Optimisation study of a homogeneously-catalysed HTP rocket engine

The decomposition of hydrogen peroxide (HTP) using a liquid catalyst offers an alternative to the employment of traditional catalyst packs. A test rig has been used to estimate the length of chamber required for complete decomposition to take place for the case of HTP with a phosphorus content some 10000 times the level normally associated with rocket-grade HTP. Complete decomposition within a 10 mm advection length was achieved.
