RÉSUMÉ

The large-scale production of metal nanopowders opens the prospect of their widespread use in energetic materials. Coating metal nanopowders with organic compounds makes it possible to overcome the limitations inherent in the nanopowders. The coating results in deagglomeration, improved chemical stability, and better compatibility, which enable the use of the metal nanopowders in high-energetic materials (HEMs). A partial or full change in micron-size aluminum in HEMs has shown a qualitative difference in the formation dependences of the particles-size distribution function at the nozzle output on their input parameters. The resulting losses of the full impulse in the nozzle for the considered variants of the nano-size aluminum use are integrally 2.6% lower in comparison with propellant formulations containing only conventional aluminum powder.
