A VTOL aircraft has a substantially delta-shaped lifting body fuselage with airfoils disposed along all three sides. In vertical flight mode the airfoils act as exhaust diverters. A flow of exhaust gas flows from a centrally located vertical flight gas diffuser over the top surface of the lifting body and then is directed downward by the airfoils to provide vertical lift. In vertical flight mode, the entirety of the exhaust from the engine is diverted to the vertical flight gas diffuser by means of a transition duct that diverts the flow of gas through a 90° upward bend into the vertical flight gas diffuser. In horizontal flight mode the transition duct is fully retracted to permits the entirety of the engine thrust to be directed rearward to propel the aircraft in a horizontal flight mode.
