Parameters Affecting the Erosive Burning of Solid Rocket Motor
Increasing the velocity of gases inside solid rocket motors with low port-to-throat area ratios, leading to increased occurrence and severity of burning rate augmentation due to flow of propellant products across burning propellant surfaces (erosive ...

Preliminary research of composite rocket propellants including octogene [PDF]
Composite solid propellants based on ammonium perchlorate/hydroxyterminated polybutadiene/isophorone dyisocyanate including different contents of octogene (HMX) have been represented in this paper. The mass of HMX increased in relation to oxidant, with constant bimodal fraction ratio.

Mechanical properties of HTPB composite propellants in the initial period of service life [PDF]
Uniaxial tensile tests of different composite solid rocket propellant compositions, based on hydroxyl-terminated polybutadiene (HTPB), have shown that mechanical properties extensively change after curing, up to 100% of their initial values, during the ...

Burn rate of a novel boron-AN-water green solid propellant
A novel composition of green solid rocket propellant has been suggested and examined. Boron powder was chosen to serve as fuel, for its very high energetic potential, which exceeds that of other common metals, as well as that of fossil fuels.
