Abstract:

Certain metal organic salts e.g., lead or copper salicylate when used in double base propellants induce desirable insensitivities of burning rate to pressure and initial temperature. To understand this, the combustion wave zones luminous flame, dark, fizz, and surface reaction zones were examined by means of photography and fine thermocouples 4 micron bead. The metal salts significantly alter the surface and fizz zones. The surface zone accumulates carbonaceous material coincident with the appearance of an accelerated burning rate in the catalyzed case. No attendant change in surface heat release is detected. Coinciding with this carbonaceous layer occurrence are substantial 50 to 100 increases in conductive feedback from the fizz zone. This latter effect is believed directly responsible for the altered burning behavior though its origin may lie in the altered surface chemistry. Author
