The jet engines are versions of the EJ200 that were used in the original development of the Eurofighter. If I understand correctly, they're still owned by the Ministry of Defense, but they're no longer suitable for combat use. They were loaned on condition that Bloodhound runs a initiative to foster interest in science and technology in schools, and the original Bloodhound programme was very effective in that sense. I don't know what the current deal is since bankrupcy and the buyout last year, but I'm pretty sure Ian Wakehurst wouldn't have invested if the MoD hadn't agreed to the continued use of the engines. One of the complications of using the EJ200 is that the engine's own control systems assume the engine is in a Eurofighter. So the car control systems need to pretend to be a Eurofighter, as they can't modify the engine's control systems.
