Polynitromethyl derivatives of furazano[3,4-e]di([1,2,4]triazolo)-[4,3-a:3′,4′-c]pyrazine as components of solid composite propellants

Resumo

The energetic potential of solid composite propellants (SCP) with furazano[3,4-e]di([1,2,4]- triazolo)[4,3-a:3′,4′-c]pyrazine including trinitromethyl (C(NO₂)₃), fluorodinitromethyl (CF(NO₂)₂), and (difluoroamino)dinitromethyl (C(NF₂)(NO₂)₂) groups was estimated based on thermochemical calculations. It was shown that C(NO₂)₃ and C(NF₂)(NO₂)₂ derivatives can constitute the basis of metal-free compositions of SCP with a specific impulse from 251 to 263 s, i.e., comparable or superior in efficiency to HMX-based propellants.
