Unlike neat ADN and GAP, the ADN/GAP binary mixtures appeared to burn steadily within the whole pressure interval, showing no breaks on the burning rate vs. pressure dependences. In the low-pressure area, the mixtures burn with rates less than those of pure ADN and exceed it as pressure grows above 10 MPa. In the whole pressure interval, the mixtures burn with the rates higher than those of pure GAP. It was determined on the basis of flame structure investigation that the surface temperature of ADN/GAP mixtures is controlled by the dissociation reaction of ammonium nitrate (AN) formed in the condensed phase during ADN decomposition. Physical and chemical processes responsible for the observed combustion behavior of the mixtures are discussed. %8 2007-03-01
