Avro 530

The Avro 530 was a British two-seater fighter biplane prototype that was designed in 1916 and completed in July 1917.
It was designed to compete against the Bristol F.2A.
It was made out of wood and was covered in fabric and powered by a 200hp Hispano-Suiza 8Bdeight-cylinder water-cooled engine.

When tested, it proved to be a good airplane with good performance rates, however it didn't significally improve the Bristol F.2A performance rates and therefore no production orders were issued.
Also should be considered that back in 1917 the Hispano-Suiza engine's priority was the RAF SE.5a. In order to cope with that, a second prototype was started to be built, powered by a Sunbeam Arab engine, but it's development was abandoned.
