The invention discloses a heterogeneous vertical take-off and landing system which comprises a multi-rotor aircraft and a fixed-wing aircraft. The multi-rotor aircraft comprises a first motor, a firstpropeller and an undercarriage, a recovery net is fixed on the undercarriage, the fixed-wing aircraft comprises a second motor and a second propeller, and the fixed-wing aircraft further comprises anose hook device. The multi-rotor aircraft carries the fixed-wing aircraft to take off vertically, the fixed-wing aircraft is released in the air, the fixed-wing aircraft autonomously completes a flatflight task, the multi-rotor aircraft carries the recovery net to take off when the fixed-wing aircraft is recovered, a fixed-wing aircraft nose recovery device bounces off and hooks the recovery net, the multi-rotor aircraft carries the fixed-wing aircraft to fall, recovery is achieved, excellent vertical take-off and landing performance and high-speed flat flight performance of the fixed-wing aircraft are guaranteed in a flat flight phase, and recovery of the fixed-wing aircraft in the air is achieved, and the net collision process is completely autonomous. The heterogeneous vertical take-off and landing system can be applied to take-off and landing of aircrafts on extreme terrains.
