Avro Ashton
Avro Tudor 8
Flight trials of the Tudor 8 with paired Rolls-Royce Nene in single nacelles showed the need for tricycle undercarriage to keep the jet s clear from the ground when taxing.
The Tudor 9 was to have a tricycle u/c, however this type was not proceded with and the MoS placed an order with Avro for six somewhat similar research aircraft known as the Avro 706 Ashtons, they untilised the Tudor 2 airframe with thicker skins and shortened to Tudor 1 length.
