The four turbojet engines are embedded directly into the wings.
Jet engines: The turbojet engine, invented in Britain in the mid-1930s by Royal Air Force officer Frank Whittle, was given to the U.S company General Electric GE in 1942 to develop for use in World War II.
The engineering of the jet tech graft made it fairly straight forward for her and her crew to swap it in, replacing the GE turbojet that had to that point powered her Spirit, and many Spirits before.
Dual-propulsion (turbojet and rocket) or hybrid-propulsion systems like Skylon have been developed by British designers since the 1950s.
The main idea now is to develop an engine which is able to take the aircraft from the tarmac to mach 6+ using basically one engine which combines a turbojet, ramjet, and last but not least a scramjet.
Considering how far the work on scramjets has gotten the main sticking point is a turbojet with the capacity to accelerate the craft to high mach 3 speed at which juncture the ramjet would take over and the turbojet would be hidden in an enclosure.
My personal favorite is a reusable supersonic first stage based on turbojet engines, probably horizontal takeoff.
It is an open two-seater car with undulating side vents, a turbojet-like rear and an aggressive retractable spoiler.
The turbojet and the turboprop, engines developed during World War II, were enabling aircraft designers to come up with machines of phenomenal speed.
And it was not a British company, but a German one, that first flew an aircraft powered by a turbojet, the Heinkel He-178, a few days before the outbreak of World War II.
