Tandem Aeroplanes. A tandem aeroplane may be described as being one in which the surfaces are arranged "fore and aft." The Langley "Aerodrome" was of the tandem monoplane type and consisted of two sets of monoplane wings arranged in tandem. This pioneer machine is shown in Fig. 8, and is the first power driven model to achieve a continuous flight of any length. Instead of two monoplane surfaces, two biplane units or triplane units can be arranged fore and aft in the same manner.
While there have been a number of tandem machines built, they have not come into extensive use. Successful flight was obtained with a full size Langley Aerodrome, and this machine flew with a fair degree of stability. The failure of other tandem machines to make good was due, in the writer's opinion, to poor construction and design rather than to a failure of the tandem principle. The Montgomery glider, famed for its stability, was a tandem type but the machine was never successfully built as a powered machine.
