Abstract:

The two parts of the report deal successively with chemiluminescence in flames and with combustion of solid propellants. Relationships between chemiluminiscence CL and chemi-ionization CI on one hand, and the molecular structure of the fuel on the other hand have been put forward, in particular the structure of hydrocarbon fuels have been investigated. Applying the multimicrojet burner technique for the simulating study of heat transfer from the reaction zone onto the regressing surface of solid propellants, it has been possible to investigate the dependence of the heat release on parameters such as total flow, distribution modes of gases, dilution and richness of flammable mixture and to correlate the heat release as a function of the burning velocity alone. Moreover, a new reliable technique to prepare cigarettes of polymthyl methacrylate for hybrid combustion has been developed where one can get rid of any trace of acetone, and where heat losses to the wall of the tube are avoided during the burning process. Mass burning rates of PMM with N2O and O2 have been recorded, and the porosity of the sample has been studied.
