Burning behavior of ADN-mixtures

Data on the optical combustion properties of ammonium dinitramide (ADN) systems as powerful oxidants for propellants and explosives are given from expts. using ADN mixed with paraffin in a mass ratio of 90:10 corresponding to a max. specific impulse. Burning rates of 50 mm/s were measured at 7 MPa and a pressure exponent of 0.8 was detd. Spectroscopic investigations yield to flame temps. in the range of the adiabatic flame temp. of 2960 K and give first hints to the chem. reaction mechanism of the ADN combustion with hydrocarbons.
