according to the invention
  • FIG. 2a shows a partial sectional view of a protective cap of the rocket of Figure 1;
  • FIG. 1 shows a partial view in axial section of an exemplary embodiment of a guided rocket according to the invention.
  • the tip 126 is rounded at its end to obtain the desired aerodynamic shape of the protective cap 20.
  • FIG. 3a shows a perspective view of the rocket body of FIG. 1 comprising the protective shield.
  • Figure 3b shows the protective shield only of the rocket body of Figure 3a
  • the protective shield 24 comprises a shield body 25 of round cylindrical circular shape having two main faces, a rounded circular edge 27 and close to the circular edge 27 of the shield a spoiler 150.
  • the protective shield is designed so that its shape circular cylindrical round of the shield marries the shape of the front body 14 of the rocket (see Figures 1, 3a and 3b).
  • the spoiler 150 subjected to centrifugal force would create an unbalance and strengthen the transverse component that tends to eject the shield 24.
  • FIG 5 shows an alternative embodiment of the rocket of Figure 1 according to the invention.
  • the cap 20 comprises only a pyrotechnic charge activated by a pyrotechnic cord in place of the layers 160, 170 of electrical conductors.
  • This other variant avoids the use of an igniter near the propellant charge and the expulsion during the destruction of the cap of the metal components that can damage the extended empennage of the rocket.
