Default WWI Fighter Questions

Greetings. I have been searching for information on the anatomy of WWI fighter aircraft to no avail. Specifically I am wondering about two elements on many fighter aircraft of the Great War. Case in point is the Sopwith Camel. On the outer edge of the starboard wing is a fork-like piece I have no idea of what it is for. Almost like a pitot tube, but I am pretty sure that technology wasn't around yet. Also, near the cockpit is a small propeller which the pilot would see. I am guessing this was something the aviator could use to estimate air speed. Can someone share their knowledge with me on these questions? Thanks so much.

From english wikipedia "Henri Pitot (May 3, 1695 – December 27, 1771) was a French hydraulic engineer and the inventor of the pitot tube."

https://en.wikipedia.org/wiki/Henri_Pitot

If you can read French, here is a more comprehensive wiki page :
https://fr.wikipedia.org/wiki/Henri_Pitot

His invention was at first used to measure the water flow, and was later improved by Henry Darcy, another French engineer, in 1858.


About the small propeller, I think you've got your answer.

Pitot tubes were pretty advanced for the time. The Germans started out with a more primitive solution, an anemometer:





The unit was placed outboard on the port wing, so as not to be influenced by the prop. In that sense, it was conceptually similar to the pitot tube. I don't know if such a setup can be found on an existing aircraft, but it has been modeled as below:





The Germans also resorted to placing a compass outside of the cockpit, this time in an attempt to isolate the device from the engine and other iron-bearing parts around the cockpit area:




Primitive? Absolutely. Clearly, the designers still had some things to figure out at that point!

Another common system was the Etévé speedometer (from Albert Etévé, a French aeronautic engineer) used on several Entente (Allied) aircraft. Here are two of them :


A spring loaded plate is pushed by the relative wind, moving the needle along the scale. Simple but efficient as long as speed is not too high. This kind of speed indicator is still used on some light aircraft.

Thanks for the great information. I had no idea the Pitot tube was already developed. And the device as well. Very interesting.

Yes, I've flown Tiger Moths with them. Lack of accuracy isn't really a problem. Trouble is, when you really need it - on approach to land (and to a far lesser degree on take-off) it's completely out of your line of sight. Add to that the fact that a Tiger can't be accurately trimmed (and some WWI vintage types couldn't be trimmed at all), and it all leaves room for improvement. Part of the charm of old aeroplanes.
