Posted: Fri Sep 23, 2022 5:37 am Post subject: Regulator location

I’ve been trading emails with another builder and they asked my thoughts on the location of the ship’s voltage regulator.  “What are the pros and cons to mounting the regulator on the occupant side of the firewall.”



My thoughts are below but I think this is a question better served by this forum than my opinion.



Pros:

Likely cooler environment (although you might not appreciate the added heat in the summer).



Cons:

Harder to find blast air for cooling

The high voltage AC wires are routed through a longer path (65 VAC open circuit)

I’ve never seen this done on certified aircraft or land vehicles. (Maybe not a good reason but something to consider)

If they do go up in smoke you will be breathing that smoke.



Can the forum comment additionally?



Thanks,



Dan

Dan,

I installed B&C Aero regulators. The installation instructions specifically state that they are to be installed on the cockpit side of the firewall, not in the engine compartment.

   Actually, regulators for the B36 and B55

   airplanes are behind co-pilot side of

   instrument panel.



   I recalled having a photo of that installation.

   Dug around in the 'archives'. Found a 640x480

   image captured by the very first digital camera

   I owned . . . paid about $600 for it as I

   recall. It would shoot about 20 images onto

   a 3-1/2" floppy. Anyhow, found the picture.

   The lighting was too poor to produce a useful

   image. Image sensors have come a long way

   baby!



   Don't think there was a driving concern

   for regulator location other than cost

   of ownership. Under the hood was the

   obvious for optimal expense and ease

   of maintenance. Of course, regulators

   nowadays are built right into the alternators.



   Rectifier/regulators are a special breed

   given their internally generated heat.

   So lacking environmental DATA (numbers)

   for a proposed location, one might want

   to err on the side of caution.

   Un impeachable logic: George Carlin asked, "If black boxes

   survive crashes, why don't they make the whole airplane

   out of that stuff?"
