    Notes: Die Absorptionsspektren im ultravioletten und sichtbaren Bereich sind ein wichtiges Hilfsmittel zur Aufklärung der Elektronenstruktur von Molekeln. Die Zuordnung einer Absorptionsbande wird wesentlich erleichtert, wenn man außer der Energie (Frequenz) und Intensität der Bande auch die räumliche Orientierung des zugehörigen Elektronenoszillators in der Molekel kennt. Es wird eine Übersicht über die Methoden zur Bestimmung dieser Orientierung gegeben. Anschließend wird die Messung und Deutung des Polarisationsgrades der Fluoreszenz bei Erregung mit polarisiertem Licht und in verschiedenen Absorptionsbanden beschrieben.

    Notes: All high explosives, at least the ones used in military applications, have a specific minimum detonation radius, Rmin with which the detonation can change its direction through 90° or 180°. It is to be emphasized that this applies not only to thc so-called insensitive high explosives, but the sensitive explosives of course have smaller radii than the insensitive ones.The corner-turning distance, As, determined in the radial test, also corresponds to the minimum radius, Rmin for the detonation wave to invert its direction through 180°. The radial test is a simple method, with regard to both design and analysis, that is suitable for determining the 90°-distance, or the minimum detonation radius, Rmin.

    Notes: Definitive conclusions about high and low order reactions can be drawn from individual framing-mode pictures of a rotating mirror camera record, when both the vellocity of the axial propagation of the reaction along the outer contour and the velocity of radial expansion of the reaction products are analysed at various distances from the plane of initiation. In this, the intensity of the reaction can be assessed quantitatively from the radial expansion velocites, even when, for example, a penetrating shaped charge jet induces an axial drag wave in the test charge. A detailed description is given of the test set-up and of the test results obtained with charges exposed to the impact of a shaped charge jet.

    The importance of jet tip velocity for the performance of shaped charges against explosive reactive armor (1994)
    Weinheim : Wiley-Blackwell

    Notes: It is shown, that the portion of a shaped charge jet that emerges from explosive reactive armor is longer or at least less disturbed if the jet tip velocity can be raised. Generally, the residual jet length largely depends on the ratio of the reaction time of the armor and the standoff of the shaped charge from the armor.

    Influence of Transverse Air or Inert-Filled Gaps in HE Charges on the detonation velocity (1995)
    Weinheim : Wiley-Blackwell

    Notes: Gaps 0.8-mm wide and transverse to the direction of detonation in high-performance high explosive compositions, such as squeeze cast TNT/HMX (15/85) or pressed HMX/B (97/3), show no measurable time delay, or it must be less than 50 ns. As expected, delay times increase with the gap width. A surprising result, however, is the convex shape of the time delay curves, which begins at a gap width of about 1 mm. The delay time curves from air and plexiglass-filled gaps resemble one another very much.

    Analysis of a shaped charge jet with the double-orthogonal-synchro-streak technique (1995)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 20 (1995), S. 116-122

    Notes: Recording the trajectory of a fully-particulated shaped charge jet at two different positions along its flight path, in two mutually orthogonal planes at each recording station, allows the decomposition of the overall transverse velocities of the particles into two components. This can be done by analysing the differences in the deviations observed at the two stations. The overall transverse velocities are composed of the vector sums of those lateral- or off-axis velocities which are intrinsic to the collapse process, and additional increments that are superimposed later as a result of particulation itself. In this paper the “IEPG Shaped Charge” has been used as an example to demonstrate the Double-OSST measurement technique.In these experiments, the overall transverse velocities derived are clearly larger than those seen between the collapse line and the first observation station. On the “Z” diagram (dispersion to the charge axis), the measurements made on this shaped charge do not exhibit random radial dispersion in all direction, but rather the particles spread out into a fan which expands more or less within one quadrant.

    Influence of Longitudinal Gaps on the Detonation Front (1995)
    Weinheim : Wiley-Blackwell

    Notes: Precursor air shocks with velocities that are 50 % higher than the velocity of detonation occur not only in cylindrical holes, but also in flat slits. By attaching to the test charge a sufficiently long plexiglass body with the same hole or slit profiles it is possible to observe the end face of the test charge and, thus, to record the changes in the detonation profile caused by slits, in particular by such that are oblique to the direction of detonation. One result is, that there is no through-detonation across thin slits that are at a flat angle to the detonation wave.

    Influence of the Initiation Intensity on the Radial Detonation Breakthrough (1995)
    Weinheim : Wiley-Blackwell

    Notes: Initiation intensity of a booster charge was varied by inserting plexiglass layers of different thicknesses. The time differences between shockwave arrival in the acceptor charge and the axial and radial detonation breakthroughs were determined, as well as the distance of the first radial breakthrough from the initiation plane - referred to as the 90° distance Δs or Corner Turning Distance (CTD). Changes in the initiation time and Δs are small as long as the initiation intensity is sufficiently above to the threshold value. This result applies for cast explosive charges, TNT/RDX (35/65), Composition B type charges, and high performance pressed charges, HMX/Binder (96/4).

    Detonation Studies with a Ballistic Range Camera (1995)

    Notes: With an appropriate test setup, the Hadland Photonics Ballistic Range Camera (SVR), designed primarily for exterior and terminal ballistics, can also be used very well for studying initiation events and analysing a variety of detonation phenomena. This paper discusses detonics experiments carried out with the Ballistic Range Camera explaining in detail the test setup and the analysis of the results. The ability of the camera system to superimpose up to 16 images on a single frame allowed particularly detailed examination of detonation propagation, velocity, corner turning distance and the non-reacting radial zones.
