| description abstract | Abstract: Two satellites with different propulsion system designs were lost in 1993 and 1994 when blow-by from pyrovalves interacted violently with propellants. To prevent detonation of fuel due to the compression of hydrazine and its ignition by pyrovalve blow-by, use non-pyrotechnic valves or a zero blow-by pyrovalve design, or fire a pyrovalve only when there is a vacuum downstream of the valve. | |
