C.Barnes Short Aircraft since 1900 (Putnam)

Short Tractor Seaplanes (1912-14)

<...>
   Gordon Bell’s accident came at a time when important new designs were taking shape at Eastchurch, and his place was filled temporarily by Sydney Pickles, also a well-known freelance test pilot. Three new types of tractor seaplane were on the stocks, two for the Admiralty and one as Frank McClean’s private entry in the 1913 Circuit of Britain seaplane race. First to be completed was a large patrol seaplane, with a two-row 14-cylinder Gnome engine of 160 hp. Two of these had been ordered, plus seven with 100 hp Gnomes. They were developed from Horace Short’s original 42, modified in accordance with naval requirements resulting from the previous year’s service trials. Wing area was increased, stronger and larger rubber-sprung floats gave a reserve of buoyancy and the balanced rudders had triangular fixed fins in front. The roomy front cockpit provided ample stowage for wireless and other gear, and the pilot occupied the rear cockpit. The high aspect ratio wings were of the latest type with steel-tube struts, originally in two bays, with strut-braced upper extensions and uncompensated wide-span ailerons. The first seaplane with 160 hp Gnome (S.63, serial 81) was accepted after test flights by Samson (in Bell’s absence) on 17 July, 1913, and taken aboard H.M.S. Hermes, the Navy’s new depot ship, at Sheerness. Samson continued to fly 81 throughout the Naval manoeuvres, which lasted from 24 July till 1 August, with Fitzmaurice as his observer; Hermes was based on Great Yarmouth, and 81 was lowered overside whenever the rather heavy swell permitted, and flew successfully on 26, 27 and 31 July, reporting back the positions of ships by means of a Rouzet transmitter. On 1 August, 81 flew about 50 miles out, but on the return trip part of the cowling came adrift and cut several of the sparking-plug leads, stopping the engine; Hermes came to the rescue and found the drifting seaplane near its last reported position. It appears that 81 had been fitted with folding wings before taking part in this exercise, but they could only have been simply hinged, needing man-handling and locking from outside. It was decided soon afterwards that Hermes should be permanently equipped as a seaplane carrier, and for this purpose wing-folding became a necessity for all but the smallest scouts carried aboard her. The second 160 hp seaplane (S.64, serial 82) was completed in March 1914, and was followed by two more (S.65-6, 89 and 90), after a mechanical folding gear, operated from the cockpit, had been devised and tested. The development of this gear, covered by patents Nos. 1,792, 15,727 and 28,610 of 1913, was worked out on the original S.41, which was extensively rebuilt and reappeared, bearing its old serial 10, in November 1913, being among the 22 aeroplanes inspected at Eastchurch by Winston Churchill on 29 November. It had its original two-wheeled landing gear with skids, and the original fuselage had been reconditioned, with reinforced engine bearers, but the wings and tail surfaces were completely new and resembled those of 81, with two bays and steel struts; the wings were folded back for inspection by the First Lord, and it was flown by Gordon Bell later in the day.
   Gordon Bell had made a good recovery and returned to duty at Eastchurch during September, just in time to take the place of his erstwhile deputy Sydney Pickles, who, by an unhappy coincidence, had been the victim of an accident similar to Bell’s. This time it was not due to reckless flying, for the rudder-bar became jammed on the Champel biplane he was flying at Hendon on 20 September, causing him to spin in out of control; this time, too, his passenger (Mrs de Beauvoir Stocks) did not die, although her injuries prevented her from resuming her career as one of the few British women pilots of that time. Pickles himself returned to Eastchurch in April 1914, intending then to fly only his own Bleriot for pleasure, but five months later he volunteered for war service, and thereafter became a much sought-after seaplane test pilot, doing valuable work at Rochester and elsewhere. Rochester works were built between October 1913 and January 1914 on a site beside the Medway upstream from the bridge, this location being chosen partly because of the difficulty of testing seaplanes built at Eastchurch (they had to be taken along narrow roads to either Sheerness or Leysdown and there rigged before launching) but more because of the plentiful labour available in the Chatham district.
<...>
   The production batch of 100 hp Gnome seaplanes for the Navy reached completion at the end of 1913. Somewhat lighter and of less wing area than 81, they had three-bay non-folding wings, being intended for coastal patrol from shore stations. The first of them, S.69, was test-flown by Gordon Bell on 4 and 7 January, 1914, C. R. Fairey being observer on the first occasion and Maurice Wright on the second, which included the delivery flight to Grain, where it received the serial 74. Bell tested S.70, the second of the batch, on 16 January, taking up both Fairey and Wright together on one flight. Four more (S.71-74) were tested during the last week of January, and the last (S.75) was flown straight to Grain without landing on 1 February. It is not clear from the records whether these seven aircraft were test flown from Leysdown or Sheerness, but the latter seems probable because there was a crane there for launching after rigging the floats and wings on the pierhead; the ‘folders’ could, of course, be taken from Eastchurch to the pier by road without dismantling. These seven non-folding seaplanes (74-80) were shared between the air stations at Grain (with detachments at Clacton and Westgate) and Dundee, and the latter provided a flight of four for the Spithead Royal Naval Review on 18-22 July, 1914. On the same occasion were flown four of the latest 160 hp ‘folders’ (S.82-85, serials 119-122'), which had gone into service at Grain in May and June. Their double-row engines still gave trouble and old No. 10 had been fitted with a similar 140 hp Gnome in May for Samson to experiment with; overheating had been reduced by fitting large vertical exhaust stacks in the tops of the cowlings, discharging over the upper wings clear of the crews; in true nautical style, these funnels were decorated with one, two, three and four white rings to identify the four ‘folders’ which took part in the Review. These four and a fifth (S.86, 186) differed from the first four in having longer fuselages and larger fins to match their three-bay wings of increased span, but 89 and 90 had three-bay wings of the same span as the two-bay 81 and 82 and retained the original fuselage length and fin area. Four more non-folding seaplanes similar to 74 were assembled at Eastchurch in July 1914, apparently from spares, and became 180-183; of these, 181 had an 80 hp Gnome and the others 100 hp Gnome-Monosoupapes.
   On 15 June, 1914, the Calshot seaplane station, commanded by Longmore, had been inspected by the Board of Admiralty, including Prince Louis of Battenberg (First Sea Lord) and Winston Churchill (First Lord). The latter asked Longmore whether torpedo-dropping experiments already started by Flt Lieut Hyde-Thomson at Calshot could be speeded up; Longmore said they could if he were permitted to retain a certain 160 hp Short seaplane (which was 121), when he would undertake at an early date to carry and release a 14-in torpedo weighing 810 lb, which he had not so far been able to do with the Sopwith seaplane specially built for this task. This was agreed and (in Oswald Short’s own words):
   ‘Horace at once put in hand two new main float cross-bars, bent upward in the middle to allow the torpedo to be swung between the main floats clear of the water, and fitted a quick release catch [designed by Hyde-Thomson] to release the torpedo. With the late Gordon Bell, who was our test pilot, and Mr Bibby, one of our foremen, I went to Calshot Seaplane Base and erected the machine in a few hours. As I was talking to [Longmore] at his office door he received a telegram. He opened it and, having read it, remarked “We were nearer to war in 1911 than we are now”, but I did not know to what he was referring. ... By the time the machine was ready to take off it was already dusk. There was much activity too with the Sopwith torpedoplane which had been specially constructed for the purpose. It was at the water’s edge and mechanics were working on the engine. At Bell’s first attempt to take off, the Short seaplane did not gain enough speed even to straighten out the ailerons. I heard one of the rival mechanics say, “Safe as a house!” Gordon Bell returned to shore and reported one cylinder missing; this was soon put right and at the next attempt the seaplane took off, the torpedo was dropped and a magnesium flare attached to it enabled it to be found and picked up. It was now dark. This was the first torpedo taken up and launched from a seaplane in Great Britain, only a few days before war broke out.’
   In fact, the date was 27 July, 1914, and from this account it is clear that, even though Longmore flew 121 with a torpedo next day, it is to Gordon Bell that the credit of having made the first drop should go. With such a load the aircraft was flown solo and could only carry fuel for about 30 minutes; even so, it was loaded well beyond the stress limits permissible even in 1914 for regular service, so it was far from being an operational weapon; in spite of this, the other four 160 hp ‘folders’ were later equipped with torpedo gear and carried on Engadine, one of three converted cross-Channel steamers, but no torpedo was ever launched by them in action. In March 1915, 120-122 were shipped to Durban on the armed liner Laconia and thence taken on 23 April to Niororo Island; there they were intended to assist the Navy in flushing the German light cruiser Konigsberg from deep cover in the Rufiji delta, but their performance in that hot, humid climate was totally inadequate.
   The unreliability of the double-row Gnome led to alternatives being sought; in the case of the 100 hp seaplanes the remedy was found by replacing the original ten-cylinder two-row Gnomes by nine-cylinder single-row Gnome-Monosoupapes, and this may have been done at Grain before entry into service. An alternative to the 160 hp Gnome was more difficult to find, but the new range of water-cooled radial Canton-Unne engines produced in France by Salmson seemed promising. They were to be built under licence in England by the Dudbridge Ironworks of Stroud, Glos., and were already in use in the larger Farman, Sopwith and Wight seaplanes.
