1946 Aeroplane Spotter 19 Oct. 244/1 For the supersonic range of speeds, what is known as ‘after-burning’ was to be employed for generating even more thrust. The ‘after-burning’ consisted simply of fuel jets disposed annularly around the tail pipe or nozzle much in the same way as planned for the Athodyd or ram-jet.
