Fuel and fuel igniter for ram jet and rocket

Claim 2

A FUEL UNIT FOR FORCED AIR FLOW RAM JET COMBUSTION CHAMBERS COMPRISING A BRIQUET OF COMPRESSED MOIXED POWDERED OXIDANTS AND REDUCTANTS, A MAGNESIUM SHELL ENCASING SAID BRIQUET, AND A FILM OF PLASTICIZED NITROCELLULOSE CONSISTING OF 25 PERCENT BY WEIGHT OF ALCHOL-WET NITROCELLULOSE IN 75 PERCENT BY WEIGHT OF DIBUTYL-PHTHALLATE BETWEEN THE BRIQUET AND SHELL.

Claim 3

A fuel unit for use in a forced air flow ram jet combustion chamber comprising a solid cylindrical briquet of compressed powder, said powder being a mixture of reductant particles and oxidant particles with the oxidant particle concentration being less than the stoichiometric value for the compounds resulting from the combination of said oxidant concentration with the reductant concentration, a cylindrical combustible metal shell having open ends, said shell surrounding the periphery of said briquet, a film of plasticized nitrocellulose between said shell and said briquet, a solid cylindrical igniter inserted in one end of said shell so as to abut against the full cross-sectional area of one end of said briquet, an electric squib mounted on said igniter, the other end of said shell being adapted to fit over a cylindrical skirt section mounted in said combustion chamber, said shell and film being exothermally combustible in air whereby upon ignition of said one end of said briquet said briquet and shell burn at a controlled rate throughout the length of said briquet, with the burning proceeding toward the opposite end of said briquet over constant successive cross-sections of said fuel unit, said cross-sections being taken in planes substantially perpendicular to the axis of said briquet.

Claim 4

A fuel unit for use in a forced air flow ram jet combustion chamber comprising a solid cylindrical briquet of compressed powder, said powder being a mixture of reductant particles and oxidant particles with the oxidant particle concentration being less than the stoichiometric value for the compounds resulting from the combination of said oxidant concentration with the reductant concentration, a cylindrical combustible metal shell having open ends, said shell surrounding the periphery of said briquet, a film of plasticized nitrocellulose between said shell and said briquet, a solid cylindrical igniter inserted in one end of said shell so as to abut against the full cross-sectional area of one end of said briquet, an electric squib mounted on said igniter, the other end of said shell being adapted to fit over a cylindrical skirt section mounted in said combustion chamber, said shell and film being exothermally combustible in air whereby upon ignition of said one end of said briquet said briquet and shell burn at a controlled rate throughout the length of said briquet, with the burning proceeding toward the opposite end of said briquet over constant successive cross-sections of said fuel unit, said cross-sections being taken in planes substantially perpendicular to the axis of said briquet.
