The Saunders-Roe (or abbreviated Saro ) A.27 London was a British flying boat made by the manufacturer Saunders-Roe , which was used for patrol flights.
development
The first version of the London with two engines Bristol Pegasus III of 875 hp each was built in 1935 and was designed as a long-range reconnaissance flying boat. Since the series production maturity of modern monoplane flying boats in Great Britain was delayed several times, a reinforced version of the aircraft came out in 1938. This machine, now called A.27 London II , remained in active service until November 1942, when it was replaced by the Short Sunderland and Consolidated Catalina flying boats . Until then, the London II was used in four squadrons of the RAF Coastal Command .
technical structure
The Saro London was a two-legged, braced one-and-a -half-decker with a braced double vertical tail . The wing and tail consisted of a steel frame with fabric covering, the hull boat (two-stage) and the support float (one-stage) were made of all-metal construction. The two engine nacelles were suspended under the middle section of the upper wing. Night and blind flight equipment was available.
