Bristol Thor
The Bristol Thor, latterly Bristol Siddeley BS.1009 Thor, was a 16-inch diameter ramjet engine developed by Bristol Aero Engines for the Bristol Bloodhound anti-aircraft missile.
Although Bristol Aero Engines acquired ramjet technology from the US company Marquardt, BAE put considerable effort into developing the Thor unit, including the construction of a high altitude test plant at their Patchway site, with a supersonic test cell.
The Bloodhound Mk.1 could attain a speed of Mach 2.2, while the Mk.2 was capable of just over Mach 2.7.
