Reply to: Time to bring back propeller driven planes ...

[doodab]

not all propeller planes would work in the cloud of volcanic ash, only piston prop planes because these do not suck in air like the turbo prop planes. Turo prop planes work on exactly the same prinliciple as a jet engine except that the force is used to spin propeller instaed of thrust

Where do they get the air they use to burn the fuel to create the little explosions that move the pistons up and down?

Yay! Bring back Little Nellie!

Or this: http://www.cartercopters.com/

Our primary focus is the slowed-rotor compound aircraft, a vertical takeoff and landing aircraft that uses the rotor for takeoff and landing, and a small, efficient wing for high speed flight, up to 500 mph, all with much less complexity than a tilt-rotor or other vectored thrust vehicle. We successfully demonstrated the slowed rotor concept with the CarterCopter Technology Demonstrator (CCTD), the first and only aircraft to reach mu-1

Oh FFS!!! Did you have to!!!!
I'm not going to sleep tonight.... I'll never get that image out of my head!!

Welcome sir

Are you making much propellerings for very much cheapings?

[Swati]

Thanks for that.

Welcome sir

Back in my 100metres days I'm sure I gained an unfair advantage from start line flatulence.

The gas knocked out the other competitors.

Anyway getting back to propeller aircraft. You could probably guess at how much filtering you'd need in place from a given concentration of dust in the air. E.g. if air were 1 part in 1000 ash, fuel on board 50 tonnes, fuel to air mixture 20 to 1, that's 20*50,000 Kg air used = 1,000,000 kg air per that flight. Dividing by 1000 = 1000 kg dust in the filters. Those are just made up numbers though. Presumably actual dust concentrations would be less. For a turbo or jet engine the dust figures would be staggering.

Like it.

Ryanair has cancelled all of its flights until Wednesday, though aviation experts stressed this is probably just an elaborate tax dodge.

Professor Henry Brubaker, of the Institute for Studies, said: "According to my computer, it would take ages to get to Australia, but, by the same token, it would also take an awfully long time for Australians to get here. Which would, of course, be excellent."

The mash have it spot on again.

So, who's the densest body on this forum?

Body Mass - Threaded
Dense in the head - it's a toss up between MF and Sasguru
