Serving as a fuel-air mixing chamber, and as a mounting point for other engine components, the large manifold (430 by 280 by 90 mm), in addition to being of lighter weight than aluminum, is designed to withstand cyclic vacuum fatigue ([greater than]1 million cycles at 85 kPa); overpressurization events; tensile, flexural, and compressive creep; and impact loading resulting from mishandling.
A rupture disc or bursting disc is a pressure relief device that protects a vessel or system from overpressurization.
The culprit for the overpressurization was determined to be the location of the differential pressure transducer that controls the secondary loop circulation pumps, and this transducer and its control sequence were examined by the class.
