 The aircraft featured a double-walled fuselage, with the pilot controlling the aircraft from within the inner shell.The circular gap between this and the outer, cylindrical shell provided the inlet for the ramjet.It could not take off unassisted (ramjets cannot produce thrust at zero airspeed and thus cannot move an aircraft from a standstill) and was therefore intended to be carried aloft by a parasite aircraft mother ship, such as the four-engined AAS 01A & -B German-origin designs or the French-designed Sud-Est Languedoc four-engined airliners, and released at altitude.
