MONOPLANE constucted by Howard Wright for the Scottish Aeroplane Syndicate, and exhibited by their agents, the Aeroplane Supply Co. The machine is of modified Bleriot design, and is characterised by the use of a Santos-Dumont type tail. It has an " A " chassis frame and a combination of wheels and skis for the support of the machine. The engine is carried on a tubular steel framework forming an extension of the main frame, which is made of timber. THE. PETRE MONOPLANE.

Speed of Flight.—30 m.p.h. System of control.—Hinged balancing flaps ; rear elevator and rudder. Price.—;£8oo. THE Petre monoplane is unique in having the propeller situated at the rear, behind the tail, where it is driven by a long hollow shaft from the engine. The engine is situated just behind the trailing edges of the main wings. The pilot's seat is in front of the leading edges of the main wings, being placed right up in the bows of the frame. The frame construction is also uncommon, being entirely of timber, even to the diagonal ties. The longitudinal spars are of L section and the struts of T section, both members being built up of strip wood. Another important characteristic of this machine is the pivoting of the main wings so that the angle of incidence can be altered in flight. Control is effected by a pair of hinged balancing flaps mounted diagonally on the trailing corners of the main wings by an eleva ting plane pivoted to a V frame at the rear of the machine and by a rudder mounted under the elevator. Experiments with a machine having the propeller at the rear ought to be extremely instructive. Although at first sight the position is one that looks impracticable, owing to the well-known difficulty of pushing any long object from behind, yet it does not necessarily follow that this arrangement of the propeller is out of the question on aeroplanes any more than it is on ships. It must be remembered that the propeller, being fixed relatively to the frame, is always thrusting through the centre of gravity. If, however, the thrust is .applied from without —as, for instance, by a man pushing at the tail of the machine—such a force, although it would be of constant direction, would be variable in respect to the centre of gravity of the machine if the machine swerved from its original path.
