Laboratory Simulation of the Effect of Rocket Thrust on a Precessing Space Vehicle [PDF]
Ground tests of solid propellant rocket motors have shown that metal-containing propellants produce various amounts of slag (primarily aluminum oxide) which is trapped in the motor case, causing a loss of specific impulse.
