    摘要： This invention record describes the production of a low vulnerability propellant (LOVA) ingredients utilizing mixtures of alkyl nitratoethyl nitramines (alkyl NENAs) and/or bis (2-nitroxyethyl) nitramine (DINA) with nitrocellulose. Described compositions provide lower freezing points and decreases sensitivity while maintaining or surpassing output realized with currently used nitroglycerins/nitrocellulose mixtures. A process to provide for the production of desired mixtures of alkyl NENAs with each other or with DINA in a safe, cost-effective co-nitration process is disclosed. The process involves mixing together predetermined amounts of precursors for each of alkyl NENAs and/or DINA to be present in the final mix. Nitrating the precursors followed by a catalyst reaction, wash and neutralization step.

    摘要： Solid composite propellants are prepared by combining solid fuel and oxidizer particles, hydroxy-terminated prepolymers, and bonding agents which have polar functional groups to bond to the oxidizer particles and hydroxyl groups converted to isocyanate groups to bond to the binder. These bonding agents replace the non-reacted precursors as well as aziridine-type bonding agents in common use.

    摘要： Improved thermoplastic elastomer compositions having improved processing and mechanical characteristics without requiring addition of excessive quantities of plasticizer comprise at least one thermoplastic elastomer loaded with a crystalline modifier having a relatively low melting point. The modifier can be liquid at the processing temperature, resulting in increased ease in handling of the product. An exemplary crystallizable modifier is an alkylated pentacycloundecane dimer.

    摘要： Low-vulnerability component of explosive ammunition and process for initiating a charge of low-sensitivity composite explosive. The subject of the present invention is a low-vulnerability component of explosive ammunition consisting of a preferably metallic enclosure 1 containing a charge 2 of low-sensitivity composite explosive E and, as initiating relay, a plane wave generator 3 consisting, on the one hand, of a cylindroconical cap 7 made of composite explosive A, the large base surface having a diameter d greater than the critical diameter of the explosive E, the cavity 8 of this cap 7 being filled with a composite explosive B and, on the other hand, of a reinforcer made of composite explosive C, of thickness e greater than 0.1 d, the detonation pressure of the explosive C being higher than that of the explosive E. The detonability index according to the test for detonability behind a barrier is between 90 and 200 cards in the case of the explosives A, B and C and lower than 90 cards in the case of the explosive E. The invention also relates to the process for initiating the charge 2 using the generator 3.
