Embodiment 1
[0039] Please refer to Figure 4 , the present embodiment provides a wing 110, the leading edge of the wing 110 (windward direction during flight) is wavy.
[0040] In this embodiment, the inventors aim at the problem of dynamic instability that has plagued the world-class line-by-line aerobatic model aircraft for many years when it is flying with large maneuvering loops. After in-depth theoretical analysis and research on kinematics and aerodynamics, the mechanism, root cause and theoretical model of the problem were summarized, combined with the principles of bionics and flow control theory in aerodynamics; referring to the unique pectoral fin structure of humpback whales, The structure of the wing 110 based on the wavy leading edge is simulated, thereby increasing the critical stall angle of attack of the wing 110 and delaying the occurrence of the stall phenomenon.
[0041] In order to solve the problem of dynamic instability in the somersault flight of the wire-controlled ...
Embodiment 2
[0130] The present embodiment provides a method for manufacturing a wing 110, which includes the following steps:
[0131] Step 1: Make a sine wave leading edge template;
[0132] Step 2: Glue the rigid foam board to the front edge formwork;
[0133] Step 3: Grind the rigid foam board along the front edge template;
[0134] Step 4: A protective layer is coated on the surface of the rigid foam board.
[0135] In this embodiment, the material used to make the leading edge of the wing 110 is a rigid foam board. The specific method is as follows: 1. Use AutoCAD to draw the sinusoidal leading edge, and then use 2mm balsa wood chips to make a sinusoidal wave-shaped leading edge template; 2. Cut the rigid foam board into strips and glue it to the leading edge template; 3. Use The sandpaper is polished into waves along the leading edge template; 4. Finally, glass fiber and epoxy resin are coated on the surface of the wing 110 to make the surface smooth and durable.
Embodiment 3
[0137] Please refer to Figure 1 ~ Figure 3 , the present embodiment provides a wire-operated model aircraft, which includes the above-mentioned wings 110 and an aircraft body 100, the wings 110 are respectively installed on both sides of the aircraft body 100, and the aircraft body 100 is equipped with a control mechanism 120 for controlling the flight direction of the aircraft .
[0138] In this embodiment, the aircraft body 100 includes a fuselage 130, an empennage 140 installed on both sides of the fuselage 130 and the above-mentioned wing 110, a landing gear 150 installed at the bottom of the fuselage 130, and a landing gear installed on the head of the fuselage 130. The power system and the control mechanism 120 installed inside the fuselage 130; the skeleton of the fuselage 130, the wing 110 and the empennage 140 are all made of balsa material, and balsa wood is the lightest commercial material in the world because of its minimum melting weight, The material is uniform...
