Combustion of composite solid rocket propellants.

AIAA Journal, 1969
CONSIDERABLE work has been done on solid rocket ^->< propellants using various fuels (often polymers) and oxidizers. Recently Rastogi and Ouseph have studied the combustion of phenol-f ormaldehy de/NH 4C10 4 system . They observed that the rate of burning decreases as the amount of cross-linking increases in the polymer.

Burning of Nano-Aluminized Composite Rocket Propellants

Combustion, Explosion and Shock Waves, 2005
Several aluminum nanopowders were examined and compared with the final goal to evaluate their application in solid rocket propulsion. A detailed investigation of pre-burning properties by the Brunauer-Emmet-Teller method, electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy was carried out.
