BALLISTIC AND COMBUSTION PROPERTIES OF HIGH-PRESSURE EXPONENT HYDROCARBON-BASED FUEL-RICH PROPELLANTS
ABSTRAKT
The ballistic properties of hydrocarbon-based fuel-rich propellants can be manipulated by various methods. Incorporating fine AP and large surface area ferric oxide particles can substantially increase the burning rate. Alternative oxidizers like KP and RDX can lower the burning rate. Studies showed that the burning rate measurements are highly dependent on three measuring techniques: optical bomb, strand burner and BEM test motors. Pictures of burning fuel-rich propellant showed the formation of a thick porous zone during combustion. The flame temperature of fuel-rich propellants measured with visible spectroscopy differs from values calculated with thermodynamic calculations.
