JULY 5. 1928 Arado. These are not, however, all represented by actualmachines, some exhibiting photographs and models only. This is the case, for instance, with Dornier, who has a largemahogany "wall", let in, in which are mounted photographs of the four-engined Dornier " Superwal " with " Jupiter "engines that beat several world's records some time ago. A beautifully made metal model of this machine is alsoshown. The Focke-Wulf firm also is at present showing models only, while Rohrbach is represented by a piece ofwing showing the form of constructtion which is typical of this German designer. Arado (G.M.B.H.).—The two-seater biplane exhibitedby this firm is very flattering to Fokker if the old saying is true that " imitation is the sincerest form of flattery." Wedoubt if even Mr. Stephan could distinguish the Arado from one of his own machines. Even the arrangement ofthe shock-absorbing legs is similar and shows the peculiar " herringbone" formation of the rubbers. The machine isfitted with a B.M.W. V.A engine, with the radiator placed under the fuselage. Klemm-Daimler.—One of the small ultra-low powermonoplanes with 20 h.p. Mercedes flat twin engine is shown. As this has been described and illustrated in FLIGHT, it willbe familiar to our readers. It is, however, of interest to learn that recently one of these machines was fitted with oneof the little nine-cylindered, 40 h.p. Salmson radial air- cooled engines, and actually took off with three up in spiteof the fact that the machine was fitted up as a seaplane. Heinkel Flugzeugwerke.—The Heinkel HE.5 exhibitedis similar to the machine which won the seaplane competition at Warnemunde. It is a low-wing monoplane three-seaterof all-wood construction, with three-ply wing covering and flat-sided, flat-bottomed, single-step floats. The engine is aB.M.W. VI, and at a total loaded weight of 2,905 kgs. (6,400 lbs.) the machine is certified by the D.V.L. to have atop speed at sea level of 230 km.-hrs. (143 m.p.h.). Albatros Flugzeugwerke.—The Albatros "ASS" is atwo-seater school machine fitted with B.M.W. engine, and is of " mixed " construction, with welded steel tube fuselageand all-wood wings. It is stated to be a very easy machine to fly, and to have quite a good performance. The radiator isplaced under the fuselage, but, unlike the Arado, it is faired into the bottom and provided with shutters. Junkers-Werke.—Not unnaturally, the Junkers workshave elected to exhibit a machine of the same type as the Bremen," which recently made the flight across the Atlanticfrom Ireland to Labrador. Of the W. 33 type, this machine is, like all Junkers aeroplanes, of all-metal construction, with the corrugated covering tvpical of this firm. Except for the extra large petrol tanks the trans-oceanic machine was a standard W.33. THE ITALIAN SECTION The Italian Air Ministry makes quite an impressive showwith three machines, which in size at least cover, a very wide range. The largest is the Savoia-Marchetti S.55 twin-hullflying-boat of the type in which Pinedo crossed the South and North Atlantic. Fitted with two Isotta-Fraschini" Asso " engines of 500 h.p. each, the S.55 exhibited is a torpedoplane, although not shown with the torpedo in place.The twin hull arrangement lends itself to the carrying of a torpedo centrally. The two hulls each have a gun positionwith Scarff ring in the nose and one in the tail, and " blind spots " should be reduced to a minimum. The particularmachine on view was flown from Sesto Calende on Lake Maggiore and alighted in Paris on the Seine at Suresnes,crossing the Alps en route. The medium-size machine is represented by a Fiat R.22 with 550 h.p. A.22 Fiat engine.This machine is described as a" Strategic Reconnaissance " two-seater, and is a sesqui-plane with rigid strut bracingarranged in the form of a Warren truss. At the lower end of the scale in size, but at the top in speed,is the Macchi M.52 Schneider Cup type on which de Bernardi established a world's record of 512-776 km./h. (318 m.p.h.).The engine is described as a 1,000 h.p. Fiat weighing 400 kg. (880 1b.). CZECHOSLOVAKIA'S CONTRIBUTION An Aero A.23 commercial biplane as used on the CzechState air lines represents the commercial side of the Czecho- slovak aviation, while the military side is represented by anAvia B.H.33 single-seater fighter with Walter " Jupiter " engine. The indented fairings now becoming popular arefitted behind the cylinders of the engine, and the machine has generally a " clean " appearance. It is credited witha top speed of 275 km./h. (170 m.p.h.) maximum, while at 5,000 m. (16,400 ft.), the speed is still as high as 260 km./h.(161 m.p.h.). The machine is of typical Avia construction, with ply-wood covered fuselage. HOLLAND This year the task of representing Holland is executedby the Fokker firm, who exhibit two machines, of which one is a new three-seater reconnaissance monoplane ofrather novel type, and the other a single-seater fighter shown in skeleton. The Fokker method of welded steel [" FLIGHT " Photograph A GENERAL VIEW : In the foreground the Breguet commercial machine. On the left may be seen the portwings of the Levasseur torpedo plane, and farther back, the little Liore & Olivier two-seater flying-boat. 570
