Hybrid rocket engine design?

[HattoriHanzo]

I am looking for equations on designing hybrid rocket engines.
Solid propellant such asphalt and H2O or O2 as oxidizer.

Design off nozzle, cumbustion chamber, heat resistance materials, cc pressure calculations, fuel etc etc. As much as possible regarding hybrid rocket engines. Preferably with complete mathematical expressions.
On the web or in books.

I am not intend to build a engine but I am very interested to read about it.

Anyone read the book:

Rocket Propulsion Elements, 7th Edition
George P. Sutton, Oscar Biblarz
ISBN: 0-471-32642-9

?

There is one chapter regarding Hybrid Propellant Rockets. Seems to be a very comprehensive book.
