Hexanitrohexaazaisowurtzitane (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo [5.5.0.05,9.03,11] dodecane) or CL-20 has attracted attention as a possible replacement for, or inclusion in, military and space propellants and explosives. CL-20 is a polycyclic nitramine with a higher crystal density, a higher heat of formation, and a better oxidizer-to-fuel ratio than conventional nitramines used in propellants. The effective life cycle management of CL-20 requires development of knowledge and technologies related to the consequences and attributes of CL-20 ...

The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.

There is a continuing need for safe, versatile rocket propellants, which are stable, nonvolatile, energetic, and easily demilitarized. Ionic liquids constitute a research area that is little explored for propellant ingredients and provides potential to meet these requirements. Enhanced dissolving power, density and compatibilities with a wide range of propellant ingredients make ionic liquids a very attractive class of materials for advanced state-of-the-art propulsion systems. The extreme polarity of these ...

6 pages

Authors: Forman A. Williams; CALIFORNIA UNIV SAN DIEGO LA JOLLA DEPT OF THE AEROSPACE AND MECHANICAL ENGINEERING SCIENCES

This research was directed towards developing new knowledge of combustion processes in liquid-propellant rocket engines. Attention was given to the combustion of different fuels, beginning with hydrogenoxygen but ultimately including multicomponent hydrocarbon mixtures representative of RP fuels, and to nonlinear processes of importance in combustion instability. Effects of detailed chemical kinetics on performance and stability were addressed by introducing systematically reduced chemistry that enables theoretical analyses to be completed thoroughly ...

Where as numerous partially azide-substituted titanium compounds had previously been reported, 1-7 no binary titanium azides were known. In a recent theoretical study the group 4 metal tetrazides M(N3)4 (M = Ti, Zr, Hf, Th) were predicted 8 to be vibrationally stable exhibiting tetrahedral structures with unique linear M-N-NN bond angles (see Figure 1). All previously characterized covalent binary azide species possess bent M-N-NN angles. In this paper we wish ...

The azido-group is highly energetic and adds about 70 kcal/mol to the energy content of a molecule. It is, therefore, not surprising that polyazides are highly endothermic compounds, and that their energy content increases with an increasing number 9f azido ligands. Compared to the relatively stable azide anion, which possesses two double bonds, the bonds in covalent azides are polarized towards a single and a triple bond, which greatly facilitates ...

The Dutch Ministry of Defence, the MoD, is responsible for purchase, maintenance and disposal of their ammunition. For ammunition purchase it is important to compare the expected lifetime of the ammunition of different suppliers. Once the guaranteed lifetime is expired it is of great significance to know whether the ammunition can still function well and safe for a few more years. During maintenance one needs to know how and when ...
