Short Kent

The Short S.17 Kent was a British four-engined 15-seat biplane luxury flying boat airliner, designed and built by Shorts to meet a requirement from Imperial Airways for an aircraft with greater range than the Short Calcutta. The new aircraft was to have sufficient range to fly the stage from Mirabella, Crete, to Alexandria in Egypt without the need for refuelling stops in Italian colonial territory due to a political row which had led the Italian Government to ban British aircraft from its ports.

Three aircraft were built, each receiving its own name: Scipio, Sylvanus and Satyrus; they were referred to collectively within Imperial Airlines as the Scipio Class flying boats. Each had an aircrew of three (two pilots and a radio operator/navigator) and a steward to prepare meals and light refreshments for the passengers.

Design and development

The Short Kent flying boat was essentially an enlarged, four-engined version of the Calcutta, with the same passenger carrying capacity but with an increased payload for mail and fuel. It was powered by four Bristol Jupiter XFBM radial engines mounted on vertical struts between the upper and lower planes.

The wings were constructed using corrugated duralumin box spars and tubular rib assemblies, with a fabric covering and Frise ailerons on the upper and lower wings. Duralumin walkways were provided to allow ready access to the engines for maintenance purposes. The tail unit consisted of braced monoplane horizontal and vertical stabilizers; the tailplane was fitted with Flettner-type servo tabs for trimming on the Short Scylla which had the same wings and tail as the Kent.

The anodised duralumin fuselage was mounted below the lower wing, with the planing bottom of the hull made of stainless steel (as on the Singapore II) with a transverse main step. The use of stainless steel reduced the frequency of land inspections of the hull. The bimetallic corrosion problems experienced on the Singapore II hull had been solved; Short Brothers became the first company to master the technique of building seaplane floats and flying boat hulls in this combination of metals.

A quick-release hook (controlled by the pilots) was provided, which enabled the captain to start, warm up and (when required) run all four engines up to full power for takeoff while the aircraft was still attached to the mooring buoy.

Maximum comfort was required for passengers and crew: the Kent's passenger cabin was 8 ft 6 in (2.59 m) wide and 14 ft (4.27 m) long. The seating was arranged in four rows of facing pairs, with a centre aisle, Pullman-style. The steward's pantry, situated on the port side aft of the passenger cabin, was equipped with twin-burner oil stoves on which stewards (and the valets of valued passengers) could cook meals in flight. The toilet and washroom were opposite the pantry; the mail and freight compartment was further aft.

Special attention was paid to sound levels in the passenger cabin and crew's stations; accordingly the engines were fitted with exhaust collector rings and long tailpipes, to reduce exhaust noise inside the hull.

The cockpit, for two pilots, was fully enclosed (unlike that of the Calcutta's) with a separate Radio Officer's station directly aft of the cockpit.

Service history

In October 1930, Short Brothers started building the first of the three S.17 Kent flying boats (G-ABFA, named Scipio). It was launched and flown on 24 February 1931 by Shorts' Chief Test Pilot J. Lankester Parker and was in service in the Mediterranean in May of that year. The second (G-ABFB, named Sylvanus) was launched on 31 March 1931; the third Kent (G-ABFC, Satyrus) was launched on 30 April 1931 and flown for the first time on 2 May 1931.

Imperial Airways used the Kent aircraft on the Mediterranean stages of its routes to India and beyond, also using them to survey planned routes to South Africa and Australia.

On 22 August 1936 "Scipio", on its way back from India, flipped over and sank in "Mirabella Harbour" (between the mainland of Crete and the island of Spinalonga) after landing heavily, killing two passengers. Sylvanus was destroyed by fire at Brindisi on 9 November 1935. Only Satyrus survived to be taken out of service and scrapped in June 1938.

In 1933 Imperial Airways placed an order for two landplanes based on the Kent; known initially as the S.17/L and later as the L.17, these became the Short Scylla, of which two were built and given the names "Scylla" and "Syrinx".

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
