The Sopwith Schneider of 1919 was a British racing seaplane. It was a single seat biplane intended to compete in the 1919 Schneider Trophy. After this race was abandoned due to fog, the Schneider was rebuilt into a landplane racer as the Sopwith Rainbow, being destroyed in a crash in 1923. Development and designIn 1919, it became possible to restart the Schneider Trophy races for seaplanes, which had not been held since 1914 owing to the First World War. As it was last won by the Sopwith Schneider development of the Sopwith Tabloid, the race was organised by the British Royal Aero Club, and was planned to be held at Bournemouth on 10 September that year. In order to compete in the 1919 race, the Sopwith Aviation Company designed a small floatplane, powered by the new Cosmos Jupiter radial engine.[1] It was of all-wooden construction, with single bay wings.[2] Operational historyThe Sopwith entry, registration G-EAKI, along with entries from Supermarine (the Sea Lion) and Fairey (the Fairey III) was one of three British entries to compete in the race (the Avro 539 was eliminated prior to race-day).[3] On the day of the race, the weather was poor, with thick fog.[4] The Sopwith, flown by Harry Hawker together with the Fairey entry, abandoned the race owing to the fog,[5] while the Supermarine aircraft hit debris following alighting to try to find where it was on the course, sinking when it tried to land again.[6] The only aircraft to complete the race, the Italian SIAI S.13 was disqualified as the pilot consistently missed one of the turning points,[5] the race being declared void. In 1920, the Schneider Cup racer was rebuilt as a landplane and re-engined with a 320 hp (239 kW) ABC Dragonfly as the Jupiter engine which powered it in 1919 was unavailable, and known as the Sopwith Rainbow. It was entered into the 1920 Aerial Derby, but was disqualified.[8][7] It was rebuilt again in 1922 by H.G. Hawker Engineering, (Sopwith Aviation having gone into receivership in 1920), being fitted with a Bristol Jupiter II. It finished second in the 1923 Aerial Derby on 6 August,[8][8] but was destroyed in a crash on 1 September 1923.[8] Specifications (Schneider){{aerospecs|ref=British Civil Aircraft 1919-1972:Volume III [9] |met or eng?=eng |crew=1 |capacity= |length m=6.55 |length ft=21 |length in=6 |span m=7.32 |span ft=24 |span in=0 |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m=3.05 |height ft=10 |height in=0[10] |wing area sqm=20.6 |wing area sqft=221.75[11] |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |wing profile= |empty weight kg= |empty weight lb= |gross weight kg=1,000 |gross weight lb=2,200 |lift kg= |lift lb= |eng1 number=1 |eng1 type= Cosmos Jupiter |eng1 kw=336 |eng1 hp=450 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh=274 |max speed mph=170 |max speed mach= |cruise speed kmh= |cruise speed mph= |stall speed kmh= |stall speed mph= |range km= |range miles= |endurance h= |endurance min= |ceiling m= |ceiling ft= |g limits= |roll rate= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |lists= }} Notes1. ^Flight 28 August 1919, p.1154. 2. ^Flight 4 September 1919, p.1183. 3. ^Flight 11 September 1919, p.1225. 4. ^Flight 18 September 1919, p.1247. 5. ^1 Flight 18 September 1919, p.1249. 6. ^Flight 18 September 1919, p.1253. 7. ^Flight 29 July 1920, p.841. 8. ^Flight 9 August 1923, p.467. 9. ^1 2 3 Jackson 1988, p.310. 10. ^Robertson 1970, pp. 236-237. 11. ^Flight 4 September 1919, p.1184.
