Saunders A-10

TerryLeave a comment

Having specialised in flying boats for a decade, in 1926 S E Saunders Limited began the design of a land-based single-seat all-metal fighter sesquiplane. This, the A.10 proposal, featured what was, for its time, the unusually heavy armament of four 7.7mm machine guns, power being provided by a 480hp Rolls-Royce F.XI 12-cylinder Vee-type engine. After revising the design in 1927 to comply with Specification F.20/27, Saunders built a prototype which flew on 27 January 1929.

Saunders A-10 Article

Possessing an all-metal structure with fabric covering and all four guns located in the fuselage, the A.10 suffered handling and performance shortcomings which led to numerous modifications, including fuselage lengthening. It was assessed at the A&AEE against other F.20/27 contenders and also for F.10/27 (which called for six-gun armament), but it aroused little enthusiasm and was struck off Air Ministry charge in November 1933 – by which time its manufacturer had become Saunders-Roe Limited.

Saulnier 1910 Monoplane

Raymond Saulnier did design work on the Blériot VIII and XI (the famous Channel machine). Some sources say he did most or all of the designing of the Type XI. He then started his own aeroplane construction firm at Courbevoie. His monoplane – which looks like a development of the Blériot XI – was an excellent flyer. The pilot was seated low in the completely open fuselage, a great difference with the Blériot. The machine was fitted with a two-cylinder Darracq engine and later with an Anzani 3-cylinder. The machine was mostly piloted by Emile Duval.

Saul Triad NX808M

The sole Triad 1000 (ATC 2-229) of 1930 was registered NX/NC808M c/n 1001.

It was reportedly scrapped in 1936 after its motors were traded for a new Porterfield. Assets of the corporation were liquidated in 1939 after the death of Irving Saul in 1933, but several accounts indicate that the aircraft was still operational long after that time.
