“…Over the past few years, intensive research has led to high performance catalysts [76,77,79,81,[83][84][85]. These studies have dealt with efficiencies 4 95%, pressure drop levels around 100 mbar, thrust response times, transition times, and catalyst long-term storage aspects.…”

“…In order to suggest alternatives to toxic propellants, more than 100 propellants with significant reduced toxicity were established in a database and different propellants were investigated in different propulsion systems within the framework of the GRASP project [74][75][76]78,82,90,97]. A number of the investigated propellants were hydrogen peroxide [77,[79][80][81]86,88,89,95,96,98], ethanol [92], kerosene [101], ammonium dinitramide (ADN) [93,102,134,159,[169][170][171][174][175]179,181,183,[185][186]200], turpentine [101], dipentene [97], and high density polyethylene (HDPE) [74,75].…”

This paper describes an innovative catalytic system, able to decompose hydrogen peroxide. The development process has been carried out following a step-by-step approach. Firstly, a plug-flow reactor has been designed and used to perform a preliminary screening of catalysts prepared according to different techniques and identify the most promising preparation methods. A mono-propellant test bench has been then assembled to verify the behavior of a selected number of catalytic samples in a test environment closer to the actual operating conditions of a space propulsion system. The concept has been finally scaled-up to a hybrid configuration, based on the utilization of hydrogen peroxide as the oxidizer and high density polyethylene as the fuel. NomenclatureA = area c * = characteristic exhaust velocity D = space-averaged port diameter G = mass flux . m = mass flow rate O/F = oxidizer to fuel mass ratio p = pressure . r = space-averaged regression rate R = gas constant T = temperature x = conversion (ratio of final to initial hydrogen peroxide moles) γ = specific heats ratio η = c * efficiency Subscripts ox = oxidizer f = fuel th = theoretical meas = measured ad = adiabatic decomposition temperature c = post-chamber max = maximum measured value t = nozzle throat in = initial f = final Superscripts − = time-averaged value

This paper describes the development of a novel catalytic system capable of decomposing hydrogen peroxide. The system is based on ceramic honeycombs in yttria-stabilized zirconia, with manganese oxides as the active phase. The effectiveness of different catalyst preparation procedures, entirely developed in house, has been evaluated using a plug-flow reactor operating with diluted hydrogen peroxide vapors. A monopropellant test bench has been then assembled to verify the performance of a selected number of catalytic samples in a test environment closer to the actual operating conditions of a space propulsion system: the catalysts have demonstrated decomposition efficiencies exceeding 90%. The concept has been finally scaled up to a hybrid configuration based on the utilization of hydrogen peroxide as the oxidizer and high-density polyethylene as the fuel: the possibility to ignite and reignite the fuel grain has been demonstrated and propulsive efficiencies close to 90% have been measured.
