Chapter 3.0 Vehicle Design 3.5 Fuel Storage and Production 3.5.5 Fuel Systems Comparison Based on the analysis described above, a comparison was made between the pressure and cryogenic hydrogen storage methods and directly carrying the fuel from Earth. The analysis was performed for both types of power systems, dynamic isotope power and PV battery power. The results of this analysis, shown in Table 3-22 and Figure 3-167, are based on consuming 0.1 kg of hydrogen peroxide per day. This rate was determined through the results of the mission scenarios and vehicle sizing. It is the amount of fuel needed for one round trip mission flight. This consumption number may not be representative of actual usage but was used as a means of comparison in the analysis. This rate represents a conservative mission goal of one Entomopter flight per day. The mass results also include the total storage system, including power production, as well as the amount of hydrogen or hydrogen peroxide carried. The reliability of the systems proposed was not considered in the analysis. It is obvious that the fuel production system would have considerably more risk then the fuel storage method due to the large number of systems and components necessary to produce the fuel.
