Savoia-Marchetti S.66

Трехмоторная пассажирская летающая лодка S.66 создавалась на замену очень удачному самолету S.55P. Она сохранила двухкорпусную схему предшественника, но ее корпуса стали больше и получили элегантные обводы.
  Совершивший первый полет в 1931 году, прототип (получивший военный серийный номер MM229) был оснащен тремя 500-сильными (373 кВт) 12-цилиндровыми ПД Fiat A.22R водяного охлаждения, вращавшими толкающие винты. Пилоты размещались в закрытой кабине в передней кромке центроплана крыла. В каждом корпусе первоначально размещалось по семь пассажирских кресел, два спальных места и туалет. Корпуса и крыло были выполнены из дерева, а хвостовые балки и оперение - из стальных труб с полотняной обшивкой.
  Компания "Savoia-Marchetti" построила 23 серийных самолета, оснащенных более мощными двигателями Fiat A.24R, в каждом из корпусов которых размещались по 11 пассажиров.
  Коммерческая эксплуатация S.66 началась в конце 1933 года; самолеты использовались итальянскими авиакомпаниями "Aero Espresso Italiana", "Societa Idrovolanti Alta Italia" (SIAI), "Navigazione Aerea" и "Societa Aerea Mediterranea" (SAM). Их S.66 перешли по наследству новой итальянской национальной авиакомпании "Ala Littoria", эксплуатировавшей эти лодки до 1939 года. Несколько самолетов применялись итальянскими ВВС для поисково-спасательных операций в годы Второй мировой войны.

THE SAVOIA-MARCHETTI S.66

  NO doubt most of our readers are familiar with the large Italian Savoia S.55 twin-hull mono-seaplanes (already described in FLIGHT on various occasions) which, amongst other accomplishments, were used on the famous "Formation" flight across the South Atlantic led by Gen. Balbo. The S.55 is a Service bombing or torpedo machine with two engines in tandem, and recently the Savoia-Marchetti firm have developed this type into a commercial version, with certain modifications and improvements, known as the S.66.
  The S.66 is a tri-motor monoplane, with the double hull and tail outrigger arrangement of the S.55, of wood construction. The cantilever wings are of thick section, tapering towards the tips both in plan form and thickness; they are in three sections, a centre section which connects the two hulls and carries the three engine nacelles and the pilots' cockpit, and two outer sections set at a dihedral angle.
  The wings are built up of three spars - a main central one and two secondary ones - and spruce ribs, the whole wing being covered with three-ply and divided into 54 watertight compartments. It is thus capable of providing considerable buoyancy in the event of a forced descent on the water with damaged hulls. The wings are treated with special damp-resisting composition and varnishes.
  In the forward portion of the centre section is the pilots' cockpit, with two side-by-side seats, back-cushion Salvator parachutes, and dual control. The instrument board, with the engine controls below, is arranged in front of the seats. The pilots' cockpit communicates with the hulls, right and left, while a corridor, between the second and third centre-section wing spars, also connects the two hulls, enabling the mechanics to attend to the engines during flight - an opening being provided in the top surface of the centre section for this purpose.
  The two hulls are also of wood construction - poplar, spruce and ash - with a covering of birch and double cedar planking with inner layers of proofed fabric below the water line. The hulls are able to remain moored in the water for long periods. The V-bottom is provided with a single step. Each hull is divided into five divisions; forward is a small compartment with a companion ladder leading from the top deck and an entrance to the main cabin; next is the main passenger cabin seating seven passengers in sprung armchairs; then comes the passengers' luggage compartment (and entrance to the centre-section wing); behind this is a compartment with two sleeping berths (folding) and another companion way to the top deck; finally, a compartment for freight and mails. The wireless station is located in the main passenger cabin.
  Three 500-h.p. Fiat A.22R engines, with reduction gear and variable-pitch four-bladed metal propellers, are mounted in nacelles supported above the centre section by steel-strut cabanes, complete with water and oil-cooling radiators and motor-compressor for starting.
  The tail surfaces are carried on two V outriggers, each attached to one of the hulls. The horizontal stabiliser is provided with variable-incidence gear, and the one-piece elevator is balanced; there are three vertical rudders located in the slipstream of the propellers.
  In designing the S.66 special attention has been given to, apart from comfort and safety in the air, seaworthiness when on the water, and facility for repairs or replacements. As regards the latter, the various units of the machine may speedily be replaced; one of the hulls can be replaced in a day, or a wing unit, the complete tail, engine nacelles can all be replaced in a matter of a few hours each.
  The principal characteristics of the Savoia-Marchetti S.66 are :- Span, 33 m. (108 ft. 4 in.); O.A. length, 16,60 m. (54 ft. 6 in.); height, 4,90 m. (16 ft.); wing area, 125 sq. m. (1,345 sq. ft.); weight empty, 6,100 kg. (13,430 lb.); useful load, 3,000 kg. (6,600 lb.); total weight, 9,100 kg. (20,030 lb.); speed range, 95-235 k.p.h. (59-146 m.p.h.); range, 1,200 km. (745 miles); climb, 2,000 m. (6,560 ft.), 12 min; 3,000 m. (9,840 ft.), 22 min.; 4,000 m. (13,120 ft.), 37 min.; ceiling, three engines, 5,000 m. (16,400 ft.); two engines, 2,500 m. (8,200 ft.); take off in 30 sec.

The Italian Exhibits

  The Savoia-Marchetti S.66 is similar in general design to the S.55, i.e., is a cantilever twin-hull seaplane. It is, however, fitted with three instead of two engines (Fiat A-24 R of 700 h.p. each), driving pusher airscrews. With a disposable load of 3 040 kg. (6,680 lb.) the cruising speed is claimed to be 133 1/2 m.p.h. The machine is said to be capable not only of level flight but of climbing with any one of the engines stopped.
AN ITALIAN COMMERCIAL SEAPLANE: The Savoia-Marchetti S.66 twin-hull mono flying-boat. This machine, which was described in our issue for October 13 last, is a development of the S.55 type (which made the formation Atlantic flight in 1930-31) but is fitted with three 500-h.p. Fiat A.22R engines.
По сути, S.66 представлял собой увеличенный вариант S.55, оснащенный тремя, а не двумя двигателями. Самолет на снимке принадлежал авиакомпании «Ala Littoria».

A NEW REGIME: On October 28 Mussolini celebrated the anniversary of Rome's capitulation to Fascism by, among many other ceremonies, inaugurating the new combine of all the Italian Air Lines into one body called Ala Littoria, which means, in a broad sense, the Fascist Wing. Our photograph, taken at the seaplane port of Ostia, near Rome, shows men painting out the company's old name and painting in the new name in anticipation of the ceremony. The flying boat is a Savoia Marchetti S 66 which runs between Rome and Tripoli.
SIR JOHN SIMON IN ROME: The Foreign Secretary flew from Capri to Ostia in an Italian seaplane on January 3. On his arrival at Rome (shown here) he spent two hours with Signor Mussolini.
