Talk:Propeller

Prior Use of Marine Propellers

I believe this article ignores prior uses of propellers (propelling screws) for marine propulsion. In particular, Bushnell's Turtle, from the US Revolutionary War, utilized a screw propeller. Fulton adopted it for his Nautilus at the start of the 19th century. John Stevens used propelling screws on his early steamboats, predating Fulton's North River Steamboat. Stevens even had a feature for adjusting prop pitch. Tomligon (talk) 22:10, 18 November 2014 (UTC)

• Then that should be added. bd2412 T 03:40, 19 November 2014 (UTC)

Cycloid Propeller

Currently the Cycloid Propeller is mentioned in the header section - and claims of a higher efficiency with NO reference, and never mentioned later in the article. Perhaps should be removed. Whole article is lacking in references Wfoj3 (talk) 14:21, 22 January 2017 (UTC)

Proposal to hive off part of this page

I feel that the mathematical detail in the Propeller theory paragraph lies unhappily with the remainder of the page. I suggest that a simpler summary be retained, while the bulk of the maths is shifted to a separate page named "Propeller theory" '. As it is, one may read through all the figures and still have no idea about the approximate real-world values for slip on, say, a small fast-spinning outboard-motor propeller, or a large slow-turning oil tanker prop.

That sounds reasonable. BD2412 T 16:04, 8 July 2020 (UTC)

The "hiving-off" has been done; my thanks to other editors who helped to polish up the new site. Arrivisto (talk) 09:59, 9 July 2020 (UTC)

Remove coverage of aircraft props?

I'm thinking it might be a good idea to remove coverage of aircraft propellers here, and move any content to Propeller (aeronautics) that's not already covered there. I can at least get started on it, but I would like to get some feedback before making such a large change. Would this be a good idea? 206.204.236.108 (talk) 16:19, 2 August 2023 (UTC)

Coverage of aircraft propellers is minor - it only addresses the history, and serves as a simple introduction to propellers in aircraft. This is appropriate.

The content of this small section should also be available on Propeller (aeronautics) but I’m not in favour of eliminating the section from this article. Dolphin (t) 07:22, 9 November 2023 (UTC)
