Description

9 p.The stabiliser content, sample mass, thermal and kinetic properties of a nitrocellulose propellant м/ere followed during the accelerated ageing at 100 °C. The differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used for determination of the thermal and kinetic properties, while stabiliser content has been determined by UV-VIS spectrophotometer. It was found out that, at selected ageing temperature, the stabiliser consumes almost completely after four-five days, while at the same time some thermal properties do not change so significantly (e.g. onset, endset, and peak maximum temperature on DSC thermogram). The kinetic and thermal parameters decrease with the ageing, however this decrease is not monotonous along the investigated ageing period.
