Leonardo da Vinci was a brilliant inventor and artist from the 15th century who dreamed of creating machines that could fly. Even though the technology back then wasn’t advanced enough to make his ideas a reality, his designs showed how creative and ahead of his time he was.
One of Leonardo’s most famous flying machine ideas was the ornithopter. This machine was designed to fly by flapping its wings, much like a bird or a bat. While Leonardo wasn’t the first to think of such a device—similar ideas appeared in ancient texts like the Ramayana—his design was unique. He studied how birds and bats flew and tried to mimic their movements. He once said, “Human subtlety will never devise an invention more beautiful, more simple, or more direct than does nature; because in her inventions, nothing is lacking and nothing is superfluous.”
In Leonardo’s ornithopter design, the pilot would lie face down on a wooden board. The wings, made of pine and raw silk, would be 33 feet wide. The pilot would use a pedal crank and a system of rods and pulleys to flap the wings. Steering was controlled by a headpiece, and a hand crank could give extra power. However, Leonardo likely realized that no human could generate enough power to lift off the ground.
Leonardo also came up with an idea for a helicopter-like machine called the helical airscrew. This design included a circular platform for pilots, a long shaft, and a large screw-shaped canopy made of starched linen. The pilots would twist cranks to spin the shaft and, in theory, create lift. Unfortunately, the technology of Leonardo’s time couldn’t build a working version, and modern tests have shown that the design was too heavy to fly.
Leonardo’s parachute design was perhaps his most successful aviation-related invention. He believed that a person could safely jump from any height using a large piece of linen. His sketch showed a person hanging from a pyramid-shaped canopy supported by a wooden frame. The base of the frame was 12 by 12 yards, with four poles meeting at a point above. Like his other flying machines, this parachute was never built during his lifetime.
Leonardo da Vinci’s flying machines were never realized, but they continue to inspire people today. His work reminds us of the power of imagination and the endless possibilities of human creativity.
Using simple materials like paper, straws, and rubber bands, create a model of Leonardo’s ornithopter. Experiment with different wing shapes and sizes to see how they affect flight. Discuss with your classmates how Leonardo’s design compares to modern flying machines.
Imagine you are an inventor like Leonardo. Sketch your own design for a flying machine using today’s technology. Consider what materials and power sources you would use. Present your design to the class and explain how it improves upon Leonardo’s concepts.
Research the principles of flight, such as lift, thrust, drag, and gravity. Create a presentation or poster that explains these concepts and how they relate to Leonardo’s flying machines. Share your findings with the class.
Construct a simple parachute using a plastic bag, string, and a small weight. Test it by dropping it from a height and observe how it slows the descent. Compare your parachute’s design to Leonardo’s and discuss the effectiveness of different shapes and materials.
Take a virtual tour of a museum or online exhibit featuring Leonardo da Vinci’s inventions. Write a short report on how his flying machines influenced modern aviation. Discuss what you found most surprising or inspiring about his work.

Leonardo da Vinci’s flying machines were among his most inspired inventions, particularly in the field of aviation. Despite the technological limitations of the 15th century and some flawed designs, da Vinci’s flying machines showcased a scientific and creative mind that was far ahead of many of his contemporaries.
One of the most well-known of da Vinci’s inventions is the ornithopter. Unlike fixed-wing aircraft, the wings of an ornithopter flap up and down, similar to those of a flying animal. Da Vinci was not the first to conceive of such a device; the earliest description of an ornithopter can be found in the Ramayana, written between the 5th and 1st centuries BC. There were several attempts at flight before da Vinci’s time, but these were likely limited to sustained glides rather than true flight.
For inspiration, da Vinci looked to nature, basing his design on the flight of bats and birds. He famously stated, “Human subtlety will never devise an invention more beautiful, more simple, or more direct than does nature; because in her inventions, nothing is lacking and nothing is superfluous.” In his ornithopter design, the pilot would lie face down on a wooden board at the center of the device. The frame would be made of pine and raw silk, with wings spanning 33 feet, powered by a pedal crank and a rod and pulley system. Steering would be facilitated by a headpiece, and a hand crank would provide additional power if needed.
Although there is no evidence that the device was ever built or tested during da Vinci’s lifetime, it is likely he recognized a significant flaw: while sustained flight might be possible, no single human could generate the power necessary for takeoff.
Da Vinci’s helical airscrew is often considered the first attempt at designing a fully operational helicopter, although it bears little resemblance to modern helicopters. The design consisted of a circular platform for pilots, a long shaft, and a large screw-shaped canopy made of starched linen. The pilots would power the device by twisting cranks to rotate the shaft and theoretically create lift. Despite demonstrating a clear understanding of the physics of flight, the technology of the late 15th century was not advanced enough to construct a functional machine. Modern reconstructions have shown that the design was too heavy to achieve flight.
Perhaps the most successful of da Vinci’s aviation-related inventions is his parachute. He believed that a person could safely jump from any height using a large enough piece of linen. His sketch depicted a person suspended from a pyramid-shaped canopy, supported by a wooden frame measuring 12 by 12 yards at the base, with four poles rising to a central point. Like his other flying machines, da Vinci’s parachute remained entirely conceptual throughout its lifetime.
