I?m having trouble trying to decide how much inverted capability I should put into my IO-320 powered RV-3B. I plan on flying gentlemen aerobatics, loops, rolls, cuban 8's, hammerheads, slow rolls, and 4+ point rolls. I don?t intend to fly any true -g, but I suspect some of those maneuvers will require 0 to +-1/2g. I understand the inverted oil systems dont really protect the engine from the 0 to +-1/2/g range so I probably wont install a full inverted oil system (dont have the space either). So the question I have is, would an accumulator and the raven air/oil separator suffice? Would just the air oil separator work? I bought the accumulator already so I could test its capacity.
The second problem is on the fuel side. My tanks have the non inverted pick up's and are closed up. Would it be possible to mount a small .5 gallon header tank downstream of the AFP fuel pump? I was thinking about making the tank out of a 4" diameter, 6" long aluminum cylinder. I cold put a check valve on the discharge side of the AFP pump, just before the mini tank. When the plane bumps negative g the engine fuel pump would draw fuel from this mini tank.
Any thoughts?
