Power train specifications and detailed system design are investigated covering fuel cell system dynamic response, hybrid system size, fuel cell system start-up time, system specifications, and hybrid bus component dimensions and costs. 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.
