I decided on an all DC system at 96V (Battery Direct Bus) to 112V (Primary Bus).
Pumps for fuel/oxidizer, coolant, hydraulics, etc. are ECM/BLDC motors because they run cooler, produce high amounts of torque at lower speeds, etc.
Battery Direct Bus powers Cockpit Essential Bus and Battery Bus towards aft for fuel boost pumps for reactor start.
Primary Bus powers Cockpit Primary bus (which in turn can power the Cockpit Essential Bus) as well as buses yet to be defined for hydraulics, coolant, sensors, etc.
Charger powered by Primary Bus charges a battery which supplies the Battery Direct Bus through the Battery Master Switch.
Reactor is a fuel cell powered by fuel/oxidizer. For simplicity of the system a hypergolic mixture is ideal so we don’t have to worry about ignitors.
Engines are straight turbojet in VTOL, then afterburners for ascent. The fan shuts down as the density of the atmosphere decreases. Afterburners become pure rockets. Engines are 100% powered by fuel/oxidizer since there is no oxygen in the atmosphere for this military arena.
Using an old curtain rod, some leftover 4″ PVC pipe, and an old velvet (stretchy) dress, my wife was able to put together this headband holder for our daughter. Total capacity is 40 headbands.
