Avro 547
The Avro 547 was a prototype triplane airliner developed in Britain after World War I. It utilised components from the highly successful Avro 504 but added an extra set of wings and a new deep fuselage housing a fully-enclosed cabin to seat four passengers. The aircraft was powered by a 160 hp (120 kW) Beardmore engine. The pilot sat in an open cockpit offset to port. The prototype flew well, having similar characteristics to an Avro 504,[1] the second example built was substantially modified, in order to compete in a British Air Ministry competition for a commercial aircraft, being fitted with a 240 hp (179 kW) Siddeley Puma engine. Designated 547A, this version turned out to be slow and unstable in the air and failed to win an award in the competion in August 1920.[1]. Damaged in a forced landing at the competion, the second prototype was scrapped in 1922.[2]
Despite this, Qantas bought the first prototype in November 1920 for GBP 2,798 with the intention of using it on a route between Charleville and Katherine. It first flew after re-assembly in Australia on 2 March, 1921, being damaged on landing and not being repaired for over a year. The 547 proved utterly unsuited to outback conditions and was quickly decommissioned, its fuselage ending its days as a chicken coop in Sydney.[3]
