I was just reading this
definition of an autogyro in the Wikipedia... it sounds wrong to me but I thought I'd check with the massed wisdom of Pprune before wading in and telling them.
The line in question is:
Helicopters and autogyros use a spinning rotor (a rotary wing) to provide both lift and thrust.
Unless I'm very much mistaken (which is entirely possible), autogyros always have a normal engine-propellor for thrust, the rotor being freewheeling and producing lift only (abnormal flight conditions excepting).
For those that may not be aware, the Wikipedia (and Wikis in general) is a slightly hippy-esque "power to the people" website in which anyone may make corrections or additions to the pages, thus, in theory, tapping into the collective knowledge of the entire planet. Or at least, that part of the entire planet which has internet access.
Would someone like to redraft that paragraph, or shall I have a bash?
