Forbes and Arnold Monoplane
Victor F. Forbes and Arthur J. Arnold built their single-seat tractor monoplane at Leigh-on-Sea, Essex, in 1909. It was of extremely unconventional design, intended to secure natural stability, as described in their Patent No. 20846 of 1909. Although successful flights were claimed with models of this design, there is no record of any full-scale flying being accomplished. Span, 16 ft. Length, 24 ft. Height, 10 ft. Wing area, 350 sq. ft. Weight loaded, 450 lb.
Flight, November 11, 1911.
Having read with considerable interest the letters of Harold Kelk and Will H. Booth, and having ourselves, for a long time, been experimenting on the lines adopted by these gentlemen, we send you photographs (reproduced herewith) of our full-size machine, which we have built as a result of our successful experiments with models.
We patented it in 1909. The patent No. is 20846, and we append particulars of size which, with the photograph now sent, will enable you to see the principles upon which we have built:-Length, 24 ft.; width, 16 ft.; height, 10 ft.; surface, 350 ft.; weight with pilot, 450 lbs.
The principal objects we studied to accomplish in creating our machine were - 1st, safety; 2nd, natural stability; 3rd, simplicity in steering, elevating, &c.; 4th, small motive power; finally, low cost of building. The lifting surface is so arranged that, in the event of the engine stopping, the machine will descend in a series of glides, and settle on a level base.
It is seeing that our ideas are apparently coming into vogue that it seems advisable to explain our position.
Leigh-on-Sea. VICTOR F. FORBES, ARTHUR J. ARNOLD.
