Among them, bionic phoenix aircraft usually imitate the streamlined body structure and wing shape of the phoenix, not only for aesthetics, but also to optimize aerodynamic performance and reduce flight drag.
[0003] Existing biomimetic phoenix aircraft generally require a run-up or tossing to take off, making take-off and landing difficult. They also have certain requirements regarding weather and terrain, which affects the user experience. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing aircraft require a runway or jettison for takeoff, making autonomous takeoff and landing inconvenient, and proposes a biomimetic phoenix aircraft.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A biomimetic phoenix-inspired aircraft includes a fuselage with side wings fixedly mounted on both sides and a tail fin at the rear. It also includes: a fixed base fixedly mounted on the side wings, wherein a rotating frame is rotatably mounted at the end of the fixed base away from the side wings, and a first propulsion unit is mounted on the top of the rotating frame. The rotating frame can switch between takeoff / landing and cruise modes. When the rotating frame is in takeoff / landing mode, the top end face of the rotating frame is parallel to the horizontal plane; when the rotating frame is in cruise mode, the top end face of the rotating frame is perpendicular to the horizontal plane. A second propulsion unit is fixedly mounted within the fuselage, and the axis of the second propulsion unit is perpendicular to the horizontal plane.
[0007] To facilitate the rotation of the rotating frame and the switching of working states, preferably, a second motor is fixedly installed inside the fixed base, one side of the rotating frame is rotatably connected to the fixed base through a rotating shaft, and the other side of the rotating frame is fixedly connected to the output end of the second motor.
[0008] To facilitate the up-and-down swinging of the tail fin, preferably, a fixed shaft is rotatably provided in the fuselage near the tail section, one end of the tail fin extending into the fuselage is fixedly connected to the fixed shaft, and a worm gear is fixedly provided on the fixed shaft.

[0013] 1. This biomimetic phoenix aircraft has side wings fixed on both sides of the fuselage, and a fixed base fixed on the end of the side wing near the nose. A rotating frame is rotatably connected to the fixed base. During takeoff and landing, the ducted propulsion unit and the propeller work together to provide lift and achieve hovering.

This achieves autonomous takeoff and landing and can adapt to flight under various complex conditions.
[0014] 2. This biomimetic phoenix aircraft, by starting the third motor to drive the worm gear to rotate, can drive the fixed shaft and tail fin to swing up and down through the worm wheel. It can adjust its attitude in coordination with the flight control command to suppress pitch oscillations during the transition from hovering to level flight, thereby improving flight performance.
[0015] The parts not mentioned in this device are the same as or can be implemented using existing technologies. This utility model fixes a fixed base on the side wings on both sides of the fuselage, and rotates a rotating frame on the fixed base. During takeoff and landing, the ducted propulsion unit and the propeller work together to provide lift and achieve hovering.

It also includes: Fixed seats 502 are fixedly arranged on both groups of winglets 2. A rotating frame 5 is rotatably arranged at one end of the fixed seat 502 away from the winglet 2. The rotating frame 5 is in the shape of a "冂". A first propulsion unit is arranged at the top of the rotating frame 5. Here, we preferably design the first propulsion unit as a first motor 503 fixedly arranged at the top of the rotating frame 5, a propeller 501 is fixedly arranged at the output end of the first motor 503, and the axis of the first motor 503 is perpendicular to the top end face of the rotating frame 5. The rotating frame 5 can switch between a take-off and landing state and a cruising state. When the rotating frame 5 is in the take-off and landing state, the top end face of the rotating frame 5 is parallel to the horizontal plane. When the rotating frame 5 is in the cruising state, the top end face of the rotating frame 5 is perpendicular to the horizontal plane; A second propulsion unit is fixedly arranged in the fuselage 1. The second propulsion unit is close to the tail wing 3, and the axis of the second propulsion unit is perpendicular to the horizontal plane. Here, we preferably use a ducted propulsion unit 4 as the second propulsion unit. The ducted propulsion unit 4 includes a duct and a fan installed in the duct. The axis of the duct of the ducted propulsion unit 4 is perpendicular to the horizontal plane, and the duct penetrates through the fuselage 1, that is, both the bottom and the top are open. During take-off and landing, the fan is started to blow downward, the rotating frame 5 is in the take-off and landing state, and the ducted propulsion unit 4 and the propeller 501 can jointly provide lift during vertical take-off and landing to achieve hovering. When reaching the predetermined height, the rotating frame 5 drives the propeller 501 to achieve a 90-degree deflection to smoothly transition the thrust vector from vertical to horizontal to achieve the level flight of the aircraft.
[0026] During use, winglets 2 are fixedly arranged on both sides of the fuselage 1, a fixed seat 502 is fixedly arranged at one end of the winglet 2 close to the nose, the rotating frame 5 is rotatably connected to the fixed seat 502. During take-off and landing, the ducted propulsion unit 4 and the propeller 501 can jointly provide lift during vertical take-off and landing to achieve hovering. When reaching the predetermined height, the rotating frame 5 drives the propeller 501 to achieve a 90-degree deflection to smoothly transition the thrust vector from vertical to horizontal to achieve the level flight of the aircraft, realizing autonomous take-off and landing and adapting to flight under various complex conditions.
[0027] Refer to Figure 4 , A second motor is fixedly arranged in the fixed seat 502. One side of the rotating frame 5 is rotatably connected to the fixed seat 502 through a rotating shaft, and the other side of the rotating frame 5 is fixedly connected to the output end of the second motor. During use, by starting the second motor to drive the rotating frame 5 to rotate, the working state of the rotating frame 5 can be switched to achieve the switch between the take-off and landing state and the cruising state, improving the use effect.
