as shown in fig. 1 to 4, the cross-medium intelligent aircraft comprises a fuselage, wings, tail wings (horizontal tail and vertical tail), a flight control system, a power system and a detection system. The aircraft has the weight of 150kg, the length of the aircraft body, the wingspan and the height of the aircraft body of 3m/5.6m/1m, the thrust of 500N-1000N, 15kg-20kg of a small turbine engine, the maximum flat flight of 28m/s, the cruising speed of 15m/s, the endurance time of 45min in the air and 25min in water.

The wings adopt flapping wings, but the flapping wings are only used in water, and are locked during flying in the air, and lift force is generated by utilizing the pressure difference between the upper surface and the lower surface of the wings to fly.

The flight control system is internally provided with a controller, a gyroscope, a barometer, a speedometer and other related instruments, so that the aircraft can receive remote control instruction signals sent by a remote controller conveniently.

The power system adopts a double-power system and consists of a built-in storage battery and a propeller. When flying in the air, the lift force is generated by the pressure difference between the upper part and the lower part of the wing, and the two small turbofan engines provide enough thrust for flying. In water the engine is off and the battery, propeller and wing provide power.
