摘　　要：A wide variety of hydroxyl-terminated polybutadiene(HTPB)based fuels areexperimentally assessed in anaerobic reaction.In this study HTPB pyrolysis is investigatedusing a CO laser as the energy source.The formulation of the solid fuel samples issystematically changed to isolate the effects of carbon black,metal fuel additives,and smallamounts of oxidizer.In addition,chemical changes to the fuels including curative type andbase polymer are varied.Rates of pyrolysis reaction are reported for a wide range of solid fuelsapplicable to ramjet application.Processes involving the sintering together of metal particles,accumulation of carbon black,and formation of a melt layer are found to affect the reactionrate.It is determined that the surface composition is the most influential factor influencing theregression rate of HTPB based fuels.
