Flight 1924-06
THE BREGUET XIX, 400 H.P. LORRAINE-DIETRICH ENGINE: This actual machine was used by Lieut. Pelletier d'Oisy on his flight to the East.
Front View of the Breguet XIX, showing mounting Lorraine-Dietrich engine. Note the Andre retractable radiator.
One side of the undercarriage of the Breguet XIX. Note the single strut undercarriage, the streamline axle fairing, and the Artillery type wheel instead of the usual wire-spoke type.
The Henry Potez type XV Observation Biplane, fitted with a 370 h.p. Lorraine-Dietrich engine.
A new Junkers' three-seater: This machine, to which reference was made in FLIGHT recently, is a departure from Junkers' practice in having the wing placed on top instead of low down on the fuselage. The cabin has accommodation for two passengers, and as the engine is a Siemens of 60 h.p. only, the machine is using but 20 h.p. per occupant, which should give very economical running.
COMMERCIAL AVIATION IN AUSTRALIA: The Western Australian Airways, Ltd., Depot at Perth, and some of the machines - Bristol Tourers and Avro.
FLYING TO PRAGUE: On Friday, May 30 Lord Thomson, Secretary of State for Air, General Sir Sefton Brancker, and Mr. Frank Hodges made the flight from London to Prague in a D.H. 50 (240 Siddeley-Puma), Piloted by Captain Broad.Leaving Croydon at 7.30 a.m., the party arrived on the Kbely aerodrome at Prague at 4.40 p.m. Mr. Hodges was on his way to Vienna, while Lord Thomson and General Sir Sefton Brancker were attending the opening by Professor Masaryk, President of the Czechoslovak Republic, of the Third International Aero Exhibition in Prague. Our photograph shows the three air travellers in merry mood a moment before the departure. Above the luggage is being loaded on board.
BRITAIN'S AIR MINISTER AT PRAGUE: Our photograph shows Lord Thomson with several notabilities who met him on his arrival at the Kbely aerodrome. Inset shows the D.H.50 landing on the Prague aerodrome, carrying Lord Thomson, General Sir Sefton Brancker, and Mr. Frank Hodges. The flight from Croydon to Prague was accomplished in a little under nine hours.
A NEW SUPERMARINE AMPHIBIAN FOR SPAIN: The engine is a Rolls-Royce "Eagle IX." The machine carries pilot, gunner, and observer forward. A camera is fixed in the interior of the hull, where also bombs are carried.
A CORNER OF THE BRITISH EXHIBIT AT PRAGUE: In the foreground the Armstrong-Whitworth "Siskin," with Siddeley "Jaguar" engine.
The "Avia" B.H.3.is a single-seater scout, fitted with the new Walter 220 h.p. engine. The radiator is placed under the fuselage.
The "Avia" B.H.7 parasol monoplane single-seater fighter. The engine is a 300 h.p. Hispano-Suiza. Note the radiators placed between the chassis struts.
One of the chassis-strut radiators of the "Avia" B.H.17. These radiators are manufactured by the "Avia" company. Shutters for varying the cooling are mounted on the front struts, but are not in place in the photograph.
Details of wing construction of the B.H.17 biplane. The single interplane strut is braced by large turnbuckles at top and bottom, as indicated in the diagrams. Spars and ribs are of similar construction to that used in other "Avia" machines.
Undercarriage and retractable radiator of the "Avia" B.H.19. This machine is a low-wing single-seater monoplane fighter with 300 h.p. Hispano-Suiza engine.

THE FOKKER T-III MONOPLANE: The machine shown above is a three-seater low-wing cantilever monoplane, which is fitted with either a 450 h.p. Napier "Lion" or a 360 h.p. Rolls-Royce "Eagle." Several af this type have been - or are being - constructed for the Portuguese Government, and it was the type of machine which Admiral Continho and Commdr.

The Dietrich-Gobiet "D.P.IIa" is a two-seater biplane with Siemens radial engine.
CZECHO-SLOVAK CONCEPTION OF COMMERCIAL AEROPLANES: These three scale models represent designs either actually in course of construction or contemplated by the Military Aircraft Factory, to the designs of Ingenieur Smolik. 1 shows the "S.15," with four Hispano-Suiza engines placed in tandem in the wings. The propeller efficiency of the pusher screws aft of such a deep wing seems a somewhat doubtful quantity. In 2 is shown the model of a three-engined machine, in which the tractor engine in the fuselage is a Napier "Lion," while the two pushers are B.M.W. engines of 220 h.p. each. 3 shows a seven-engined design, but this has, we believe, been abandoned as being too ambitious.
At the Pageant: THE DE HAVILLAND "DORMOUSE": A recent "hush-hush" two-seater fighter biplane.
