Commercial and operation requirements, environmental and market drivers, and fuel processor modeling are examined. This report presents the results of a study assessing the design options for a solid polymer fuel cell bus. Problems encountered in the design are also presented.Įnergy Technology Data Exchange (ETDEWEB) ![]() Tradeoff studies were performed to optimize all factors of design, including survivability, performance, cost, and weight. The proposal was divided into six main subsystems: (1) scientific instrumentation (2) command, communications, and control: (3) altitude and articulation control (4) power and propulsion (5) structures and thermal control and (6) mission management and costing. The Titan 4 with a Centaur upper stage will be utilized to launch the craft into the transfer orbit. The mission lifetime is expected to be 18 years. The Pluto Flyby Exploration/Research Design (PFERD) mission will consist of a flyby spacecraft to Pluto and its satellite, Charon. ![]() Lemke, Gary Zayed, Husni Herring, Jason Fuehne, Doug Sutton, Kevin Sharkey, Mike PFERD Mission: Pluto Flyby Exploration/Research Design
