The invention discloses a vertical take-off and landing method for a delta wing unmanned aerial vehicle and belongs to the field of unmanned aerial vehicles. According to the vertical take-off and landing method for the delta wing unmanned aerial vehicle, an unmanned aerial vehicle body is included, front rotor wings are arranged on the front sides of wings of the unmanned aerial vehicle body, and rear rotor wings are arranged on the rear sides of the wings; and the front rotor wings and the rear rotor wings are arranged in the vehicle body direction of the unmanned aerial vehicle body, side wings are arranged at the ends of the wings and are each in an A shape, and the unmanned aerial vehicle body can be vertically stored through the side wings. The front rotor wings can upwards rotate by 90 degrees, and the rear rotor wings can downwards rotate by 90 degrees; the take-off and landing method of the unmanned aerial vehicle adopting the structure comprises a transverse vertical take-off and landing mode and a vertical type vertical take-off and landing mode, and a parachute can be adopted for landing; and vertical take-off and landing of the delta wing unmanned aerial vehicle can be achieved, power is sufficient, safety is high, and limit of a site on taking off is overcome.
