Armstrong Whitworth Siskin
Изначально известный как Siddeley Deasy S.R.2 Siskin, самолет был построен в 1919 году дочерним предприятием "Armstrong Whitworth". Самолет проектировался с прицелом на то, чтобы стать основным истребителем британских ВВС с середины 1920-х годов. Машина проектировалась
под звездообразный мотор мощностью 300 л.с создававшийся вначале в Фарнборо на 8-м авиазаводе, а потом - специалистами фирмы "Siddeley Deasy". Однако из-за того, что компания больше времени уделяла программе двигателя Puma, первый полет S. R.2 выполнил с 320-сильным мотором ABC Dragonfly. Хотя аппарат показал хорошие летные характеристики, двигатель работал ненадежно, что потребовало установки мотора Armstrong Siddeley Jaguar мощностью 325 л.с. Первый из трех прототипов истребителя Siskin поднялся в воздух в марте 1921 года уже под маркой "Armstrong Whitworth".
Новая политика Министерства авиации, которое решило заказывать только цельнометаллические самолеты, побудила конструкторов "Armstrong Whitworth" переделать самолет. После постройки нескольких машин смешанной деревянно-металлической конструкции, в мае 1923 года в воздух поднимается цельнометаллический Siskin Mk III. За опытной машиной последовала предсерийная партия из трех самолетов, первый из которых поднялся в воздух спустя 10 месяцев после прототипа.
Рекламное турне по Европе принесло заказ на 65 истребителей от Румынии - первый самолет из этой партии поднялся в воздух в октябре 1924 года, до конца года заказчик получил еще шесть машин, но дальнейшие поставки были аннулированы из-за катастрофы истребителя Siskin в Румынии.
Первые истребители Siskin Mk III поступили на вооружение 41-й британской авиаэскадрильи в мае 1924 года (авиабаза Нортхолт), а в следующем месяце новую технику получила 111-я эскадрилья - самолеты Siskin пришли на смену истребителям Sopwith Snipe. Всего было построено 465 истребителей Siskin Mk III, включая несколько двухместных самолетов. Эстония. Канада и авиашкола фирмы "Armstrong Whitworth" получили двухместные учебно-тренировочные варианты истребителя, тогда как британские ВВС получили несколько новых двухместных самолетов, а затем переоборудовали в УТС дополнительное количество машин.
Лучшим стал вариант Siskin Mk IIIA, в прототип которого переделали серийный Siskin Mk III (первый полет - октябрь 1925 года). Значительного увеличения летных характеристик удалось добиться за счет установки двигателя Armstrong Siddeley Jaguar IV. Для британских ВВС построено 387 самолетов Siskin Mk IIIA, включая 47 учебно-тренировочных машин с двойным управлением. Большинство, за исключением 135 самолетов, были изготовлены субподрядчиками - "Bristol" (84 машины), "Gloster" (74), "Vickers" (52) и "Blackburn" (42).
Новой модификацией в сентябре 1926 года первой перевооружили 111-ю эскадрилью, за которой последовали еще 10 эскадрилий. Процесс снятия самолетов с вооружения начался в 56-й эскадрилье, получившей самолеты Bristol Buldog в октябре 1932 года. По результатам испытаний двух самолетов Siskin Mk III канадские ВВС заказали партию из 12 Siskin Mk IIIA, поставленных в 1926-1931 годах (частично это были новые истребители, остальные - снятые с вооружения британских ВВС). Истребители Siskin в 1-й истребительной эскадрилье канадских ВВС были заменены в 1 939 году самолетами Hawker Hurricane, но оставались на хранении до 1947 года.

The Paris Aero Show 1924
SIR W. G. ARMSTRONG-WHITWORTH AIRCRAFT, LTD., PARKSIDE, COVENTRY
THIS firm - the aircraft branch of the world-famous engineering house bearing the same name - will form a worthy representative of British aeroplane design and construction at this year's Paris Aero Show. While only one machine will be exhibited by this firm, the example to be shown - an A.-W. "Siddeley-Siskin 5" - consists of one of the most recent efforts of the company.
The "Siskin 5" is a high-performance single-seater fighter tractor biplane, fitted with an Armstrong-Siddeley "Jaguar" radial air-cooled engine. In general design the "Siskin 5" is similar to the previous "Siskins," which have made names for themselves during the past few years, both in military work and in civil aviation - it was a "Siskin II" that won the 1923 King's Cup or Circuit of Great Britain Race. There are, however, many minor improvements and modifications to be found in the "Siskin 5," the result of practical experience under service conditions with the earlier models.
"Siskin 5" is constructed very largely of metal, and possesses several distinctive features. It is of comparatively short span (28 ft. 4 ins.), and the top plane is considerably larger, both as regards span and chord, than the lower one. The wing cellule is of the "one-and-a-half bay" type, there being one pair of sloping interplane struts near the wing tips on each side of the fuselage, and in addition a pair of "half-struts" extending from the top longerons of the fuselage up to the top plane, about one-third the distance between the centre of the top plane and the interplane strut attachments. Both top and bottom planes are in two sections, the lower sections being attached directly to the fuselage, while the inner ends of the top sections are attached to an inverted V cabane above the fuselage. Unbalanced ailerons axe mounted on the top plane only, and both the upper and lower planes are set at a fairly pronounced dihedral angle.
The fuselage, it will be noted, presents a good streamline form, while the pilot's cockpit is well situated as regards good all-round vision. The pilot's head comes only just a little distance below the trailing edge of the top plane, which is cut away slightly at this position. The pilot thus has unrestricted vision directly forward, with a minimum of "blind" area upwards, while the lower planes, being comparatively small, do not restrict the downward view to any great extent.
Large vertical tail surfaces, and an adjustable horizontal surface, are provided. The Siddeley "Jaguar" engine is supported in a special steel cone mounting on the nose of the fuselage. This mounting enables the engine to be removed from the machine with the greatest facility and quickness, and without interfering with the carburetor adjustments, etc.
Another noteworthy feature of the "Siskin" is the somewhat unusual Oleo undercarriage. This consists of a usual V-chassis attached to the fuselage beneath the wings, but the wheels are not attached directly to the Vs. They are, instead, located some distance forward of the V-struts, to which they are hinged by radius arms from the apex of each V. The axle of the wheels is attached to two Oleo struts extending from the front end of the fuselage.
The main characteristics of the "Siskin 5" are :-
Span (top) 28 ft. 4 ins. (8-625 m.).
Span (bottom) 22 ft. (6-705 m.).
Chord (top) 6 ft. (l-828m.).
Chord (bottom) 5 ft. (1-524 m.).
Overall length 21 ft. 4 ins. (6-500 m.).
Height 9 ft. 4 ins. (2-834 m.).
Area of main planes 256 sq. ft. (23-782 mq.).
Weight fully loaded 2,450 lbs. (1,111-320 kgs.).
Maximum speed (full load) 155 m.p.h. (248 km.p.h.).
Speed at 10,000 ft. (3,048 m.) 147 m.p.h. (235-2 km.p.h.).
Speed at 15,000 ft. (4,572 m.) 140 m.p.h. (224 km.p.h.)
Climb to 5,000 ft. (1,524 m.) 2 mins. 40 secs.
Climb to 10,000 ft. (3,048 m.) 6 mins. 10 secs.
Climb to 15,000 ft. (4,572 m.) 11 mins. 30 secs.
Climb to 20,000 ft. (6,096 m.) 20 mins. 10 secs.
Service ceiling 25,000 ft. (7,620 m.).

Hot or cold! The extraordinary success with which the Armstrong-Siddeley "Jaguar" air-cooled engine functioned at temperatures in the neighbourhood of 110°F. during Cobham's recent London - Cape Town flight is still fresh in everyone's mind. The accompanying illustration is therefore particularly interesting inasmuch as it shows that this remarkable engine is equally at home at the other extreme. It depicts an "A.-W. Siskin" on which Lieut. Luneberg, of the Swedish Flying Corps, made a successful test in the far north of Sweden, with a temperature below 60 of frost, and then made a flight of 800 miles to the south of Sweden.

A typical Siskin IIIa, J8954 was built under subcontract by Gloster Aircraft Co Ltd and served with No 41 Sqn from February 1928. The engine was a 450 h.p. Armstrong Siddeley Jaguar IV air-cooled radial. Although a rugged and dependable fighter, the Siskin lacked streamlining when compared to the Hornet/Fury, as is obvious here.

Siskin IIIA No 20 of the RCAF previously bore the civil registration G-CYZF and later became 302. It survived until after World War Two.
No 21 was previously G-CYZE and later 303. It survived until after World War Two.
The sole A. W. Siskin of the R.C.A.F. This was a Mark III. Mr. McNulty points out that the serial "10" on the rear fuselage illustrates the first occasion on which the numeral system of the R.C.A.F. was employed (from 1930 onwards). Previously the system had been two letters, from " AA" to "ZZ'. The unique Canadain Siskin Mk. III may have been ex-R.A.F. J7759. Note how the older Mk.III's extended tailskid raised the tail, thus giving better forward vision for taxi-ing.
Rare bird is this Siskin Mk. IIIA of the R.C.A.F. According to Mr. Stone, this aircraft was one of eight serving as trainers.
A Canadian Commemoration: To commemorate the tenth anniversary of the first transatlantic flight by Alcock and Brown, the Royal Canadian Air force marked the occasion at the annual Inspection of the Military Units at Camp Borden, Ont., by christening two of the latest Armstrong-Whitworth Siskin IIIA machines (Armstrong-Siddeley supercharged "Jaguars").
