The question of who invented the second helicopter often leads to a fascinating exploration of early aviation history. While Igor Sikorsky is widely recognized as the “father” of the modern helicopter for his successful VS-300 design in 1939, pinpointing the creator of the second successful helicopter is more complex. It wasn’t a clear-cut race with a definitive second-place finisher. Several inventors were concurrently developing rotary-wing aircraft in the early 20th century, each contributing significant advancements to the field. To understand who might be considered the inventor of the second helicopter, we need to delve into the context of these early innovations.

Beyond Sikorsky: The Pioneers of Vertical Flight
Before Sikorsky’s groundbreaking VS-300, numerous inventors grappled with the challenges of vertical flight. These early pioneers laid the groundwork for Sikorsky’s success and deserve recognition for their contributions. While their machines might not have achieved the same level of sustained, controlled flight as the VS-300, they represent crucial steps in the evolution of the helicopter. One prominent figure in this pre-Sikorsky era is Heinrich Focke.
The Focke-Wulf Fw 61: A Strong Contender for Second Place
Heinrich Focke, a German aviation engineer, developed the Focke-Wulf Fw 61, which first flew in 1936. This twin-rotor helicopter demonstrated remarkable maneuverability and achieved several significant milestones, including altitude and distance records for helicopters at the time. The Fw 61’s successful flights predate Sikorsky’s VS-300, making it a strong contender for the title of the second successful helicopter. The Fw 61 showcased the viability of twin-rotor designs, a configuration still used in many helicopters today.

Other Notable Contributors: A Collaborative Effort
While the Fw 61 presents a strong case, other inventors were also making significant strides in helicopter development during this period. Étienne Oehmichen, a French engineer, developed a series of helicopters in the 1920s, one of which achieved a world record flight of over a kilometer in 1924. Although Oehmichen’s designs were complex and not as practically viable as the Fw 61 or the VS-300, they represent an important step in the journey towards practical helicopter flight. Similarly, Louis Bréguet, another French engineer, developed the Gyroplane Laboratoire, which achieved sustained flight in 1935, further demonstrating the feasibility of rotary-wing aircraft.
Defining “Second”: A Matter of Interpretation
The question of who invented the “second” helicopter hinges on how we define “second.” If we consider sustained, controlled flight and overall design influence, the Focke-Wulf Fw 61 stands out as a strong contender. However, acknowledging the contributions of other pioneers like Oehmichen and Bréguet is crucial. Their work paved the way for later advancements and highlights the collaborative nature of technological innovation. The development of the helicopter wasn’t a singular event but rather a series of breakthroughs built upon the efforts of many dedicated individuals.
Comparison of Early Helicopter Designs and Innovation
The Legacy of Early Helicopter Inventors
The inventors who preceded Sikorsky, while perhaps less well-known, played an indispensable role in shaping the future of aviation. Their tireless experimentation, innovative designs, and unwavering belief in the possibility of vertical flight laid the foundation for the modern helicopter. While the title of “second” may be debatable, the collective contributions of these early pioneers deserve recognition and appreciation. They remind us that innovation is often a gradual process, built upon the successes and failures of those who dared to dream of a future where humankind could take to the skies vertically.
Conclusion: A Shared Victory
Determining who invented the second helicopter is a complex question without a single definitive answer. While the Focke-Wulf Fw 61 makes a compelling case, the contributions of other pioneers like Oehmichen and Bréguet are undeniable. The evolution of the helicopter was a collaborative effort, driven by the ingenuity and persistence of numerous individuals who pushed the boundaries of aviation technology. The legacy of these early inventors continues to inspire engineers and aviators today, shaping the future of vertical flight.
