Sasa Studying Magnetohydrodynamic Hypersonic Turbojet

They are working on the magnetohydrodynamic (MHD) energy bypass engine.

Basically, it uses MHD to extract energy from the air stream, which can keep the inlet temperatures for a turbojet manageable well beyond the normal limit of about Mach 3. They are claiming Mach 7.

Still, I'd like to see the first A in NASA doing more non-space related work, as this is clearly intended to be used with a booster.
