THE COMBUSTION OF POROUS ALUMINUM PLUGS WITH OXYGEN THROUGHOUT

Abstract

Combustion of aluminum with oxygen was experimentally studied in the porous-plug configuration. Porous aluminum plugs of different internal structures and void contents were burned at atmospheric pressure with O2 passed up through the specimens to emerge at the burning surface. Burning was achieved for an overall fuel-oxidant equivalence ratio variation of a factor of 4; burning surface regression rates approach 1 inch per second. Periodic accumulation and ejection of burning surface material at low O2 throughout levels appears similar to that exhibited by some aluminized solid propellant and hybrid propellant rocket motors. The results indicate that a porous-metal hybrid approach represents possibly the best means of achieving the ultimate performance potential of a chemical rocket motor.
