← ScienceWhich risk rises in solid rocket boosters from uncatalyzed propellant?
A)Decreased propellant burn rate✓
B)Reduced chamber pressure stability
C)Increased incomplete combustion products
D)Elevated nozzle erosion occurrence
💡 Explanation
A low catalytic activity slows the _deflagration_ burn rate because it raises the activation energy, therefore leading to lower thrust, rather than higher pressure or erosion, which would be related to excessive burn rates or altered conditions.
