NOVEMBER 25, 1915. The inter-plane struts are streamline steel tubes tapering towards the ends, where they fit into eyebolts going through the main spars. The method of attaching the bracing cables is identical with that employed on the older machine, and which was illustrated in our issue of April 4th, 1914. A steel shell rests on a fibre pad that is shaped to fit the curvature of the plane. Inside this shell is earned a steel ring to which are attached the turnbuckles of the bracing cables. The two main spars of the wings are placed comparatively close together, giving a rather great amount of unsupported trailing "night" Copyrigrn. The bracing cables of the captured Albatros biplanes are held together by the neat little clips shown in the accompanying sketch. In earlier models of these and other German machines small slotted rubber or fibre balls were used for this purpose. 1/0531 then still further in order to meet the air at a negative angle of incidence. The method of operating the ailerons differs from that usually employed over here in that the crank levers are horizontal, working in a slot in the upper plane. The control cables pass from the drum on the column round pulleys mounted on the floor in front of the " Flight" Copyright. Rudder and elevator crank levers of the Albatros biplane. edge. A short distance behind the main rear spar is another spar, or perhaps it would be more to the point to call it a former since none of the bracing cables are attached to it, forming at its outer portion a support for the aileron hinges. The ailerons, fitted to the top plane only, are given an upward turn towards the tip so as to make their outer ends meet the air at a negative angle of incidence, an arrangement which appears to have been chosen with a view to rendering the ailerons more efficient inasmuch as the one on the high side is already having a depressing effect when in its normal position, increased immediately as soon as the aileron in question is moved upwards, while with the ordinary form the aileron has to move first up to the angle of no lift and footbar to pulleys inside the wings and near the end of the lower plane. Hence the cable passes to the aileron, whilst the return or equalising cable runs to the aileron crank lever. The two halves of the upper plane are attached to a cabane of steel tubes bolted with their lower ends to the upper longitudinals of the body. The main spars of the lower plane are secured to the fuselage in the manner shown in one of the accompanying sketches. The tail planes present no novelties either aero- dynamically or constructionally. There is the usual flat tail plane or stabiliser to which is hinged the divided elevator. On top of the fuselage is a triangular fin, to which is hinged the rudder. The crank levers, operating Side view of the captured Albatros biplane. 919 1 Flight " Copyright.
