Claims

1. THE PROCESS OF MANUFACTURING AN INCENDIARY BOMBLET HAVING A STREAMLINED PORTION WITH INTEGRAL EXTENDING FINS AT THE REAR SECTION AND FIRST FIRE COMPOSITION PORTION IN THE FORWARD SECTION OF SID BOMBLET WHICH COMPRISES:

(A) PROVIDING A THERMITE-TYPE POWDERED MIXTURE OF A SOLID METAL OXIDE POWDER AND A POWDERED METAL, (B) PROVIDING A MOLD HAVING A MOLD CAVITY CORRESPONDING TO THE SHAPE OF THE DESIRED BOMBLET, (C) FILLING A PORTION OF SAID MOLD WITH POWDERED MIXTURE, (D) PROVIDING A POWDERED FIRST FIRE COMPOSITION WHICH WILL IGNITE BY PERCUSSION TO BURN WITH A TEMPERATURE SUFFICIENTLY HIGH TO IGNITE SAID THERMITE-TYPE POWDERED MIXTURE, (E) ADDING A QUANTITY OF SAID FIRST FIRE COMPOSITION TO SAID MOLD, (F) PRESSING THE CONTENTS OF SAID MOLD IN THE MOLD WITH SUFFICIENT PRESSURE TO FORM SAID CONTENTS INTO A COMPOSITE SHAPE CAPABLE OF BEING REMOVED FROM THE MOLD AND HANDLED WITHOUT DISINTEGRATION, (G) REMOVING THE RESULTING COMPOSITE SHAPE FROM SAID MOLD, AND (H) HEATING THE COMPOSITE SHAPE AT AN ELEVATED TEMPERATURE BELOW THE IGNITION TEMPERATURE OF THE COMPOSITE SHAPE UP TO 1400*C. TO PRODUCE A SINTERING OF THE COMPRESSED POWDERED MIXTURES FORMING SAID COMPOSITE SHAPE.
