Electrical System & Lights

For the electrical system I’ve read and re-read Bob Nuckolls’ book, The AeroElectric Connection, and applied a ton of Bob’s mojo into my system architecture.  In addition, I spent a lot of time discussing it with my ‘Electrical Systems Mentor,’ Eric Jones, who has a lot of cool, unique and—IMO—necessary electrical system products at Perihelion Design.

I’ll be utilizing Bob’s Z-13/8 dual-layer architecture (Main Bus & Endurance [back-up] Bus), while leaning towards his original precursor to that architecture: the Z-8.  The Z-8 simply uses more traditional components (for example: an aircraft voltage regulator with built-in overvoltage protection versus a Ford auto voltage regulator requiring an external overvoltage module) rather than slightly more, shall we say, eccentric or esoteric components.

14V Electrical System utilizing a Z-13/8, 4-bus architecture:

  •         4 Busses: Main Bus, E-Bus, Battery Bus, X-Bus (ATC fuse blocks)
  •         Battery Bus to E-Bus B&C S704-1 Relay
  •         Super Schottky Diode (Main Bus to E-Bus feed)
  •         Tyco Circuit Breakers x 5
  •         B&C “Forest-of-Tabs” Grounding Bus x 2
  •         Avionics Ground Bus (Aeroelectric)
  •         Odyssey PC680 16 AH Battery
  •         LRC-14 14V B&C Voltage Regulator
