Dynamic biomimetic flapping butterfly Introduction to biomimetic butterflies:
The design concept of the aircraft: The wing ribs and proportions are improved based on the design of a real butterfly. The wings are made of nylon fabric and carbon fiber materials to generate specific thrust based on the deformation of the wings. The definition of flight is achieved on the basis of low frequency, low speed and biomimicry, and the control of throttle, lift and direction is formed according to the angle changes of the wings. Extreme lightweight flight can achieve vertical climb.
Biomimetic butterfly parameters:
Flight weight is about 59g
Wing span of about 75cm
The body is about 50cm
Maximum load capacity 25g
Environmental flight requires quiet indoor or outdoor wind (wind has a significant impact, indoor is recommended)
Applicable scenarios include personal flights, events, performances, visits, training, weddings, large-scale exhibitions, and more
