Аннотация:7-Cyanomethyl-7Н-difurazano[3,4-b:3′,4′-f]furoxano[3′′,4′′-d]azepine (Az(O)CH 2 CN) and 7-cyanomethyl-7Н-trifurazano[3,4-b:3′,4′-d:3′′,4′′-f]azepine (AzCH 2 CN) are synthesized for the first time aspotential dispersants of solid fuels for gas generator engines; their molecular structure, enthalpies of combus-tion, and formation are determined; and the relative aircraft flight range is estimated when usingAz(O)CH 2 CN and AzCH2CN as fuel dispersants.
