Abstract
Description
Technical Field
[0001] This utility model is a butterfly-shaped fixed-wing remote-controlled aircraft, belonging to the field of aircraft technology. Background Technology
[0002] The flight principle of the butterfly fixed-wing aircraft is primarily based on aerodynamics. Its airfoil design creates a pressure difference between the upper and lower surfaces of the wing during flight, thus generating lift. Simultaneously, by adjusting the angle and speed of the wing, the aircraft's climb, dive, and turn maneuvers can be controlled. This flight principle ensures the butterfly fixed-wing aircraft possesses excellent stability and maneuverability in the air.
[0003] Chinese Patent Publication No. CN212818103U proposes a butterfly-shaped fixed-wing remote-controlled aircraft. Its elegant butterfly-like design, combined with meticulously painted patterns, creates a beautiful sense of artistry and harmonious vitality, greatly enhancing the enjoyment of flight and possessing significant and broad market prospects. However, the connection point at the rear of the butterfly-shaped fixed wing is fixed. When multiple tests of different flapping angles are needed, multiple aircraft with different fixed wing positions must be used for testing, significantly increasing costs and test preparation time. There is an urgent need for a butterfly-shaped fixed-wing remote-controlled aircraft to solve these problems. Utility Model Content

Detailed Implementation
[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Please see Figures 1-5This utility model provides a technical solution: a butterfly-shaped fixed-wing remote-controlled aircraft, including an aircraft central axis 1, butterfly wings 2, butterfly wing frames 3, servo motors 4, a central control connecting ring 5, a battery 6, a control board 7, and a fixed-wing tail-end connecting mechanism 8. Servo motors 4 are installed on both sides of the aircraft central axis 1, and butterfly wings 2 are respectively arranged on both sides of the aircraft central axis 1. A butterfly wing frame 3 is installed on the upper surface of the butterfly wings 2. The fixed-wing tail-end connecting mechanism 8 is installed on the circumferential surface of the aircraft central axis 1, and a central control connecting ring 5 is installed on the circumferential surface of the aircraft central axis 1. A control board 7 is located at the lower end of the central control connecting ring 5, and a battery 6 is located at the lower end of the central control connecting ring 5. The fixed-wing tail-end connecting mechanism 8 includes a connecting... The connecting strip 81 is mounted on the circumferential surface of the central axis 1 of the aircraft. The central axis locking bolt 82 is installed above the connecting strip 81. Adjustment brackets 84 are set on both sides of the connecting strip 81. Tail-end locking bolts 83 are installed on both sides of the connecting strip 81. Tail-end locking bolts 85 are installed at one end of the tail-end locking bolts 83. This design solves the problem that the connection point of the rear end of the butterfly fixed wing of the original aircraft is fixed in a fixed position. When it is necessary to test different flapping angles of the fixed wing multiple times, multiple aircraft need to be tested with different fixed wing fixed positions, which greatly increases the cost and test preparation time.
[0015] In the first embodiment of this utility model: the adjusting frame 84 is fixedly connected to the rear end of the butterfly wing frame 3. The adjusting frame 84 passes through the front and rear end faces of the connecting strip 81. The two adjusting frames 84 are parallel to each other. Tail-end locking grooves 812 are respectively opened on both sides of the connecting strip 81. The tail-end locking grooves 812 are located on the side of the adjusting frame 84. The tail-end locking bolt 83 passes through the tail-end locking groove 812 and the adjusting frame 84. The tail-end locking cap 85 is located below the connecting strip 81. Two central axis locking grooves 811 are opened in the middle of the connecting strip 81. Two central axis locking slots 811 are located on both sides of the central axis 1 of the aircraft. The central axis locking bolt 82 passes through the central axis locking slot 811 and the connecting strip 81. The central axis locking bolt 82 and the connecting strip 81 below the central axis locking slot 811 are connected by threads. The upper surface of the tail end locking bolt 83 is provided with a long strip-shaped protrusion. The tail end locking bolt 83 and the tail end locking cap 85 are connected by threads. By adding the long strip-shaped protrusion, the connecting strip 81 can be fixed on the adjustment frame 84 without the need for tools, making the fixing more convenient.
[0016] As a second embodiment of this utility model: When it is necessary to adjust the connection point between the tail end of the butterfly wing 2 and the central axis 1 of the aircraft, simply loosen the central axis locking bolt 82 with an Allen wrench, and then pinch the tail end locking bolt 83 and the tail end locking cap 85 and loosen them to separate the tail end locking bolt 83 and the tail end locking cap 85. At this time, the connecting strip 81 will reduce the pressure on the adjusting frame 84 and the central axis 1 of the aircraft, thereby reducing the friction. Then the connecting strip 81 can be slid to a suitable position. After tightening the tail end connecting bolt and the central axis locking bolt 82 again, the connection position between the central axis 1 of the aircraft and the butterfly wing frame 3 will change.
