He considered air as a fluid resisting flight and presented the idea that birds fly by beating their wings and “condensing” the air under the wings. Using this concept of beating wings to pressurise air, he developed a design for an “ornithopter” – a flying machine that achieves flight by flapping it’s wings.
Why did Leonardo Da Vinci invent the helicopter?
In the late 1400s, Leonardo da Vinci created his aerial screw drawing in his notebook. Because da Vinci was so observant of nature and his surroundings, it is believed this design was partly based on his observations of the spinning of maple seeds as they fall to the ground.

Da Vinci seemed truly excited by the possibility of people soaring through the skies like birds.
