An aircraft with this VTOL technology (the Invention) (6,7,8,9,10,18,19,20) can achieve VTOL even its thrust-to-weight ratio is smaller than 1. It is impossible for an aircraft with a thrust-to-weight ratio smaller than 1 to take off and land vertically with traditional technologies. The present invention, however, can achieve VTOL on these aircraft (6,7,8,9,10,18,19,20) by generating another lift force for VTOL by horizontally setting a Thin Wing (2) at the middle of the perpendicular line of the horizontal section inside the Air Intake Duct (5,6) in addition to the lift force obtained by traditional ways. This invention can be used to retrofit an existing aircraft to achieve VTOL or manufacture a VTOL aircraft with a thrust-to-weight ratio smaller than 1.
