The Bristol Thor, latterly Bristol Siddeley BS.1009 Thor, was a 16" diameter ramjet engine developed by Bristol Aero Engines (later Bristol Siddeley 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,[1] including the construction of a high altitude test plant (HATP), with a supersonic test cell, at their Patchway site.
The Bloodhound Mk.1 could attain a speed of Mach 2.2, while the Mk.2 was capable of just over Mach 2.7.[2]
