NOVEMBER 14, 1918 THE AUSTRIAN BERG SINGLE-SEATER 200 H.P. AUSTRO-DAIMLER ENGINE (Concluded from page 1227.) THE wings of the Berg single-seater are characterised by thesame simplicity—as regards their construction—as that found in the other parts of this machine, a simplicity, be itsaid, which does not result in scamped workmanship and hurried finish, but which bears evidence of careful design, German aeroplanes. Of the merits of the Berg as a :machine we have no information, but from a constructional point of view it shows many features that might with advant-age be studied for cheap and rapid production of commercial aeroplanes after the war. . , _ Fig. 10.—Wing section of the Berg1;single-seater. All the dimensions are in mm. with ease of production always kept in mind. The timberemployed for the wings is of excellent quality, better than that found in the average German machine. The fittings. The wing section of the Berg is somewhat unusual in thatit has a pronounced reflex curvature of its trailing edge (upper camber), while the maximum camber of both upperand lower surface is much farther back than is usually the case in modern wing sections. This is clearly shown in Fig. 10.One result of the reflex curvature of the top camber is to Fig. l'l.—Attachment of front centre-section struts to fuselage of the Berg single-seater. while apparently combining good strength with light weight,are as simple as possible, and welding is resorted to to a much smaller extent than is the case with the majority of fittings in Fig. 12.—Attachment of rear centre-• section ^struts to top longerons on the Berg single-seater. •• provide a^very flexible trailing edge, as the ribs becomevery thin towards the rear.
