The Saunders T.1 was the first aircraft built by the Saunders Company, a two-seat single-engined biplane with unusual monocoque fuselage construction. Only one was built. DevelopmentBefore World War I, the Cowes-based firm of S.E. Saunders Ltd was well known for its motor boats and in particular for Sam Saunder's patented method of jointing plywood structures for marine environments. In the absence of waterproof glues, Saunders sewed sheets together with copper wire, a method known by the trade name Consuta. Consuta-built hulls were produced by Saunders for several flying boats between 1912 and 1915, but most of the company's war time was spent building other companies' designs.[1] The T.1 (T for Henry Haberfield Thomas, its designer) was the first all-Saunders aircraft, appearing in 1917. It was a single-engined two-seat biplane with single bay wings. These were unswept, carried no stagger and had parallel chord apart from the tips; notable was the large interplane gap and the large (6 ft 4 in, 1.93 m) overhang of the upper wing, wire braced from upward extensions of the interplane struts. It had unbalanced ailerons on the upper wing only. The most unusual feature of the aircraft, though no surprise given Saunders' previous experience was the fuselage, a wooden frame with Consuta-fastened plywood panels, one of the earliest monocoque aircraft structures. This carried a conventional tail, with an unbraced tailplane and fin bearing unbalanced control surfaces. The pilot's cockpit was below the wing trailing edge with a pair of inboard cut-aways in the trailing edge of the lower wing to improved downward visibility. He controlled a synchronised forward firing Lewis gun and the observer, sitting behind in a separate cockpit, operated a Lewis gun mounted on a Scarff ring. Dual controls were fitted.[2] The T.1 was originally intended to be powered by a 200 hp (150 kW) Hispano-Suiza engine, but all of these were prioritised for S.E.5as and instead a water-cooled 150 hp (112 kW) Sunbeam Nubian was installed, with a radiator immediately behind the four-bladed propeller. Initially the single exhaust pipe went up from the nose at an angle of about 30° to the vertical, though this was replaced by a more conventional arrangement later.[2] The T.1 first flew in 1917 and seems to have flown quite well, the only reported problem being a tendency to engine overheating. Only one was built though and its intended role is not clear; development ended when its designer, H.H. Thomas, died in the 1918–19 influenza epidemic.[2] Specifications{{aerospecs|ref={{Harvnb|London|1988|pp=53–4}} |met or eng?=eng |crew=2 |capacity= |length m=7.21 |length ft=23 |length in=8 |span m=11.4 |span ft= (upper) 37 |span in=5 |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=3.435 |height ft=11 |height in=3.25 |wing area sqm=31.12 |wing area sqft=335 |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |wing profile= |empty weight kg=814 |empty weight lb=1,795 |gross weight kg=1,216 |gross weight lb=2,680 |lift kg= |lift lb= |eng1 number=1 |eng1 type=Sunbeam Nubian V-8 water-cooled |eng1 kw=112 |eng1 hp=150 |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=143 |max speed mph=89 |max speed mach= |cruise speed kmh=119 |cruise speed mph=74 |stall speed kmh= |stall speed mph= |range km= |range miles= |endurance h=3 |endurance min= |ceiling m=3,383 |ceiling ft=11,100 |g limits= |roll rate= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1=1× 0.303 in (7.7 mm) Lewis gun synchronised to fire forward through propeller |armament2=1× 0.303 in (7.7 mm) Lewis gun in observer's cockpit |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |lists= }} References{{commons category|Saunders-Roe}}
