I knew there weren’t turbos in 1940 @koolkei , but I just didn’t grasp what the phrase meant. Thanks, @Fayeding_Spray, I’ve never tried that and I just think about people doing it.

1940 has no turbos.

Fuel consumption explanation.

Thank you, @GenJeFT! That helps quite a bit! So should we submit what we want our RPMs to be, for the takeoff and cruise, or is that something you are going to do?

Another question: is there a budget, hour, or quality limit for these engines?

There is no budget or quality limits, cheaper engines score higher in the end.

I will figure out the RPMs when I get the engine.

@GenJeFT Would you be interested in seeing a ‘concept’ engine I came up with for your test, as a comparison to your own personal test platform?

You do not need to provide me with any feedback, it would be purely for your own internal testing.

Sure, it wont be looking at it right away. I just noticed its 1:10 AM.

You’re in my timezone!

Test engine sent, feel free to snicker at the name, it just came to me, as gibberish as it is.

well irl planes from early then have engines that connects directly to the props didn’t they?
so it’s like never surpasses 2500rpm? but of course, geared/stepped down engine are too.
that’s for you to decide.

Keep in mind, these airplane engines are often over 10 Liters, which is beyond our weight limitation.

Done ford SOHC 429 competition won yeah yeah woohoo…sorry I am delirious from work

So if anyone is still interested in this sort of a challenge, I am in the final stages of putting together a flight model that we can use to compare different engines on the same airframe in terms of their performance.

Since there are limitations in terms of engine size in Automation, I have also worked out a way to simulate a reduction gearbox (mostly in terms of the reliability issues they pose) between the engine and the propeller, which will allow us to simulate engines almost as large as we want instead of being limited to low-RPM, direct-drive engines. Also, this simulation will model altitude effects on the engine, both in terms of power as well as the widely varying cooling needs of different flight regimes. Depending on how ambitious I feel, I might even throw in some rudimentary stability calculations as well; the different weight distribution from engine to engine could have a profound effect on how an aircraft handles.

I will provide some tools for contestants to use, most important among them a tool to choose an appropriate propeller for their engine, as well as a calculator for reduction gearboxes, cooling needs, critical altitude (for turbocharged engines; this is the maximum altitude that the engine can produce maximum power) and a few other important things to know.

Cool

I’m still interested :slight_smile: .o/
