I have real doubts about that part of the idea. Catalystic decomposition
will not be slow with high-concentration peroxide and an effective liquid
catalyst mixed well together. Mixing *in* the chamber sounds both better
and safer.

Once the rocket is firing, is it possible to use non catalysed HTP?


Yes, definitely. As with any propellant combination, once it's lit it
will generally stay lit, modulo combustion-stability issues. People have
built rocket engines using peroxide as oxidizer with no catalyst at all,
just a conventional ignition system.

Thanks Henry. I'm one step closer :-)
