Blackburn F.2 Lincock
В 1928 году в инициативном порядке компания "Blackburn" построила свой второй одноместный истребитель - Blackburn F.2. Самолет представлял собой легкий биплан деревянной конструкции, оснащенный мотором воздушного охлаждения Armstrong Siddeley Lynx IVC мощностью
240л.с.(179 кВт). Фюзеляж схемы полумонокок был обшит фанерой, все остальные поверхности - полотном. Самолет был впервые публично представлен в мае 1928 года под обозначением F.2 Lincock I. В последующий год Lincock неоднократно принимал участие в различных показах, получал хорошие отзывы, но заказов на серийное производство так и не последовало.
Машиной заинтересовалось правительство Канады, но ему требовался самолет металлической конструкции. Специально под этот запрос был построен F.2A Lincock II, оснащенный двигателем Lynx IV мощностью 255 л. с. (190 кВт) с редуктором. Этот самолет проходил испытания в Канаде, но затем был возвращен фирме.
Было построено пять истребителей F.2D Lincock III: по два для Японии и Китая и один остался в собственности "Blackburn". Lincock III был вооружен парой пулеметов, стрелявших через плоскость, ометаемую винтом. В результате интереса, проявленного правительством Италии, фирма "Piaggio" приобрела лицензию на постройку двухместного пилотажного варианта Lincock. Был построен лишь один самолет этого типа, получивший обозначение Piaggio P.11.

British Exhibits At The Berlin Aero Show 1928
THE BLACKBURN AEROPLANE CO., LTD.
The Blackburn "Lincock" with the Armstrong-Siddeley "Lynx" 200 h.p. engine is exhibited in model form as a sporting machine for single- or two-seater purposes. It can be produced cheaply and is of high performance. It carries the same fuel and load of higher powered machines in the same class. Its. manoeuvrability is excellent. In performance it is the equal of higher-powered types in its class without supercharged engines. One of these machines, it will be remembered, took part in the last King's Cup Air Race.

BRITISH AIRCRAFT AT OLYMPIA
BLACKBURN AEROPLANE & MOTOR CO., LTD.
IN addition to the machines exhibited on their own stand, the Blackburn Aeroplane and Motor Co. will have on view two "Bluebirds." These, however, will be exhibited on the stand of Auto Auctions, Ltd., who have been appointed sole world concessionnaires for this type of light 'plane. The descriptions of the "Bluebirds" will, however, be found at the end of the notes dealing with the aircraft shown on the Blackburn stand, and readers are reminded that prospective purchasers should apply to Auto Auctions, Ltd., for more detailed information than can be given in the limited space we have available.
On the Blackburn stand itself four complete machines will be exhibited, or rather three complete machines and one large flying-boat hull, for the wings of which there is not sufficient room at Olympia. The four machines are: The hull of the "Nile" commercial flying-boat, a "Ripon II" torpedo, bomber or reconnaissance biplane, the "Lincock" light single-seater fighter, and the "Nautilus" reconnaissance deck-landing fighter.
The latest type of Blackburn "Lincock" light single-seater fighter is the all-metal version of the previous wooden prototype. Originally designed as a high-performance single-seater fighter with relatively low power, the "Lincock" is now available with a number of alternative power units and, according to the engine fitted, possesses qualities which make it suitable for the additional alternative duties of training, fast mail-carrying, forest fire patrol work, &c. In spite of its relatively low power, the "Lincock" has a performance which is not very far short of that of many single-seater fighters of nearly twice the power. It is, moreover, a very economical machine both as regards first cost and maintenance.
The fuselage of the metal "Lincock" is composed of three detachable units: the engine mounting, the centre and cockpit structure, and the rear fuselage. The fuselage structure is entirely of steel tubes, all diagonal bracing being by struts instead of tierods. No welding is used, the joints between longerons and struts being steel plate fittings with bolts through the longerons and tubular rivets through the struts. Below the centre structure is a vee of steel tubes, the apex of which forms the attachment for the lower wings and undercarriage.
The biplane wings of the all-metal "Lincock" have main spars of special drawn sections of high-tensile steel strip, and ribs of duralumin. The upper wing is built as one complete unit, and the lower wing is in two halves attached at the centre to the vee already mentioned.
An undercarriage of the divided type is fitted, each chassis half consisting of bent axle, radius rod and telescopic leg. Wheel brakes are fitted. A feature of the design is that the lower wing, although in two halves, does not interfere with the undercarriage when the wing has to be dismantled.
The engine, an Armstrong-Siddeley geared "Lynx" in the exhibition machine, is so mounted as to be completely accessible for all adjustments, and the entire engine may readily be changed. The petrol is carried in two tanks, one inside the' fuselage and the other in the centre of the top plane. The supply from both to the carburettor is by gravity.
The pilot's cockpit is, in spite of the small size of the machine, comparatively roomy, and contains the usual flying controls, instruments, etc. The seat is of the parachute pack type, and when the "Lincock" is equipped as fighter the armament consists of two machine guns with interrupter gear. Provision can be made for carrying wireless.
The Blackburn "Lincock" has the following dimensions: Length, 19 ft. 6 in.; wing span, 22 ft. 6 in.; chord, 4 ft.; wing area, 170 sq. ft. The gross weight is 2,000 lbs. and the load carried 700 lbs.
With the Armstrong-Siddeley geared "Lynx" the performance of the "Lincock" is as follows: Full speed, 155 m.p.h.; cruising speed, 130 m.p.h.; landing speed, 60 m.p.h. The initial rate of climb is remarkably good for the power, at 1,450 ft./min. The range is 390 miles, the service ceiling 20,000 ft., and the absolute ceiling 22,000 ft. The wing loading is 11-3 lbs./sq. ft., and the power loading 8-9 lbs./h.p.

THE NEW ALL-METAL "LINCOCK”
THE latest version of this fascinating little machine has just been put through its first test flights, which have been very satisfactory, by Capt. Blake, and in its new form it looks a picture of efficiency.
The fuselage is made in three detachable units - engine mounting, centre portion, and rear fuselage. The engine mounting is built up from duralumin plate, while the fuselage consists of four steel-tube longerons with rigid steel-tube bracing. The bracing strut joints are fixed with bolts through the longerons and tubular rivets through the struts.
The wings are also of all-metal construction with spars built up from high-tension steel strip sections and duralumin ribs. The tail units are normal monoplane type and of the same construction as the wings. The chassis, which, as can be seen from the photo, is the divided axle type, and is arranged so that the bottom planes can be removed without in any way disturbing the oleo pneumatic spring leg. The tail skid is sprung with a helical spring inside the sternpost, and brakes are fitted to the wheels.
Built primarily as an economical single-seat fighter, the Lincock has ample provision for full-service equipment, including two fixed machine guns and wireless gear, and in spite of its small size, the cockpit is very roomy and comfortable.
The engine fitted to this model is the geared Lynx (225 h.p.), but any model of this engine can be fitted. The fuel supply is arranged with gravity feed and is carried in two tanks, one in the centre section of the top wing and the other in the fuselage, with the oil tank close to it, and both these latter are behind the fireproof bulkhead.
Dimensions :- Span, 22 ft. 6 in. (6-8 m.); length, 19 ft. 6 in. (5-9 m.); height, 7 ft. 10 in. (2-38 m.); chord, 4 ft. (1-2 m.); wing area, 170 sq. ft. (15-7 sq. m.); gross weight, 2,000 lbs. (907 kgs.); total load, 700 lbs. (317-5 kgs.).
Estimated performance :- Top speed, 155 m.p.h. (249 kms./hr); cruising speed, 130 m.p.h. (209 kms./hr.); landing speed, 60 m.p.h. (96-5 kms./hr.); initial climb, 1,450 ft./min. (442 m./min); service ceiling, 20,000 ft. (6,100 m.); absolute ceiling, 22,000 ft. (6,710 m.); range, 390 miles (627 kms.); wing loading, 11-3 lbs./sq. ft. (55 kgs./sq. m.); power loading, 8-9 lbs./h.p. (3-85 kgs./h.p.).
INTRODUCING A NEW CLASS IN FIGHTERS: The Blackburn "Lincock" with Armstrong-Siddeley "Lynx" engine is of a type known as a "light fighter." It was demonstrated during the visit to Brough by Squadron-Leader Jack Noakes, who did some amazing "crazy-flying" on it.
AIRCRAFT IN THE KING'S CUP: Blackburn "Lincock" (180-h.p. Siddeley "Lynx").
THE BLACKBURN "LINCOCK": A light single-seater fighter, fitted with Armstrong-Siddeley "Lynx" engine. Note the "helmets" over the cylinders. The figure of the pilot (Capt. Blake) standing next to the machine gives a good idea of the smallness of the "Lincock."
THE KING'S CUP AND SIDDELEY TROPHY: Some competitors starting from Hendon on the first stage. Sqdn.-Ldr. J. Noakes gets away on the Blackburn "Lincock" (Armstrong-Siddeley "Lynx").
The little Blackburn "Lincock" with Armstrong-Siddeley "Lynx" engine, piloted by Sqdr.-Ldr. Jack Noakes. This is a new class of machine, known as a "light fighter."
A LIGHT FIGHTER WITH HIGH PERFORMANCE: The Blackburn "Lincock," Armstrong-Siddeley "Lynx" engine, in flight, piloted by Capt. Blake. In spite of the relatively low power the machine has an impressive performance. It is also reported to be exceptionally nice to fly.
"Helmets" gave a good aerodynamic improvement, but bad cooling. The Lynx-engined Blackburn Lincock was one type equipped experimentally.
A DIFFICULT COLOUR SCHEME: The Blackburn Lincock-Lynx is painted in black and lemon stripes, which do not photograph well. Captain Blake's demonstration of aerobatics on this machine was a very wonderful spectacle.
THE BLACKBURN "LINCOCK": As a machine for advanced training, this little single-seater would be difficult to improve upon. It is extremely manoeuvrable. The engine is a "Lynx."
Cobham used two Lincocks for radio controlled aerobatic displays. Seen here is G-AALH, fitted with a 270 h.p. Armstrong Siddeley Lynx Major engine. It flew with No 1 Display, doped mauve overall for the 1934 season.
DESIGNED AS a compact single-seat light fighter with a fabric-covered all-metal airframe, Blackburn Lincock Mk II G-AALH was built at Brough and was awarded its C of A on February 28, 1930. It had a 255 h.p. Armstrong Siddeley geared Lynx IV radial engine. In 1930 it was evaluated by the Royal Canadian Air Force at Camp Borden, but although it was much liked by pilots the type was not adopted because it was not a first-line fighter and there was no need for a transitional aircraft from trainers to fighters. Along with the sole Lincock III, G-ABFK, it was used by Alan Cobham’s National Aviation Day Display organisation in 1933-34 for the “radio controlled” aerobatics act, powered by a 270 h.p. Lynx Major, but was dismantled in March 1935. It is probably seen here in the mauve colour scheme applied during the winter of 1933-34.
Lincock III можно легко отличить от других машин этого семейства по прямой передней кромке киля. Было построено всего пять самолетов этого типа.

BLACKBURN LINCOCK. Photographed at Dagenham Park in April 1934 was this special Blackburn Lincock - originally intended as a single-seat interceptor - note the machine-gun groove on the fuselage immediately behind the weatherproof covering over the exposed Armstrong Siddeley Lynx of 215 h.p.
Painted a violent purple hue overall, G-AALH was for a time part of the famous "Air Circus" which toured the United Kingdom in the 1930s under the leadership of (Sir) Alan Cobham who, as a pioneer o(many Empire air routes, is perhaps best known today as the founder of Flight Refuelling Ltd.
