ORIGINAL: Taurus Flyer
Gents,
(Duane read first before answer, of course I know what finish means!)
We did write about the fuel tank before and here they are!
Howard Bonner and the Smog Hog and Daniel Bernoulli the Dutchman the
“Golden Team”.
See picture 1 and 2:
The air inlet tube on the same level as the spray bar gives you a constant fuel pressure in normal horizontal flight as long as the level is above the air inlet in the tank!
On the Smog Hog you even could rotate the tank to adjust!!
The lower air pressure above the fuel level is the same as the hydrostatic (fuelstatic?) pressure of the fuel, so compensation!!
Look to the control liners but the RC-pilots also knew in the past.

Gents,
When speaking about the fuel tanks for the Taurus I did show some fuel tank lay-outs and the result on the pressure for the spray-bar in the carb.
When we only speaking about unpressurized fuel tanks, so no connection with the crankcase or exhaust on any place we can go back further in time, Italia.
Evangelista Torricelli, 1608 – 1647 see the picture.1
Evangelista did show us, you could have a vacuum above liquid, just as we see in the fuel tank of the Smog Hog.
This is the most important physical law of all the unpressurized fuel tank systems.
When pressurized (but also unpressurized in acrobat flying and control line), Bernoulli but also Pascal becomes again important
Picture 2 shows us there is fuel flow without “sucking” of the carb (rich) when we do not have the vacuum and the fuel level is too high!
Picture 3 shows us the max vacuum that’s possible on our globe but that’s not interesting.
In my process of redesign and reconstruction I do account with the situation also Ed did know this law of Evangelista Torricelli of course.
Go take a look on the Internet for this if you did not know him yet,
Torricelli the Italian Vacuum Inventor,
Supertigre,
is from the same country!
I think all these physical processes around our Glow Plug engines makes the traditional contest flying most interesting of all because also our inventors as Ed Kazmirski and Howard Bonner are showing us they did know these laws and processes also.
Most important to know the right fueltank configuration does give you a very stable fuel/air ratio during the period the airinlet in the tank isn’t above the fuel level.
Of course this is theoretical and we always have to do with vibrations and movement of fuel during flight but, why not use what Evangelista did tell us?
It can make you win the game! See picture 4.
If we do not show them frequently, all these important persons, I think they are all forgotten in a short time and with them the real history, performances, wins and also they did invent for us in the past.
