Avro серий 618 Ten, 619 Five, 624 Six и 642 Eighteen
Avro серии 618 Ten появился в результате лицензионного соглашения 1928 года на выпуск в Британии очень удачного трехмоторного авиалайнера Fokker F.VIIB-3m. Соглашение "Avro" с "Fokker" позволило британской компании продавать самолет в странах Британского
Содружества, кроме Канады. Название Ten ("Десять") было принято, чтобы отразить, что самолет вмещает двух членов экипажа и восемь пассажиров.
После небольших изменений конструкции фюзеляжа Ten показали на авиационной выставке 1929 года в Олимпии, позднее он стал первой из пяти машин, проданной авиакомпании "Australian National Airways". Еще две купила фирма "Queensland Air Navigation Co. Ltd". Последний из уцелевших в Австралии самолетов в 1941 году эвакуировал людей с Новой Гвинеи. Несмотря на проявленный "героизм", самолет вскоре списали.
Пять машин серии 618 Ten продали британским авиакомпаниям: по два - фирмам "Imperial Airways" и "Airwork" и один - фирме "Midland & Scottish Air Ferries".
Последний серийный Ten в июле 1936 года попал в звено по испытанию беспроводной связи авиационного оборудования Королевского НИИ авиации, позже на нем установили однолонжеронное крыло.
Серия 642 Eighteen: вариант Fokker F. VIIB-3m (назывался Eighteen только в начале своего появления) сочетал в себе крыло от серии 618 с новым фюзеляжем

BRITISH AIRCRAFT AT OLYMPIA
A. V. ROE & CO., LTD.
OWING to the fact that the material dealing with the exhibits of A. V. Roe & Co. reached us very late, it has not been possible to include the article describing the Avro show machines in its proper place, alphabetically, and we have, perforce, had to place it here, at the end of our advance show report. While regretting the fact, we had no choice in the matter, as it was necessary to go to press with this week's issue of FLIGHT a good deal earlier than usual, and the makeup of the Olympia Show Report could not be deferred until the last minute.
At least four complete aircraft are expected to be shown on the Avro stand; An Avro 10, an Avro 5, an "Antelope," and a metal "Avian" with "Genet Major" engine. This engine is an entirely new type, produced by Armstrong Siddeley Motors, Ltd., and will make its public appearance for the first time at Olympia,
It is now several months ago that it was first announced that the British rights to construct the Fokker F.VII 3-m. had been acquired by A. V. Roe & Co., Ltd., and the machine to be known as the Avro 10 is, in fact, the first Manchester-built Fokker. It is a cantilever high-wing monoplane, powered by three Armstrong Siddeley "Lynx" engines, and has accommodation for eight passengers in the saloon and pilot and engineer or navigator in the cockpit.
The passengers' saloon is tastefully decorated and comfortably equipped, and the large windows, with the absence of a lower wing, give an excellent view outwards and downwards. A small step is permanently built on to the fuselage below the door, and no extra steps are required, owing to the low height of the fuselage above the ground.
Side-by-side seating accommodation is provided for pilot and engineer in the cockpit, and dual controls are fitted, with the usual foot bar for the rudder and wheel control for the ailerons. Three baggage compartments are available, with a total capacity of 114 cub. ft. Light luggage can be put in the racks under the roof of the saloon.
The three Armstrong Siddeley "Lynx" engines are mounted one in the nose of the fuselage and two outboard under the wing, from which they are supported on three bolts from, the main wing spars.
Constructionally, the Avro 10 follows closely the original Fokker practice. The fuselage is a structure of welded steel tube construction, with bracing either in the form of diagonal struts welded to the longerons, or in the form of the well-known Fokker wire bracing looped through steel tube quadrants welded into the struts.
The monoplane wing is of all-wood construction, with three-ply planking, and there is no wire bracing, either inside or outside, the wing being a pure cantilever.
A wide-track undercarriage is fitted, consisting on each side of a radius rod, a bent axle, and the telescopic leg, which is taken to the outboard engine bearer. Wheel brakes are fitted.
The main dimensions of the Avro 10 are: Length, overall, 47 ft. 6 in.; height, overall, 12 ft. 9 in.; wing span, 71 ft. 3 in.; maximum wing chord, 12 ft. 6 in.; wing area, including ailerons, 772 sq. ft.; total area of ailerons, 44-6 sq. ft.; area of tail plane and elevator, 72-3 sq. ft.; area of fin and rudder, 25-5 sq. ft.
The tare weight of the Avro 10 is 6,276 lbs. This figure includes the saloon equipment, which weighs 256 lbs., so that if the machine is to be used for other than passenger carrying, the tare weight is correspondingly reduced. The non-paying load may be made up as follows: Crew of 2, 360 lbs. fuel and oil for 4 hrs., 1,280 lbs.; wireless and lighting equipment, 205 lbs. Total, 1,845 lbs. The pay load in this case becomes 1,800 lbs., giving a total loaded weight of 9,921 lbs. For longer range, extra petrol can be carried without reducing the pay load, and the machine will, at a gross weight of 10,600 lbs., fly level without losing height with one engine shut off.
Performance figures for the Avro 10 are :- Full speed 115 m.p.h.; cruising speed, 100 m.p.h.; range at cruising speed, 400 miles; rate of climb at sea level, 675 ft./min.; time to 1,000 ft., 1-6 mins.; time to 5,000 ft., 9-5 mins.; time to 10,000 ft., 25 mins. Service ceiling, 14,000 ft. Absolute ceiling, 16,000 ft. Take-off run, 275 yards. Landing run without wheel brakes, 330 yards. Landing run with wheel brakes, 230 yards.
Avro серии 618 получил название Ten, поскольку был рассчитан на восемь пассажиров и двух членов экипажа. "Imperial Airways" получила первый самолет в 1930 году, эти машины использовались в основном для чартерных рейсов на европейских маршрутах.

ON TASMANIAN SERVICE: The Avro "Ten" operated by Hart Aircraft Co., Ltd., on their Melbourne - Launceston service flying over Melbourne. The Hart Aircraft Company, whose offices and hangars are located at Essendon Aerodrome, Melbourne, operate as well as the Melbourne - Launceston service, a general aircraft engineering service, a taxi service throughout the Commonwealth of Australia and a school of aviation. Their flying equipment consists of the Avro "Ten" (three-engined monoplane), a Desoutter ("Gipsy Mark III"engine), a "Hawk Moth" with a geared "Lynx" engine, and two "Gipsy Moths."

AVRO WELDED STEEL TUBE CONSTRUCTION: Circular engine mountings of the type shown in 1 are used both for fuselage and wing engines, but the actual supports of the rings differ slightly. The joint to the top longeron is shown in 2, with end fitting before welding shown at A and B. The fitting at the lower longerons is illustrated in 3, with details in 3C. The type of cowling support and attachment is shown in 4. In 5 is shown engine bracket before it is welded on to the engine ring, and 6 shows a bracket, a portion of the ring, and the attachment of a cowling tube.
AVRO WELDED CONSTRUCTION: A typical fuselage joint.
AVRO WELDED CONSTRUCTION: In the tail plane use is made of internal diagonal tubular struts of high-tensile steel. To avoid welding direct to this, mild-steel sleeves are used, as shown. The sketch also illustrates the welded tube tailplane ribs, the web being formed of continuous tubes welded to the flange booms.
