Eingebaut im Stahlwerk.
Installed in a Steelwork.
This was made in the 1960s, as part of the Triang Hornby 'Battle Space' range of models.
It's an unusual model train item, as it is a stand alone vehicle that can't be joined to anything else. The motor also powers the propeller at the back, not the wheels.
It's also a health & safety nightmare for smaller children! This thing can fly round the track and anyone at ground level taking a look it is liable to get a poke in the eye. A spinning propeller at the back is also not great for little fingers.
Having said that, it's a real curiosity and boxed ones are becoming quite rare.
"A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral, that, when rotated, ... transforms rotational power into linear thrust" (Wikipedia).
Ignore the Exif data. This image was taken with the 35mm Mitakon Speedmaster manual lens at F0.95.
Neglected old boat next to the decaying jetty in Karavostasi, which still remains under Turkish occupation since 1974.
Aircraft Propeller this is attached to a Beech twin engine WW2 bomber trainer found in North Carolina.
Despite appearances, the cockpit section of this aircraft was constructed largely of wood! During WW2, the de Havilland company devised methods of using plywood and balsa to form light and strong structures suitable for aircraft manufacture, the most famous example being the Mosquito. After the war, as the company workforce still had the skills to work with wood they continued using it (at least to some extent) in the earliest jet aircraft. Early jet engines lost power through the use of long jet pipes, so for the dH Vampire family of designs, the tail plane was extended out on booms either side of the exhaust. Other early jet aircraft designs of the era split the exhaust laterally and exited it just behind the wings on either side, continuing the fuselage back to carry the tailplane (eg the Hawker Sea Hawk). An advantage of jets was that the high ground clearance for large propellers was no longer needed, meaning the undercarriage legs could be shortened, reducing weight and making servicing easier. The pilot's forward visibility was greatly improved by the use of tricycle undercarriage making ground handling much safer.
Vampires first flew in 1943, entered service in 1945 and were finally retired from the RAF in 1955. Over 3,000 of various marks were built, serving in the air forces of more than a dozen countries.

Reminded me of a propeller on a ship going through the water at high speed. Created with different shapes of light. No photo shop, and is one single image taken over the span of 195 seconds using some light painting brushes instead of regular paint.

Propeller sundial.
This sundial was constructed by Martin Gutoski. The bent propeller was donated by the owner of a small aircraft that crashed. The arms of the sundial are cut from saddles used to support the Trans-Alaska oil pipeline. The shadow of the propeller centers over the hour of the day.
Here is a mystery object. No doubt someone out there will be able to tell us what it is. One thing I think we can be certain of, it is not a ship's propeller. It would be a large ship in any case, but the blades are all the wrong shape for that. Some kind of fan?
My best guess would be a wind turbine of some sort. Perhaps one that sits on top of a building. There was a government building in Hobart several years ago that had a small wind turbine array on its roof. But being in the Roaring 40s, these turbines failed, and nearly blew onto the street below. Perhaps this is one of those. I really don't know.
