The RAE was certainly a key player. A team was sent to Germany to dismantle and bring back wind tunnels (Operation SURGEON, I think) and some German scientists were employed in the research establishments - certainly Dietrich Kuecheman worked in Aero Dept at Farnborough. His name is linked to the "carrots" designed to reduce drag on the Victor, and he apparently had a lot of involvement in deciding the planform of Concorde's wing.
