- Summary
- Charles M. Olmsted, a European trained physicist from Upstate New York, had an interest in flight from his early years. His success with gliders in the 1890's led to the formation of the Buffalo-Pitts-Olmsted Syndicate in 1910 to develop aircraft. Following failure of the related agricultural equipment manufacturing company, Olmsted formed the CMO Physical Laboratory, continuing to manufacture and sell his ultra-efficient propellers.
- Olmsted propellers had a significant role in aviation history, including weight carrying records and the first transatlantic aircraft flight, but differed from other propellers, having a large surface near the blade base and very little surface at the tip. Olmsted's propellers represented a fundamental difference in design philosophy that has not been duplicated by any other designer.
- This particular left-turning pusher propeller was used in over-power testing, resulting in a glue joint opening up, and was donated to the museum by the designer along with other artifacts.
