WebRocket Research Corporation (RRC), under NASA Contract NAS 7-755, has evaluated a monolithic catalyst bed for monopropellant hydrazine decomposition. The program involved the evaluation of a new hydrazine catalyst concept wherein open-celled foamed materials are used as supports for the active catalysts. Catalyst beds are the key components of any single-component chemical propulsion (monopropellant) for rocket engines. One of the best known catalysts used in monopropellant rocket engine systems (e.g. hydrazine – N 2 H 4) are prepared from aluminum oxide and iridium.
