A Novel Kind of Green Solid Propellant Containing H2O2 Cured at Room Temperature (SPHP)
A novel kind of green solid propellant containing H2O2 cured at room temperature (SPHP) was prepared by a "two-steps" method, and its stability, mechanical properties, sensitivity, and combustion behavior were characterized. Stable storage of SPHP can be achieved at room temperature by selecting propellant ingredients with perfect compatibility with H2O2 and the addition of a complex stabilizer into propellant formulation. In addition, the obtained SPHP showed a lower tensile strength and higher elongation compared with conventional solid propellant. The experimental results showed that the sensitivity of SPHP was considerably low, but its combustion efficiency and C* efficiency were really high. The hot firing tests demonstrated the stable and smokeless combustion of SPHP, as well as its combustion behavior within the pressure range of 2-10 MPa was in agreement with Vieille's law and thus can be represented by r = 9.95P(0.57).
