Hydroxyl functional fluorinated monomers as combustion aids for solid fuel ramjet fuels

A method of using fluorinated hydroxy functional combustion aids (FHCA) in SFRJ fuels to encapsulate metallic particles within a fluorinated coating to improve exhaust velocity efficiency up to 4 percent, comprising:

• pre-reacting hydroxyl functional groups of the FHCA with reagents selected from the group consisting of oxiranes and anhydride curatives,
• adding the FHCA to SFRJ fuel comprising a polymer matrix to molecularly distribute and immobilize the FHCA in the polymer matrix, the ramjet fuel including metallic particles selected from the group consisting of boron carbide, aluminum particles, and amorphous boron, the FHCA selected from the group consisting of 1,1,1,3,3,3 hexafluoro-2-propanol, 2,2,2 trifluoroethanol, and 3-hydroxybenzotrifluoride;
• and encapsulating the metallic particles in the distributed and immobilized FHCA.
