摘要:
A projectile includes an ogive at a forward end and a projectile body removably coupled to an aft end of the ogive. A signal dye or a filler material is located within a first cavity in the projectile, wherein the first cavity is at least partially located within the ogive. A pyrophoric material is also located within the first cavity, wherein the pyrophoric material is hermetically sealed either within or by the first cavity.

A training ammunition projectile has a projectile body comprising a head with a frangible ogive designed to burst when the projectile strikes a target. One or more marking agents, disposed in the head for marking the position of the target upon its release when the ogive has burst, include 1) chemi-luminescent components, disposed in separate frangible compartments, which mix and react chemically with each other when the compartments break up on setback, causing the mixed components to luminesce, and/or (2) a low density, fine, dry powder material disposed in the head and designed to create a plume, both for marking the target when the projectile strikes the target. A dry thermal material, disposed in a separate compartment in the head and designed to be exposed to oxygen or air upon setback, due to the initial acceleration and the centrifugal forces, produce an exothermic reaction and emit heat during flight of the projectile, thereby to increase the temperature of the marking agents during flight and provide an Infrared marking signature when the projectile strikes the target.

The present invention refers to a fragmentable aerodynamic device comprising a body which comprises a series of gas-generating units (1, 2 and 3), each one of which has a cylindrical casing comprising a pan (4) and a closing lid (5), where there is a combustible mix (6), being the different casings axially coupled between one another, having one of the end units (3) an ignition fuse (8), where each one of the casings has an internal coaxial core (19) which is located between the bases of the casing and has an axial drill going through said bases, except for the external base of the end unit (1) which does not have the fuse (8), whose drill is designated for having a fire-transmitting mix (20); and characterized in that said casings have on their wall mutual coupling and fixing -means, which can be released by the pressure of the gases generated by the combustion of the transmission mix and the combustible mix contained in each casing.
摘要:
The aim of the invention is to create multi-spectral fog walls, in which the threat direction, threat distance, wind direction, wind speed, driving direction, and driving speed are taken into consideration in the dispensing of the visual and infrared line-of-sight interruption over time and space. In order to determine the effectiveness or effectivity of the fog wall (11, 13), a camera (4) and/or a thermal imaging device (5) is combined with a known launcher (2) and the images of both are evaluated in a computer (3), wherein in the evaluation of said information, the fog wall (11, 13) is stabilized or expanded if certain criteria are not reached. The production of a fog cloud (11, 13) that is opaque in the visible wavelength range but that has a residual transmittance is manipulated by cleverly choosing or selecting and adjusting the fog substance (a) itself, the fog concentration (c 1 , c 2 , c 3 ), the thickness of the fog wall (d 1 , d 2 , d 3 ), and the concentration of infrared particles over time and space during the fog burn-off. Disturbances are substantially eliminated by the digital image processing of a thermal image on the friendly side, and the thermal image is thus optimized.
摘要:
Es wird ein Nebeltopf mit einer pyrotechnischen Wirkmasse (14) und mit einem Zünder (18) beschrieben, der zum Zünden der Wirkmasse (14) vorgesehen ist. Die pyrotechnische Wirkmasse (14) enthält eine Chemikalien, die beim Abbrand der Wirkmasse ein Säureanhydrid entwickelt, das Luftfeuchtigkeit anzieht, die als Nebel ausfällt. Der Nebeltopf (10) weist mindestens ein mit Wasser gefülltes Behältnis (20) auf, das bei der Zündung der Wirkmasse (14) zerstört wird, um das Wasser freizugeben und eine Luftfeuchtigkeit zur Nebelerzeugung zu bewirken.
