EFFECT OF CR2O3 ON THE BURNING CHARACTERISTICS OF AN / MGAL – BASED COMPOSITE SOLID PROPELLANTS
Keywords:
AN/MgAl - based solid propellant,, catalytic combustion,, burning rate,, pressure vessels,, high-speed cameraAbstract
In this work studied on the burning characteristics of AN / MgAl – based solid propellant catalytic combus-tion with the addition of Cr2O3. The addition Cr2O3 improves ignition at low pressures. However, the addi-tion of Cr2O3 increased burning rate, the use of mechanical alloy MgAl as an oxidizer allowed propellant ignited at low temperatures. Samples were burned in the combustion chamber under nitrogen pressure 1MPa, 3MPa and 5MPa with a video camera determined burning rate
