VTOL aircraft with a thrust-to-weight ratio smaller than 0.1, during vertical take-off/landing, obtains another vertical lift, besides traditional vertical lift generated by low-temp bypass duct directing, under the closing of the propelling nozzle (7) of low-temp duct (6) of a turbofan engine and the opening of the inlet (14) of the low-temp bypass duct (15), the low-temp air (18) from the low-temp duct (6) to flow, in form of low-temp planar jet (20), over the upper surface of the wing along the wingspan, by high-temp bypass duct (15) directing, under the closing of the propelling nozzle (5) of high-temp duct (4) of the turbofan engine and the opening of the inlet (8) of the high-temp bypass duct (9), the high-temp air (18) from the high-temp duct (4) to flow, in form of high-temp planar jet (13), above the low-temp planar jet (20) but not burn up the wing along the wingspan and enables the ailerons (1, 2) to control the balances more efficiently.
