Problems solved by technology

[0002] As a new concept aircraft of bionic flight, the flapping-wing aircraft has many advantages and broad application prospects. At present, a large number of flapping-wing prototypes have been successfully developed, but the flapping-wing aircraft, as a cutting-edge technology, is not accessible to the public. Its flapping principle is still unknown to most people, and there are very few flapping-wing aircraft used in scientific and educational demonstrations, and the control attitude of the flapping-wing aircraft cannot be displayed in detail during use. In nature, birds During the actual flight, you can freely change the flapping range of the wings to change the magnitude of the lift (for example, a bird needs a large flapping of its wings to generate enough lift when it takes off) so that it can fly freely
However, there are only a handful of flapping wing drive mechanisms that can continuously vary amplitude in the prior art, and they are all relatively complicated, which is not conducive to the in-depth study of the audience.

Embodiment 1

[0023] Depend on Figure 1-3 As can be seen from the illustrated embodiment, the present embodiment includes a posture display platform 8 and a flapping-wing aircraft 9 arranged on the posture display platform 8, and the flapping-wing aircraft 9 includes a bird-shaped fuselage and a flapping-wing drive arranged in the bird-shaped fuselage. Mechanism; attitude display stand 8 includes a floating box and a floating control device, the floating box includes a bottom wall 8-1, a top wall 8-2, a side wall 8-3 and a floating actuator, and the side wall 8-3 passes through the bottom wall 8-1 and the periphery of the top wall 8-2 are closed to form a floating box. At least a part of the side wall 8-3 is made of stretchable cloth material. Part of the side wall 8-3-1, so that the top wall 8-2 is in a relatively floating state, and the floating actuator is arranged in the inner cavity of the floating box. The floating actuator includes a central support rod 8-4, a pitch attitude control...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that the pitch attitude control linear push rod motor 8-5 is arranged on the rear side of the central support rod 8-4, and the roll attitude control linear push rod motor 8-6 is disposed on the central support rod 8 -4 to the right.

[0031] The working principle of the flapping wing drive mechanism:

[0032] When working, the reduction motor 2 drives the adjustable crank 4 to rotate through the coupling 3, and the crank 4 drives the rocker assembly to move. Up and down reciprocating flapping motion.

[0033] The adjustable crank rocker mechanism can drive the slider 4-3 to move in the chute of the crank 4-2 by screwing in or out the adjusting screw 4-4, thereby adjusting the short axis 4 arranged on the slider. -3-1 and the transmission shaft 4-1, changing the effective size of the crank 4-2 can achieve the effect of flapping wings of the flapping wing aircraft.

technical field [0001] The invention relates to the technical field of science and education demonstration. Background technique [0002] As a new concept aircraft of bionic flight, the flapping-wing aircraft has many advantages and broad application prospects. At present, a large number of flapping-wing prototypes have been successfully developed, but the flapping-wing aircraft, as a cutting-edge technology, is not accessible to the public. Its flapping principle is still unknown to most people, and there are very few flapping-wing aircraft used in scientific and educational demonstrations, and the control attitude of the flapping-wing aircraft cannot be displayed in detail during use. In nature, birds In the actual flight process, the flapping range of the wings can be changed at will to change the size of the lift (for example, a bird needs a large flapping of the wings to generate enough lift when taking off) so as to fly freely. However, in the prior art, there are onl...
