Igor Sikorsky is recognized as the father of the modern helicopter, but what may not be as widely known is how he gathered the information that led to its development. This is the story of helicopters and dragonflies.
Sikorsky dedicated years to observing birds and insects to understand how to achieve stable, controlled flight. Dragonflies stood out because their wings operate independently, each capable of rotating, tilting, and shifting angles to produce quick changes in lift.
As helicopter technology has advanced, engineers continue to draw inspiration from the dragonfly. Its sideways dashes, backward flight, sudden stops, and precise hovering are still studied by engineers. Even the dragonfly’s timing patterns, rotational wing strokes, and quick lift adjustments have been emulated to improve the stability of helicopter rotor systems.
Dragonflies offer a blueprint for aerial agility, and their design is an engineering marvel. The big question is how the dragonfly’s design came about. It seems impossible to explain this complexity as the result of random chance. It appears to be a design from a Master Engineer.
Helicopters and dragonflies serve as another example of biomimicry and provide evidence that all life is a product of intelligence, demonstrating the truth of Romans 1:20 that we can know there is a God through the things He has made. as made.
