S-43 Baby Clipper/JRS/Y1OA-8

Амфибия, двухмоторный цельнометаллический моноплан-парасоль. Создан в отделении "Сикорски эйркрафт" корпорации "Юнайтед эйркрафт" под руководством И.И. Сикорского. Военный вариант пассажирской амфибии S-43 "Бэби клиппер", проходившей испытания в 1935 г. Серийное производство S-43 начали в 1936 г. В следующем году стали строить варианты этой амфибии, принятые на вооружение армейской и морской авиации США. Всего вооруженные силы получили 23 машины этого типа.
Строились следующие военные модификации:
   - JRS-1 с моторами R-1690-52 для авиации флота, военно-транспортный самолет на 19 мест, в войну устанавливались бомбодержатели для глубинных бомб (весом до 225 кг);
   - Y1OA-8 с моторами R-1690-23 для армии, грузовой самолет без сидений в салоне;
   - OA-11, реквизированный армией пассажирский S-43 с моторами R-1690-S2C.
Стрелкового вооружения ни один самолет не имел.
В предвоенные годы машины семейства S-43 эксплуатировались американскими армией, флотом и морской пехотой. В 1942 г. JRS-1 привлекались к противолодочному патрулированию у западного побережья США и Гавайских о-вов, но в основном все эти машины летали как транспортные.
Последний самолет (OA-11) был приобретен армией в марте 1942 г. JRS-1 для флота прекратили строить в 1939 г.
Морская авиация США сняла JRS-1 с вооружения в конце 1942 г., ВВС армии - в конце 1945 г.
Чилийские ВВС эксплуатировали два S-43 гражданского варианта до конца 1938 г.

Sikorsky S-43

S-43 проектировался на базе S-42 и имел меньшие размеры. В качестве силовой установки использовались два звездообразных Pratt & Whitney R-1690 Hornet мощностью по 750 л. с., а оперение было не двухкилевым, а с одним килем. В стандартном варианте самолет брал 15-18 пассажиров.
   Первый полет S-43 выполнил 1 июня 1935 года, всего же компания Сикорского построила 50 S-43 и еще три были построены без шасси. Вариант S-43W оснащался двигателями Wright Cyclone и имел однокилевое хвостовое оперение, а варианты S-43B и S-43WB имели двигатели Pratt & Whitney или Wright и двухкилевое хвостовое оперение.
   "Pan American" приобрела 14 самолетов и была крупнейшим эксплуатантом машин данного семейства, применяя их на маршрутах в Латинской Америке. Среди других заказчиков - "Air France", гавайская "Inter-Island Airways", голландская "KNILM" и авиакомпании Чили, Китая, Норвегии и СССР. ВМС США также приобрели данные самолеты. В 1937-1939 годах ВМС закупили семь, а затем еще 10 S-43, включая два для авиации КМП США. Самолеты получили обозначение JRS-1, имели экипаж из 1-2 человек и использовались в качестве вспомогательных транспортных - могли брать на борт до 18 пассажиров или груз. Самолеты, полученные авиацией КМП США, входили в состав 1 -й и 2-й разведывательных эскадрилий авиации морской пехоты. Восемь машин, поступивших в авиацию ВМС США, входили в состав 1-й разведывательной эскадрильи, дислоцированной в Сан-Диего. После 1941 года в эксплуатации оставался лишь один JRS-1. Армия США располагала четырьмя вспомогательными транспортными самолетами данного семейства - они обозначались OA-8/OA-11.

AMERICA'S LATEST AMPHIBIAN
The Sikorsky S.43: Exceptional Load Capacity and High Cruising Speed

   DURING a recent visit to America the writer was invited up to Bridgeport, where the Sikorsky amphibians are made. After seeing aircraft factories in most of the European countries it was particularly interesting to have an opportunity of inspecting the methods of the U.S.A.
   Sikorsky's have been much in the limelight recently by virtue of the performance of their S.42, the large flying-boat which has been built for Pan American Airways to use over their ocean routes. Three of these have been delivered, and seven more were to be seen under construction; incidentally, these later models will have a gross weight of 41,000 lb. instead of 39,000 lb. as hitherto, so that the ratio of gross to tare is 1.95, which means that this boat carries 95 per cent, of its own weight. With a load capacity of this size flying begins to look as profitable as any other means of transport.
   Amphibians (or perhaps my American friends would prefer amphibions) have, however, always been Igor Sikorsky's chief interest, and during my visit I saw the latest of these, the S.43, nearing completion. This aircraft has now flown and it seems very probable that the estimated figures are likely to be fully substantiated, in which case operators all over the world will undoubtedly be very interested indeed. With a ratio of gross weight to tare weight of nearly 1.7 the percentage load carried is unusually high for an amphibian. The figure, indeed, is reasonably good for a land machine, but in this case the operator will have the great advantage that his aeroplane can be used from both land and water bases.
   The S.43 is roomy inside, with a standard cabin arrangement of from fifteen to twenty-five passengers and a crew of three. The power plant is two Pratt and Whitney S1EG geared "Hornet" engines of 750 h.p., which drive Hamilton Standard constant-speed airscrews.
   Structurally there is very little radical departure from accepted Sikorsky practice. The wing, which tapers heavily in plan and profile, has a span of 86 ft. and a total area of 780 sq. ft., giving a loading of 24.34 lb./sq. ft. Built of anodically treated duralumin, the wing is virtually of monospar construction in that the two spars are joined top and bottom with a flush-riveted duralumin skin to form a box, which for stress purposes is treated as a unit. Behind this spar the duralumin ribs are covered with doped fabric. The whole of the trailing edge of the wing between the ailerons forms a flap which is used for both take-off and landing, while the ailerons themselves are dropped 10 deg., without affecting the total movement, thus adding to the effective flap area. The flap is hydraulically operated, a small electric motor working the hydraulic pistons, and is returned to the neutral position automatically. The rudder is balanced by an automatic trailing-edge servo tab.
   Widespread use is made of extruded light alloy sections for such parts as wing spar booms, internal struts, and stringers.
   The hull is of duralumin and is anodically treated everywhere. American practice employs anodic treatment not so much for prevention of corrosion itself as to form a somewhat absorbent surface to which protective paint coverings will adhere. Much use is made of open extruded sections so that inspection is simple, and any signs of corrosion can immediately be detected.
   Of semi-monocoque construction, the hull is divided into five main watertight compartments, with doors in each bulkhead. Any three of the five compartments will keep the S.43 afloat, in addition, the wing is capable of being sealed to form additional buoyancy chambers in the event of a forced landing at sea with a damaged hull.
   The retractable undercarriage is very neat. It is pulled up with a form of parallelogram motion into a watertight compartment in the centre portion of the hull, and the wheels drop in recesses which leave one half of the thickness outside; but, due to the shape of the tyre, the drag of this portion is not very large.
   Among details, it is interesting to note that the large anchor is non-magnetic.
   Both sides of the undercarriage are interchangeable, and may readily be removed if it is wished to operate only as a flying-boat.
   Sealed ball bearings are used in most places for the controls.
   Fuel is carried in riveted duralumin tanks behind each engine, and each tank has a large dump valve. Tanks and engine mountings are interchangeable. Lux CO2 pressure fire extinguishers are fitted in each engine nacelle.
   As it is a high-wing monoplane, the S.43 will appeal to passengers much more than do low-wing types, as they will be able to see the country over which they are passing.
   Having a payload which should make air transport economical even with an amphibian, it may well start a new regime whereby operators running to large cities will use an amphibian for their last stage, making it possible to land in the heart of the city on the river (which always seems to be there) instead of fourteen to twenty miles outside, as is now so often necessary.
   The more general use of the amphibian may also be a means of bringing the insurance rates down, due to the increased safety factor of being able to alight on either land or water.

The prototype of the attractive S-43, NC15061, during an early test flight. Three main variants were produced; the single-fin Pratt & Whitney Hornet-engined S-43A and a similarly-powered twin-finned version, the S-43B, which was usually delivered as a flying-boat and operated from water only. The final variant, the S-43W, was powered by Wright Cyclones.
The S-43 was an 86 ft span eighteen-seater, so it was a lot bigger than previous Sikorsky twins. It undoubtedly benefitted from the design experience gained with the S42 and the first machine, NC15061 c/n 4301X, after prototype testing, went straight to a customer, Inter Island Airways who also had the second aircraft.

Inter-Island Airways, the transport company linking the Sandwich group, use Sikorsky S.43 amphibians, one of which is seen flying over the coastline of Hawaii. The apparently bare and gloomy rock is, in fact, a mass of vegetation.
An Inter Island Airways S-43, believed to be NC15062, over dramatic Hawaiian coastal scenery.

HONOLULU BOUND: Such a prosaic excrescence as the wing-tip float of a Sikorsky S.43, used on the Hawaiian inter-island service, assumes a dramatic aspect against this Pacific background.

Регистрационный номерRegistry number: F-AREX [11], LN-DAG [11]
The Sikorsky S-43 LN-DAG is shown here as F-AREX. It was sold to Cie des Chargeurs Reunis with French CofA issue on 27.9.38. En route to France it had been checked at Schiphol by Veritas with 197 flying hours logged. Registered F-AREX on 19.10.38 it was delivered via Marseille to Abidjan. The S-43 was used in the Gold Coast region and flew the first seaplane services into Lagos, Nigeria. The photo shows it moored on the inland waterway at Lagos during unloading/loading operations. Aeromaritime (Cie des Chargeurs Reunis) operated between Pointe Noire and Dakar where the S-43s linked up with Air France services. F-AREX was last checked by Veritas in Abidjan on 16.12.43 with 1691 hours. It was cancelled from the register 11.3.46 as "dilapidated".

One of several S-43 amphibians operated by Compagnie des Chargeurs Reunis, which formed its own airline, Aeromaritime, in the early 1930s, to operate scheduled services along the West African coast, from Dakar in Senegal to Pointe Noire in French Equatorial Africa (now the Republic of Congo).

Регистрационный номерRegistry number: NC20697, PK-AFX
Late production twin-fin S-43B NC20697 c/n 4351 was Fleet No.8 of Inter-Island Airways but after two and a half years it was sold to KNILM and re-registered PK-AFX. Less than six months later it was destroyed in a Japanese attack. Note the nose flare for better spray control.

Регистрационный номерRegistry number: PK-AFU
C/n 4353 PK-AFU, a twin-fin S-43W (W for Wright 760 hp GR-1820-F52 Cyclone 9-cyl radial engines with fully feathering constant speed propellers) was the last S-43, delivered 3.1.41. Like PK-AFT it was listed as an S-43WB, ie flying boat version, although the photos show both as amphibians so possibly the land undercarriage was later removed. Clearly visible is is the ferry registration XPK-AFU in which it was delivered to the Netherlands East Indies.

Регистрационный номерRegistry number: NC16927
Pan American's S-43B NC-16927 c/n 4316 at full throttle with 15° of flap is nearing lift-off speed. This aircraft was one of a number modified to have twin fins and rudders and the bow lengthened by 13 in and flared to reduce spray action.
The Norwegian airline expected to be allocated an S-43 from the PAA order (one of which, twin-finned S-43B NC16927, is seen "on the step").

A rare DNL timetable for the summer of 1937, prominently featuring the airline’s most recent acquisition on the outer flap. The S-43 was little used, however, and, by the time this timetable was issued, considerable efforts were being made to find a new owner for it.
