VTOL aircraft with a thrust-to-weight ratio smaller than 0.08, during vertical take-off/landing, obtains most vertical lift, besides traditional small vertical lift by high-temp bypass slot outlet (6) directing, under its opening, the closing of the tail of the power-off jet engine (3) by the valve (7) in tail cone, the closing and the stretching of the propelling nozzle (5), high-temp air (8) to spout out along the inclined downward direction of the wingspan, by a centrifugal impeller (13) accelerating, under the connecting of the transmission shaft (11) with a jet engine (4), and the opening of the cabin doors (15, 17) of the inlet (18) of the low-temp duct (16) and the auxiliary engine's inlet (14), low-temp air (21) to flow through the low-temp duct (21) and flow over the upper surface of the wing but not burn up it along the wingspan direction, thereby generating most vertical lift and enabling ailerons (1, 2) to control balances of the aircraft.
