A recent patent for LANL (http://www.google.com/patents/US20140109551)
seems to be describing a high-energy solid fuel with lots of nitrogens and
hydrogens (dihydrazinotetrazine, triaminoguanidinium
5,5′-dinitro-3,3′azo-1,2,4-triazole, or triaminoguanidinium azotetrazolate)
bound in HTPB or an alternative binder which would be decomposed in an
inner solid monopropellant motor with nozzle. In their figure, it is in an
end-burner configuration, blowing down through a hollow-core oxidizer grain
(they say either pressed AP, pressed AN, or a combination) through an outer
nozzle.
The patent was found by UhClem on TRF, not by me. (Just giving credit)
It is basically a monopropellant solid with an AP "afterburner" to react
with the oxygen poor exhaust of the fuel.
