The Nemeth Parasol: A Roundabout Approach to Flight
Built in 1934, this wacky looking aircraft featured a circular wing, designed to improve stability and stall resistance. Despite promising flight tests, this concept never reached mass production.
So what was the purpose of this flying saucer-shaped plane, and why didn’t it catch on?
What Was the Big Idea?
The Nemeth Parasol was designed by Steven P. Nemeth, an aeronautical engineer who wanted to explore alternative wing configurations that could improve low-speed handling and stall resistance.
At the time, traditional aircraft wings had significant limitations, especially at low speeds. Pilots often struggled with maintaining control during takeoffs and landings, increasing the risk of stall-related crashes. Nemeth believed that a circular wing could mitigate this issue by:
✔ Providing more uniform lift distribution compared to conventional wings.
✔ Reducing the severity of stalls and making slow-speed flight safer.
✔ Allowing for shorter takeoff and landing distances, making flying more accessible.
The Nemeth Parasol was built using a modified Alliance Argo biplane fuselage and was powered by a Warner Scarab radial engine. While its appearance was unusual, it successfully took flight, proving that a circular wing could generate stable lift and maintain control at low speeds.

What Was the Purpose?
The Nemeth Parasol was an experimental aircraft designed to explore how circular wings could improve flight stability and safety. The potential benefits included:
✔ Improved Stall Resistance – The design aimed to reduce abrupt stalls, improving low-speed control and safety.
✔ Short Takeoff and Landing (STOL) Potential – The aircraft generated high lift, allowing for shorter takeoff and landing distances than conventional planes of similar size.
✔ Simplified Handling – The circular wing provided better stability, which could have made flight more accessible for less experienced pilots.
Although the Nemeth Parasol was not built as a performance aircraft, it was envisioned as a potential step toward safer, more forgiving aircraft designs.
Why Was It Never Mass Produced?
Despite promising test flights and functional aerodynamics, the Nemeth Parasol never entered mass production for several reasons:
The Circular Wing Concept Was Too Radical
- In the 1930s, the aviation industry was focused on streamlined monoplanes with proven aerodynamics.
- The circular wing was considered too unconventional, and manufacturers were reluctant to invest in a design that deviated so drastically from standard aircraft configurations.
Limited Performance Advantages
- While the Nemeth Parasol demonstrated good low-speed handling, it was not particularly fast or efficient at higher speeds.
- The drag created by the circular wing limited its potential for long-distance flight or commercial viability.
- Other aircraft designs emerging at the time provided similar safety benefits with better overall performance.
No Commercial or Military Market
- Unlike later aircraft with STOL capabilities, the Nemeth Parasol was never marketed as a practical aviation solution.
- While the concept was intriguing, manufacturers saw no viable market for production.
World War II Shifted Aviation Priorities
- By the late 1930s and early 1940s, aviation priorities shifted toward military aircraft development.
- Experimental designs like the Nemeth Parasol were overshadowed by the demand for high-speed fighters, bombers, and long-range transport aircraft.
Ultimately, the lack of market interest, limited performance advantages, and its eccentric appearance meant that the Nemeth Parasol remained a one-off experiment rather than a breakthrough in aviation design.

What’s the Takeaway?
Although it never saw mass production, the Nemeth Parasol contributed valuable insights into alternative wing designs and flight stability. Its concept continues to influence modern aerodynamics, particularly in low-speed aircraft and UAVs. Key takeaways include:
✔ Circular Wing Designs Have Merit – The Nemeth Parasol’s lifting-body concept has been revisited in modern aviation research, particularly in VTOL (Vertical Takeoff and Landing) aircraft and UAVs.
✔ Low-Speed Handling Remains a Design Priority – Modern STOL aircraft, UAVs, and experimental planes continue to explore the principles Nemeth envisioned—stable, low-speed flight with improved stall resistance.
While the Nemeth Parasol was too ahead of its time, it remains a fascinating example of creative aviation engineering and the willingness to challenge traditional design principles.
Conclusion:
The Nemeth Parasol may not have revolutionized aviation, but it proved that thinking outside the box deserved exploration. While its circular wing design never became mainstream, its core principles—stall resistance, stability, and improved control at low speeds—remain relevant in modern aviation.
This unique aircraft serves as a reminder that progress in aviation requires both bold innovation and practical acceptance—a delicate balance that only a few experimental designs achieve.
Even though it was a one-of-a-kind aircraft, the Nemeth Parasol stands as a testament to bold thinking and the never-ending quest to improve flight.
