Hi all, i found these links dedicated to Sir Hiram Maxims Flying Machine, there was a topic a while ago that touched on this it seems that the maxim machine was more succesfull then i had previously believed....
I understand that some doubt has been expressed about the ability of the flying surfaces on Maxim's amachine to allow the pilot to control it. It was a double bind - the machine had to be very large to lift the engine but this would have meant very large control surfaces which would make it difficult for the pilot to manage
Hi Centurion, I think this machine was intended as a test bed and to modify the design perhaps to incorperate controls of some kind in this time of trial and error, when it was understood what what was needed..... however maxim understood enough about the principles to include the minimum necesary in the initial design , wings with dihedral, elevators and a correctly placed centre of gravity/lift the rails effectivly keeping the machine in a staight line, although i dont personally think that they were necesary, I think of it more as a hang glider with an engine, moving the centre of gravity or changing the prop speeds would cause the aircraft to change direction but control would no dought be clumsy and sluggish a certain hieght would also be neccesary since tipping the wings at all would reduce lift causing a loss of hieght...the size was neccesary to lift the heavy engine and three man crew... I also think the elevators are not really far enough apart and the slow speed would'nt help with control here, one reason why you need to have large control surfaces these would not be a problem for the pilot as long as part of the surface is forward of the hinge... all in all a machine for a very calm day.....It must have been amazing to watch in action....probably rather like the "Gossamer Albatros"....it seems to have flown several times in a modified form.....
Maxim apparently intended for the machine to be steered by varying power to each propellor, and he anticipated the difficulty of controlling the pitch of the machine by fitting his fore and aft elevators on long arms to obtain greater leverage, whilst rolling was to have been automatically dampened by the noticeable dihedral. Whether or not it would have been a practical aeroplane is hard to say. Such a large machine may have been difficult to control, but on the other hand, might have been less sensitive to adverse gusts and air currents than a smaller lighter craft. But Maxim was very methodical in his work, and far from the 'chauffeur' many writers have made him out to be. No less an authority than Bill Gunston, the aviation writer and a vastly experienced pilot, writes of Maxim in highly respectful tones in 'Giants of the Sky'.
I've always been a big fan of the Maxim machine, such a daring project and (perhaps) so tantalisingly close to success. There's a beautiful large model in the Science Museum in Kensington, I think it was actually built around the time of the real thing, and one of the engines is also displayed there.
Tangentially, in the original serialisation of H G Wells's 'The War of the Worlds' (Pearson's Magazine, 1897), the artist who illustrated it (Warwick Goble) based the Martian flying machine explicitly on Maxim's machine, whilst in an earlier Wells short story, 'The Argonauts of the Air' (1895), his pioneering aviator, Monson, was based on Maxim (though Monson's first flight comes to a sticker end than Maxim's as his machine crashes fatally and spectacularly into the Royal College of Science in London).
A book by the great man "Artificial and natural flight "(1908) by Hiram.S.Maxim details everything and can be found here, with many photos and drawings...
that's another great lead Ironsides! And tantalising, for modelling or even building a 1:1 scale. All reminds me very much to Panamarenko, famous Belgian artist, working for decades on all sorts of flying contraptions. Beauty counts, if they ever can fly is just a part of the mystery. See one in a museum and your fingers start to itch. Sorry for digressing..
