An aircraft includes: ailerons (1,2); a turbofan engine (3) comprising a high-temp duct (4) with an openable/ closable propelling nozzle (5), and a low-temp duct (6) with an openable/closable propelling nozzle (7); a high-temp bypass duct (9) comprising an openable/closable inlet (8) connected to the high-temp duct(4), an outer wall(10) and a rectangle outlet(12) with a height-to-width ratio smaller than 0.1; a low-temp bypass duct (15) comprising an openable/closable inlet (14) connected to the low-temp duct (7), an outer wall (16), an inner wall (17) and a rectangle outlet (19) with a height-to-width ratio smaller than 0.1. During vertical take-off/lading, closing the propelling nozzles (5, 7) of turbofan engine (3), and opening the inlets (8,14) of high-temp and low-temp bypass ducts(9,15), low-temp planar air jet (20) is cause to flow over upper surface of the aircraft, thereby generating lift and no air flow over lower one.
