Definitions
- the composite fuels based on ammonium perchlorate (AP) / aluminum (Al) used today as solid propellants for rockets have high performance, good processability, good mechanical properties and, in practice, a flexible combustion behavior.
- the above types of fuel have a strong primary or secondary signature due to Al2O3 or HC1 in the exhaust gas.
- the signature is a serious disadvantage for practical use on carrier- and field-bound weapon systems, since launch ramps and launch sites can be easily located using a smoke trail that is visible from afar.
- Another disadvantage is the corrosive effect of the exhaust gases.
- DB fuels are relatively low in signatures, but have only low performance and unsatisfactory mechanical properties (thermoplastics).
- Energetic plasticizers e.g. nitroclycerin (NG), butanetriol trinitrate (BTTN), trimethylolethane trinitrate (TMETN), diethylene glycol dinitrate (DEGDN), bis-dinitropropyl formal / acetal (BDNPF / A) and others
- Inert binder systems eg polyester polyurethane elastomers, polyether polyurethane elastomers, polybutadiene polyurethane elastomers and others
- a reduction in the pressure exponent was found for DB fuels with nitramine contents below 50% and inert polyurethane binders as well as with the addition of heavy metal salts and soot.
- the burning rate remains at low values.
- the spectrum of properties is so unfavorable overall that these fuels have not found any practical use.
- Burn-moderating additives showed no significant influence on the pressure exponent when using inert binder systems.
- binder systems containing azide groups instead of inert binder systems (for example polyester polyurethanes) which lead to an increase in performance.
- These binders have a polyether or polyester-like chain structure that contain high-energy azide groups in the side chain.
- a glycidyl azidodiol with the following structural unit can be mentioned as an example of a binder containing azide groups: which can be cured with di- or triisocyanates (e.g. hexamethylene diisocyanate) to form elastomers (GAP).
- di- or triisocyanates e.g. hexamethylene diisocyanate
- the object of the present invention is to propose high-performance solid fuels with positive combustion behavior.
- a fuel consisting of high-energy nitramine compounds in proportions of 50-90% by weight, an energetic binder system containing azide groups consisting of polymers and plasticizers in proportions of 8-50% by weight and heavy metal catalysts in the form of lead and tin - or copper compounds in concentrations of 0.5-10% by weight.
- the fuels according to the invention preferably consist of 60-85% by weight of solid high-energy nitramine compounds which do not have any corrosive effects on decomposition Form gases and cause smokeless or low-smoke combustion in the fuel, i.e. show no or only minimal signature.
- binders containing azide groups and preferably 1 to 5% by weight of heavy metal catalysts there is a significant reduction in the pressure exponent (n ⁇ 0.6).
- High energy nitramine compounds such as octogen, hexogen, nitroguanidine, tetryl and others are preferably used. used.
- the binders containing azide groups used in the fuel system according to the invention can vary in the range of 8% by weight, preferably 15-40% by weight, the binder itself being 0 - max. Contains 80% by weight, preferably 30-70% by weight, of plasticizers.
- plasticizers In connection with azido polymers, all organic nitric acid esters or nitro compounds conventionally used in fuels can be used as energetic plasticizers. Nitroglycerin, butanetriol trinitrate, trimethylolethane trinitrate, diethylene glycol dinitrate or bis-dinitropropyl formal / acetal are preferably used as less sensitive plasticizers.
- inert plasticizers such as alkyl acetates, preferably triacetin and / or phosphoric acid, phthalic, adipic or citric acid esters, preferably dibutyl, di-2-ethyhexyl and dioctyl phthalate, dimethyl and dibutyl glycol phthalate, can additionally be used -2-ethylhexyl and diisooctyl adipate can be used.
- Curing to an azido polymer with high elasticity and extensibility is preferably carried out using trimeric isocyanates such as, for example, biuret trihexan diisocyanate or a combination of dimeric and trimeric isocyanates, hexamethylene diisocyanate and 2,4-toluene diisocyanate and isophorone diisocyanate are preferably used as dimeric isocyanates.
- trimeric isocyanates such as, for example, biuret trihexan diisocyanate or a combination of dimeric and trimeric isocyanates, hexamethylene diisocyanate and 2,4-toluene diisocyanate and isophorone diisocyanate are preferably used as dimeric isocyanates.
- the equivalent ratios can be varied between 0.4 and 1.2 NCO / OH proportions depending on the solids content.
- Pb, Sn or Cu compounds used as catalysts are preferably used in the form of oxides, organic salts (salicylates, stearates, citrates, resorcylates etc.) or inorganic salts, but complex compounds are also suitable.
- a further reduction in the pressure exponent can be achieved by adding small amounts of carbon or substances which supply carbon during combustion.
- Carbon black, activated carbon, carbon fibers or graphite are preferably used, the proportion of which is between 0.2 and 3% by weight, preferably between 0.5 and 1% by weight.
- the rocket solid propellants formulated in accordance with the invention can be used in all civil and military, rocket-based systems. They are particularly important in the case of military battlefield systems such as artillery, tank, and aircraft anti-aircraft or anti-ship missiles. Since, in contrast to AP composite fuels, no corrosive gases are generated, operating personnel and the launching system are not exposed to any stress.
- the fuels formulated according to the invention show a property profile that is not achieved by any previous solid fuel type: - Higher performance than double base fuels - Pressure exponent n ⁇ 0.6 - Burning rate at 100 bar r100> 9 mm / s - better chemical stability than double base fuels - viscoelastic mechanical properties - Significantly reduced primary and secondary signature with almost smokeless burning, without the addition of metallic fuels, - no corrosive exhaust gases
- column 1 shows a conventional solid propellant and compound according to the invention in columns 2 and 3 with their properties which are relevant for the use.
- the high burning rate and the very low pressure exponent of the fuels according to the invention are striking.
