MARCH 6,. 1.924 A NEW IDEA IN GLIDERS A German "Sailplane" of Unorthodox Design •ONE of the most extraordinary gliders ever built was designed Zeitschrift fur Flugtechmk und Motorluftschiffahrt, otherwise ^nd constructed in Germany towards the end of 1922, and " ZFM," contains an article by R. Platz, and some illustrations of the " Sailplane." In an editorial note it is stated that flown in February of last year. It is not, however, until now that any information relating to this machine has been published. The January 26 issue of our German contemporary the article was sent to " ZFM " as long ago as February, 1923, but that, according to the wish of the author, it has not A GERMAN " SAILPLANE " : The photograph on the left shows a man transporting the folded machine on a bicycle.

Some of the illustrations from " ZFM " are published herewith, and we have further pre pared a set of diagrammatic side and front elevations and plan so as to show the general arrangement a little better than does the photograph. The author of the article states that what gave him the idea for the " sailplane " was the memory of past experience with a sloop-rigged sailing boat, in which, by suitably trimming the sails, it was possible to steer without using the rudder, simply by hauling in or paying out the jib sheet. He con ceived the idea that it should be possible to apply the same principle to a glider, and he furthermore set himself the conditions that the machine should cost no more than an ordinary bicycle, should be capable of being transported by one man, and should be so constructed as to enable it to be folded into a space sufficiently small to make it possible for A GERMAN " SAILPLANE" : Plan, side and front elevations. These are of a purely diagrammatic character, and not necessarily to scale. They were drawn to assist in forming a clearer idea of the general arrangement of the machine. 129 D
