description abstractDescription of Driving Event:
Computer mathematical models had shown the engine to be sensitive to small changes in propellant conditions, and that timing relative to opening the propellant valves was critical. Expecting difficulties, a cautious step-by-step plan was followed to explore the start sequence in small time increments. It took 35 weeks and a series of 37 test, including 13 turbopump replacements to extend reliable performance form the 2-second startup transient to main power level.
