I'm Here.

Hmmm…if I had to guess - you’d be about my grand-son’s age.

Think of that all by yourself did ya?

 

[Darwins Friend]

Wow - excellent retort. Is this how you welcome new members?

 

[dmp]

Wow - excellent retort. Is this how you welcome new members?

Is this how you Introduce yourself? with snide remarks and attempts at age-insults?

 

[Darwins Friend]

Oh lord...it's archangel w/a duplicate account! trying to impress with 'business connections!'

lmao

:teeth:

(Oooh - minus 22 already. What an auspicious beginning.)

 

[Mr. P]

FAA business? Wow, tell us please..

 

[Abbey Normal]

FAA business? Wow, tell us please..

Okay, here's your chance to amaze us, Darwin. Don't blow it now.

 

[Mr. P]

Okay, here's your chance to amaze us, Darwin. Don't blow it now.

I can't wait!

 

[Darwins Friend]

Do you guys know what a radial engine is?

 

[Mr. P]

Do you guys know what a radial engine is?

I do, I do!! Not amazed yet.

 

[Darwins Friend]

I do, I do!! Not amazed yet.

And what makes the radial unique?

 

[Darwins Friend]

hello?

 

[Mr. P]

And what makes the radial unique?

Beside the fact that some are still in service,
or that they’re pretty obsolete, what?

The first part is quite true - the second part is, that for a piston driven power plant - despite being of a relatively ancient design, their horsepower-to-weight ratio is phenomenal and they have few moving components.

And what makes the radial unique?

Either that Harley got its inspiration from it or that the pistons are arranged in a circle around the crankshaft.

Or both.

 

[Darwins Friend]

That is an open question. Only thing is, the motorcycle engine runs on a standard throw crank and a true radial functions like this:

Right. The pistons are arranged in a circle around the crankshaft.

I think I said that.

Yep, but they ain't hangin em on new airframes, are they?
The turbo-prop pretty much won the horsepower thing.

Prefer turbo-fans myself.

Interest in chronological age & airplane engines= antique airplane buff?

 

[Darwins Friend]

Um…well - there are some early twentieth century engines that actually had what we’d consider a regular pinned journal crankshaft configuration that had arrays of cylinders around them - in multi banks of combustion chambers.

The central rotating hub makes the true radial unique.

Perhaps.
