Subscale Motor to Investigate the Effect of Initial Temperature on the Burning Process for Solid Propellants

Popis výsledku v původním jazyce

The effect of the initial temperature on the burning rate for three compositions of double based propellants (ROP, GRAD 98 and GRAD 06) was characterized. These propellants were fired in a subscale rocket motor and the propellant burning rate was measured as a function of pressure and initial temperature. Variations in the duration of different burning zones were observed. The operating pressure ranges were 5 –24 MPa and the temperature ranges were - 60 °C to +60 °C. This study concluded that raising the initial temperature of the propellant grain increases its ignitability and leads to higher burning rate with higher operating combustion pressure and consequently shortens the burning time.
