Rotating propeller soliton

Nonlinear Guided Waves and Their Applications, 2001
We demonstrate experimentally and theoretically (both analytically and numerically) a new type of spatial soliton: a rotating "propeller" soliton. This is a composite soliton made of a rotating dipole component jointly trapped with a bell-shaped component. We observe as much as 239 degrees of rotation over 13 mm of propagation (6.5 diffraction lengths).

Propeller Injuries

Southern Medical Journal, 1976
Water skiing, boat racing, skin and scuba diving, and pleasure boat cruising are increasing in popularity. As a result the incidence of injuries secondary to motor propellers is becoming more frequent. In a ten-year period from 1963 to 1973, I collected a total of nine cases.

Return of the Propeller

Scientific American, 2014
The article discusses research into turboprops being driven by a demand for shorter, cheaper airplane flights. Topics include a brief historical overview of the debut of propeller-driven aircraft, the fuel efficiency of turboprops, compared to turbofans, and engineers at General Electric Aviation's Dowty Propellers, who are using computational fluid ...
