Before, I saw someone send a circle of friends saying: days are mixed, resumes are fake, offer is cheated, defense is water, only time is true! Indeed, only time is true. It makes me feel more and more small. I am eager to verify whether I am suitable for the design industry. However, I am afraid that if I do not design, what else can I do?! Don't ask me anything. I don't know what I 've done. I don't know what I 've learned in my four years of college?!

Drawing on the research of the Federal Institute of Technology in Lausanne, Switzerland, inspired by birds. The wings of birds are divided into main wings and ailerons. The folding and unfolding of the ailerons can change the lift and windward resistance of the wings. Coupled with the cooperation of the tail feathers, the birds can be flexible and free in different flying environments. Strong adaptability. This project starts with the folding wings and overall shape of the UAV, and puts the wings of birds on the UAV so that it can perform better flight performance. The product is positioned as a small civilian drone, suitable for low altitude environments.

The deformation mode is designed, and the motor is pulled and the spring is returned.

The feathers of the drone's secondary feathers are connected by a parallelogram mechanism, and the sweep angle after folding is 45 °

Fuck! The size calculation was wrong, and the effect after 3D printing did not reach the ideal state (although the ideal state effect was not good 233), and it had to be readjusted.

Because the motor needs to be installed inside (only folding wing movement, the flight system cannot do 233), the fuselage is widened, which is far from the original. The color chosen for painting is not ideal either. I think this is the ugliest model I have made... But the folding wing is realized.

Looking at other people's settings, I feel that I am too low, but I still want to commemorate that I will leave the school where I stayed for four years in two days. I am really not willing to give up, but people always have to face it. I will adjust my mind to work well, or use real time to test myself.
