AVRO LANCASTER B1 FLY-BY AT THE LMA RAF COSFORD RC MODEL SHOW LINE - TBOBBORAP1 - 2022

DEANO & I SPENT THE WEEKEND FLYING & FILMING AT THIS GREAT RC MODEL AIRCRAFT SHOW HERE IN THE UK,
THE SHOW WAS RUN BY THE LMA (LARGE MODEL ASSOCIATION) AND IS IN ITS 27th YEAR (I THINK) AND THE AMOUNT OF LARGE SCALE HIGH QUALITY MODELS ON SHOW WAS STUNNING !

THE ICING ON THE CAKE FOR US BOTH WAS THE FLY-BY OF THE BATTLE OF BRITAIN MEMORIAL FLIGHT AVRO LANCASTER B1 WW2 HEAVY BOMBER WITH ITS FOUR MERLIN ENGINES ROARING AWAY OVER OUR HEADS - HAPPY MEMORIES FROM A GREAT WKD SPENT WITH GOOD FRIENDS !

Development -

In the 1930s, the Royal Air Force (RAF) was primarily interested in twin-engine bombers. These designs put limited demands on engine production and maintenance, both of which were already stretched with the introduction of so many new types into service. Power limitations were so serious that the British invested heavily in the development of huge engines in the 2,000 hp (1,500 kW) class in order to improve performance. During the late 1930s, none of these were ready for production. Both the United States and the Soviet Union were pursuing the development of bombers powered by arrangements of four smaller engines; the results of these projects proved to possess favourable characteristics such as excellent range and fair lifting capacity. Accordingly, in 1936, the RAF also decided to investigate the feasibility of the four-engined bomber.

The origins of the Lancaster stem from a twin-engined bomber that had been submitted to British Air Ministry Specification P.13/36 of 1936 for a twin-engined medium bomber for "world-wide use" which could carry a torpedo internally, and make shallow dive bombing attacks. Further requirements of the specification included the use of a mid-mounted cantilever monoplane wing, all-metal construction while use of the Rolls-Royce Vulture, which was in-development was encouraged. Twin-engine designs were submitted by Fairey, Boulton Paul, Handley Page and Shorts, using Rolls-Royce Vulture, Napier Sabre, Fairey P.24 or Bristol Hercules engines. Most of these engines were still under development and while four-engined bomber designs were considered for specification B.12/36 for a heavy bomber, the extra engines required the wing and overall aircraft structure to be stronger, increasing the structural weight.

Flight testing -

By mid-1940, Avro's chief design engineer, Roy Chadwick, was working on an improved Manchester powered by four of the more reliable but less powerful Rolls-Royce Merlin engines, specifically adopting the "Power-egg" installation developed for the Beaufighter II, and installed on a wing of increased span. Initially, the improved aircraft was designated as the Type 683 Manchester III but was subsequently renamed the Lancaster. The prototype, serial number BT308, was assembled by the Avro experimental flight department at Ringway Airport, Manchester, being modified from a production Manchester airframe, combined with the new wing to accommodate the additional engines. The first flight was made by test pilot H. A. "Sam" Brown on 9 January 1941 at RAF Ringway, Cheshire.

Flight testing of the new aircraft quickly proved it to be a substantial improvement over its predecessor. The first prototype was initially outfitted with the Manchester I's three-finned tail but this was revised on the second prototype, DG595, and subsequent production Lancasters used the larger elliptical twin-finned tail unit that were also adopted for the last Manchesters built. This not only increased stability but also improved the dorsal gun turret's field of fire. The second prototype was also fitted with more powerful Merlin XX engines.
