Abstract
Disclosed is a stabilizer composition for rocket grade hydrogen peroxide (H2O2) which is not detrimental to the combustion performance of RDREs and not detrimental to the decomposition performance of catalyst beds while simultaneously greatly increasing the storability of H2O2 in rocket propellant management systems including but not limited to tankages and regenerative cooling combustion chambers.

A method for stabilizing propellant grade hydrogen peroxide (H2O2) for use as an oxidizer in a rotating detonating rocket engine comprising adding to the propellant grade H2O2 a stabilizing composition of nitrate (NO3−), phosphate (PO4−3) and tin (Sn), wherein
- a. a concentration of nitrate (NO3−) is 5 ppm or more;
- b. a concentration of phosphate (PO4−3) is 1 ppm or more;
- and
- c. a concentration of tin (Sn) is 4 ppm or more.
A rocket propellant management system for use with propellant grade hydrogen peroxide (H2O2) comprising a stabilizing composition of nitrate (NO3−), phosphate (PO4−3) and tin (Sn) wherein:
- a. a concentration of nitrate (NO3−) is 75 ppm or more;
- b. a concentration of phosphate (PO4−3) is 20 ppm or more;
- and
- c. a concentration of tin (Sn) is 20 ppm or more.
The system of 16 wherein the said stabilizers composition comprises Sodium Nitrate (NaNO3), Sodium phosphate dibasic dodecahydrate (Na2HPO4 12H2O) and Potassium Stannate Trihydrate (K2SnO3 3H2O).
