Douglas did make stationary engines from WW1 onwards, that bore a passing resemblance to those they fitted to their motorcycles. Sometimes they had special crankcases, dedicated for the purpose that could look like that shown. Having said that, those cylinders and valve pockets, and the bridge piece holding the cylinder assembly down, do not look like anything I have seen on a Douglas engine. It seems clear it did start out as someone's stationary engine, with the built in features for forced fan cooling. During the era this engine appears to belong to, a Douglas stationary engine would be based on a 2-3/4hp or a 4hp engine. So I would say Douglas negativa, sino yo no sabe cuáles es.

What did the Dryad aero engine look like?

I assume it has a gearbox et al out of sight,  didnt Rover make something like that in the 20's?

Oh, nothing like that. The Dryad was a high camshaft ohv unit, with a large twin magneto drive housing across the top.

Hi Dave

Sorry to drag up an old tread.

The engine is a Stuart Turner, made for the War Office for front line radio equipment.
I have one, and there is about 14 known, I have a copy of the registry.

Kind Regards

Stephen

Josep is probably no longer watching the thread, but at least we now have a definitive answer.

Thanks Stephen!

Sorry didn’t think to post it as it was such an old thread.

The engine is a Stuart Turner WD (War Department) or Flat Twin Air Cooled as it is better known.
The Stuart Turner Flat Twin came into existence when the War Office approached Stuart Turner and seven other companies in 1923, for a light -weight generator set that could be carried into forward operating positions on the back of pack mules. The War Office set stringent criteria that needed to be fulfilled. Stuart Turner was asked to build two engines for trials. The engine that was produced was the only engine to perform as needed while adhering to the criteria. The engine which Stuart Turner designed and entered was a Small Flat Twin Side Valve air-cooled four stroke supplied with 300 Watt generator, oil pump fitted and the sump was sealed so that the engine would not be affected by which position it was carried in, and was extremely light in weight.

The brief was that the whole set should weigh no more than 84 lbs (38 kilos) as it was intended for forward radio positions in difficult terrain & would be carried on a pack mule. It must be unaffected by the position in which it was carried, be capable of operating in any temperature from freezing to 140oF and govern its speed to within 5%. There were other conditions too, but these are the salient details.

They produce 1HP at 1760RPM, so not the most powerful of things, I wouldn’t have thought the car would have been much of a speed machine!

At the moment there is 14 known, only about 2 are a complete set, most are engine only.

Im just after the Marconi Douglas to go with it  :wink:

Cheers, Steve
