Flight 1935-02
A bomber-fighter - the Curtiss BF2C-1 single-seater with 700 h.p. "Cyclone" engine. Note the sliding cockpit cover and retractile undercarriage.
STILL FASTER. A development of the S.73, illustrated in Flight of December 20 last year, this new Savoia-Marchetti S.79, with retractile undercarriage, is reputed to cruise at 217 m.p.h. at 13,000 ft. The engines are Piaggio "Stella IX R.C." of 610 h.p. and the normal load is 6,614 lb. Three S.73S, it will be remembered, have been delivered to S.A.B.E.N.A.

VETERANS BOTH! Mr, C. L. Pashley and one of the Southern Aero Club's lately discarded 504 Ks. Many pilots must regret the passing of the "blip" switch and the "fine adjustment."
NEW ZEALAND'S CHOICE. Sir James Parr, High Commissioner for New Zealand, last week attended Brooklands for a demonstration of one of the twelve "Vildebeests" which have been ordered for coast defence work. Mr. J. Summers, Vickers' chief test pilot, treated Sir James and a large party of visitors to a brilliant display of flying.
Giffard Bay, on the beach at St. Helier, with three of the service "Dragons" in the background. This picture was taken immediately after landing and before the inevitably large crowd collected.
TO AID EMPIRE DEVELOPMENT. The first D.H. "Dragon Rapide" to bear Australian registration letters, the machine illustrated will be used to inspect arrangements for the supply of Shell products in Australia and to collect data applying to their use.
A MAJESTIC CLOUDSCAPE. Taken by a Flight photographer among snow-clouds near Hatfield last week, this impressive picture shows the sixth and last D.H.86 of the fleet ordered by Qantas Empire Airways for the Singapore-Brisbane section of the Empire route.
The controls and special instruments of Giffard Bay. Later machines for Jersey Airways will be fitted with swing-over controls.
STEEL AND STONE: A fine pictorial impression from New York's East River airport. The nose of the Bellanca seaplane silhouetted against Manhattan's skyscrapers is photographically effective, but a trifle disconcerting, perhaps, to the eye of the all-weather pilot!
Stressed - skin monocoques have not put the fabric-covered welded structure entirely "out of business." Note, in this view of the Bellanca's cabin, the long-range tank strapped to the floor.
Bombs are carried partially buried in the lower wing "stubs" and in the fuselage. The great depth of the fuselage and the disposition of the guns are noteworthy.
Strange to British eyes, this Grumman have very high performance. The single-seater has a 700 h.p., two-row "Whirlwind." Note how the undercarriage retracts into the fuselage.
The first D.H. "Dragon" seaplane in Canada.
First of the standard British gears to retract laterally, that of the British Klemm "Eagle" (illustrated in detail on the left) embodies the neat locking device shown in the small sketch on the right.
NEW ZEALAND'S ROYAL VISITOR: The Duke of Gloucester, when he was in New Zealand, made a long flight over some of the famous valleys and lakes in South Island. He is seen here about to embark in the New Zealand Air Force "Puss Moth," which was piloted by Flt. Lt. M. Buckley, at Invercargill Aerodrome.
The catapult retracted and the aircraft being lowered on to it by the crane.
The rigger removing jury struts before a flight
Ready to take off : The "Osprey" at the rear stops of the catapult with engine running and pilot and observer bracing themselves in the cockpits.
AFTER THE FLIGHT: The "Osprey" is taxying back to be hoisted on board.
The catapult extended in both directions, and the Hawker "Osprey" ("Kestrel" engine), heading into the wind. The Forth Bridge is in the background.
Up She comes: The observer has attached the lifting tackle and the crane is raising the aircraft out of the water.
The Northrop being issued to certain attack units of the U.S. Army Air Corps is structurally similar to the bomber version, an example of which was purchased by the British Air Ministry. The Wright Cyclone engine is specified and the maximum speed is about 220 m.p.h.
The addition of the "conservatory" roof above and a bomber's position below somewhat mars the clean lines.
The Northrop's flaps. On the left the split trailing-edge flap is shown closed, and the slotted aileron in the "down" position. On the right the flap is open and the aileron "up." Operation is hydraulic.
Protection is afforded to the crew of the Northrop by sliding roof windows, one or more panels being closed or opened at will.
Running-up the engine: The Northrop 2E outside the hangars at Farnborough
The tail unit: Note the trimming "tabs" on the elevators, and the mass balance which disappears into the tailplane.
The upper member of the cruciform stern piece is twisted in order to reduce yawning due to the rotating slipstream.
The bomber's sighting nacelle, shown retracted and lowered. On the right is a front view, showing the window.
Structural details of the Northrop 2E. The form which the multiple spars and stringers take is shown on the left, while the general "theme" of the fuselage construction is illustrated on the right.
An example of a multi-spar wing, the American Northrop. Although good structurally, this type makes installation of tanks and bombs difficult.
The wheels are carried on cantilever forks from the wing spars.
This sketch indicates the locations of the bombs and machine guns.
The outer wing portions are secured to the centre-section by flanged joints, as shown. On the right are details of the neat steps fitted on the sides of the fuselage; when not in use these steps disappear into the fuselage.
"I'LL STRING ALONG WITH YOU." An impression, seen through a hangar door at Miami, of the U.S. Army attack group from Crockett Field, Galvaston, flying Curtiss A.12 monoplanes.
Of rather "British" appearance - the Douglas four-seater torpedo-bomber (850 h.p. "Twin Wasp" SR 1830-C).
THE SOUTH ATLANTIC "COMET": Salazar, once Black Magic, the "Comet" which has been bought by the Portugese Government and which is to be flown across the South Atlantic by Bleck and Macedo. Mr. Buckingham, of De Havillands', was flying the machine near Hatfield when a Flight photographer took this picture - the first close-up view of a taken from another aeroplane.
THE REPLICA: Mr. C. W. A. Scott with a scale model of the "Comet," presented to him by Flight as a small mark of appreciation of his Melbourne Race success.
ART AND THE AIR: This small reproduction gives some idea of the fine composition and dignity of Norman Wilkinson's painting of the Race-winning "Comet," but it cannot convey the beauty of the colouring. Fine art prints, measuring (without margin) 16 1/2 in. x 20 in., are being offered by the De Havilland Aircraft Co. at ?1 1s.; a few artist's proofs are available at ?3 3s.
On the D.H. "Comet" racing monoplane the wheels retract rearwards into the engine nacelles.
IN INDIA: The Viceroy's Avro 642, Star of India, on the aerodrome at Karachi shortly after its arrival. The Avro Ten, previously used by His Excellency, is now in service with Indian National Airways.
An outstanding new monoplane fighter - the Boeing XF7B-1, with 550 h.p. "Wasp."
Consolidated P-30 Curtiss "Conqueror" Engine
The tapered plan form of the wing can be seen in this view of the "Heck" in the air.
The underside of one wing, showing the flaps in the "down" position, the aileron mass balance, and the recess into which the undercarriage is retracted.
The rear half of the left-hand side of the cabin opens as well as the front half. In the rear cockpit is Mr. B. B. Henderson. The flap is shown slightly lowered.
The wheels of the Hendy "Heck," when retracted, move upward, rearward and slightly backward.
SLOTTED FLAPS: Mr. Henderson achieves a low landing speed on the Hendy "Heck" by means of slotted flaps, the outer portions of which are the ailerons.

The Fairey III F's (Napier "Lion") of No. 45 (Bomber) Squadron flying over the Pyramids while rehearsing for the Middle East Display.
This flying picture shows how the Pobjoy "Niagara" engines have been cleanly faired into the wing and indicates the excellent outlook which the new nose design allows the pilot.
The roomy cabin of the new "Scion"; its proximity to the ground makes entrance and egress very simple for passengers.
Another British gear which retracts longitudinally is that on the Monospar S.T.11.
Strange to British eyes, this Grumman have very high performance. The two-seater has a 700 h.p. "Cyclone". Note how the undercarriage retracts into the fuselage.
LINES OF FORCE The Latecoere boat, Lieut. Paris, on the step during trials at Biscarosse. The extraordinary wave formation was possibly caused by the Latecoere's previous run along the same line.
The Boeing XF6B-1, which has a 700 h.p. "Twin Wasp Junior," <...> transferred from the fighter category to the bomber-fighter class.
200 M.P.H.TRAINERS: The widespread adoption of high-speed monoplanes in the U.S.A. has, it would appear, necessitated the provision of special training equipment. Accordingly, the U.S. Army Air Corps has ordered 35 SEV-3XAR monoplanes of the type shown here. Fitted with a 400 h.p. Wright "Whirlwind," the machine has a maximum speed of 200 m.p.h. and the climb to 12,000 ft. occupies ten minutes.
The Airspeed "Retractor" undercarriage folds longitudinally <...> the wheel exposed. This was the first British retractile undercarriage on a production aircraft, and is now fitted to the <...> and "Viceroy." The two drawings show the method of <...> undercarriage.
The Walraven 2 suggests the "Comet," though actually it was designed earlier.
Efficiency is the keynote of the new Bristol design. The low frontal area is indicated.
Efficiency is the keynote of the new Bristol design. The picture show the split flaps and retractable undercarriage.
The "Snark," photographed on Marshall's aerodrome at Cambridge.
The cabin top is hinged on radius rods, which lift it as it is moved back; the difficulties of sliding the roof in grooves are thus avoided.
These sketches, which are purely diagrammatic, indicate the operation of the De Bruyne system; they should be studied in conjunction with the text.

A remarkable resemblance is borne by the Curtiss XF13C-1 to certain American "private-owner" types.
Ultra-modern in appearance, the Northrop XFT-1 is to be still further developed.
The Sikorsky XSS-2 amphibian fighter scout. The engine is the "Wasp" SD-I, of 550 h.p.
Consolidated XBY-1 (575 h.p. "Hornet" B-1), is an all-metal adaptation of the commercial "Fleetster."
