Will that thing move the trailer the way you have it setup there if you revved it high enough?

[fishsponge]

@partyman6666 it's not actually my engine or trailer... i was just filming it, but my understanding is that the propeller on the front is there to simply give the engine something to push against.

it creates a bit of wind, but it is not designed to actually move stuff around - i think it's too small and the angles of the blades are not designed for that. I could be wrong though...

Must be an aero engine rally!

[fishsponge]

@Poopingbotham it wasn't an aero engine rally, as it happens!

it was the Corvette Club UK's National Show back in 2008, would you believe! :-)

[fishsponge]

@gymover indeed... the trailer isn't moving, so any engine would give zero MPG :-)

You can see that propeller wouldn't be the type you fly with, I reckon its just a fan to keep it cool not an actual propeller which gives thrust

[alanmeires]

dose this thing do any thing apart from make alot of noise?

[WEITESTAL]

@skeligandrew Yes certainly the original airscrew was about 4 meters in diameter!

@predator5723 Hellcat and P-47 Thunderbolt I reckon

[fiddlinjd]

guys, seriously... newtons basic laws. if you chock it and constrain it in one direction, it will be unable to move in the other direction. for further study, i suggest reading into "degrees of freedom" in the kinematics field of study.

that prop is not only modified, it is not configured to produce any usable thrust. its primary purpose now is to fan the engine for cooling as well as provide some kind of load on the engine.

[predator5723]

what plane used that engine?...

@goodkarma33 Been done! My family builds Airboats. Nowadays, most use automotive engines, due to availability of parts and gasoline. In the old days, most were powered by aircraft engines, both radial and in-line designs, but the price / availability of aviation grade fuel (avgas) and repair parts went through the roof!
