The Nemeth Parasol
Steven P. Nemeth, an inventor and former flight instructor, designed the Parasol. Students at the Miami University manufactured Nemeth’s design. The Parasol is the first circular winged aircraft.
In 1934, the Parasol launched into the air for its first flight. Onlookers labelled the aircraft a flying umbrella. Nemeth piloted the Parasol at speeds of 135 mph.
In midair, Nemeth intentionally extinguished the motor. The Parasol’s circular wings balanced the aircraft. The Parasol gently parachuted nearly vertically.
The aircraft succeeded in its flight trials. One redesign improved the only Parasol prototype before the project halted. There’s limited information on why supporters abandoned the Parasol.
