There three small experimental delta aircraft that were manufactured to provide experience of delata aircraft handing, they were designated Avro 707A, B and C. They were all powered by the Rolls-Royce Derwent engine, which had no re-heat. (There is one at Cosford, details on there web site)
The prototupe Vulcan VX 770 was converted to Conway engines and was operated by Rolls-Royce from Hucknall during Conway developement untill it was lost at an airshow killing all the crew.
