PURPOSE: A vertical take-off and landing aircraft using variable rotary wings is provided to create thrust by employing a propeller engine and creating backward thrust with the rotary wings, thereby enabling efficient aviation. CONSTITUTION: A vertical take-off and landing aircraft comprises rotary wings, a tilting drive unit, and a propeller engine. The rotary wings create a floating force for the aircraft to take off. The tilting drive unit receives a signal from a cockpit and tilts a drive shaft to turn the rotary wing 90° to the front of a flying wing when the aircraft flies at middle-high speed. The propeller engine generates thrust and advances with the rotary wings which rotate to the front of the flying wing and propel frontward. The tilting drive unit comprises a receiver receiving a signal from the cockpit, a control device, and a servo motor which generates a rotating force for driving a pinion.
