power system operations control (1 Ergebnisse)

Hardcover. Zustand: New. Zustand des Schutzumschlags: New. 1st Edition. The EPS consists of three subsystems: power reactant storage and distribution, fuel cell power plants electrical power generation and electrical power distribution and control. The PRSD subsystem stores the reactants cryogenic hydrogen and oxygen and supplies them to the three fuel cell power plants, which generate all the electrical power for the vehicle during all mission phases. In addition cryogenic oxygen is supplied to the environmental control and life support system for crew cabin pressurization. The hydrogen and oxygen are stored in their respective storage tanks at cyrogenic temperatures and supercritical pressures. The storage temperature of liquid oxygen is minus 285 F and minus 420 F for liquid hydrogen. The book presents a very systematic presentation of the subject matter in simple and lucid language.
