MAY 2, 1914, Edited by V. E. Aero Models at Olympia. Mr. W. H. Nosworthy's Exhibits. AMONGST the eight classes under which models could be exhibited at Olympia was one for models embodying new designs applicable to full-sized machines, a prize of ^3 being awarded, at the discretion of the judges, for the model which embodied the most original and practicable ideas. This prize was awarded to one of Mr. Nosworthy's several exhibits, viz., No. 206, a model embodying several new ideas, and which is described in detail below. All Mr. Nosworthy's JOHNSON, M.A. working on a shaft which is rigidly connected to the fuselage. The two wheels to be operated by the aviator are movable only when desired, thus preventing accidents by slipping on the rudder bar, or falling over when holding the ordinary control, both of which we know have caused more than one fatal accident. The constant strain on the aviator is thus done away with, as the wheels may be set at any angle at will. The wings are connected to this control, and are movable, either together or separately, to increase or diminish the angle of incidence ; this can be done as minutely as may be desired, or to the full extent of the rise and fall. The rear portion of the machine consists of a stabilising tail, which, when moved in conjunction with the wings (this is done by the stabiliser being connected to the above control), provides for the turning movements and also assists in a slow descent. The propeller is driven from the centre of gravity through a gap in the wings, which gap, when alighting with the propeller stopped, acts similarly to a para chute. A pair of floating wheels give considerable support to a central float. These wheels are con nected or released from the engine at will, and when connected are rotated in the water, thus giving Mr. W. H. Nosworthy's dihedral biplane model, fitted with dihedral angled floats. The collapsible anchor buckets on the Nosworthy model. At top, starting to run out, and below, in the water. exhibits, which have been previously referred to in this section, were on sound practical lines, and there is no doubt his exhibits well deserved the reward they received ; as to which was the best is, of course, a matter of individual opinion, but theie can be no question as to the merits of his exhibits as a whole. With these few prelimi nary remarks, we pass on to consider them individually more in detail, taking first the particular exhibit for which the prize was more especially awarded. Variable Angle Monoplane Amphibian. In this model both wings are swivelled on the horizontal, and are moved by specially devised bevelled wheels and a worm gear, all greater speed when rising. They are pneumatic tyred and sprung lor alighting on land. Referring to the above description, kindly supplied us by the in ventor, the model exhibited was not a practical flying model, and if we understood Mr. Nosworthy correctly, he has not tested his ideas in actual practice; we refer more especially to the gap and propeller position and the floating wheels. So far as we are aware, no flying model has been constructed with the gap and propeller position as here advocated. But the experi ment is one well worth trying by a practical aeromodellist, and its effect on the longitudinal stability of the machine carefully noted. Should any reader care to try the experiment, and send us along the "s. Showing how the angle of Inclination of the floats can be altered at the will of the flyer on the Nosworthy model.
