After the interim crit, I researched on maple seeds Max has mentioned.
Maple seeds, of which shape is designed to fly far has a relation to the idea of spinning. In fact, it has what to be the best elements to fly in the way I want my plane want to fly. It was fascinating to see how the nature has all the elements of what we constantly seek for.
According to an article, the logic behind them is this.
"By swirling, maple seeds generate a tornado-like vortex that sits atop the front leading edge of the seed as they spin slowly to the ground. This leading-edge vortex lowers the air pressure over the upper surface of the maple seed, effectively sucking the wing upward to oppose gravity, giving it a boost. The vortex doubles the lift generated by the seeds compared to nonswirling seeds."
"When maple seeds become airborne they pick up downward speed and start to spin around their center of gravity, which is located in the nut. This spinning motion is induced by the airflow around the seed as it descends to the ground. Because the spinning, helicopter-like, motion of the maple seeds arises automatically, it is called autorotation. The autorotation slows down the descent of the seed such that the seed can be carried further away from the tree by wind. (Credit: David Lentink)"
