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).

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.

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 ...

Chlorofluorocarbon (CFC) propellants used in metered dose inhalers (MDI) must be replaced under the terms of the Montreal Protocol. Following a review of the available data, HFA134a (1,1,1,2 tetrafluoroethane) was selected as a potential alternative propellant.

This report summarizes the available information on the toxicity of 15 propellants used in aerosols. After reviewing the results derived from various animal species, the following classifications are proposed: Low-pressure propellants of high toxicity: trichlorofluoromethane (FC 11), dichloromonofluoromethane (FC 21), trichlorotrifluoroethane (FC

Propeller Induced Velocities in Ducted Propellers
SNAME Propellers '84 Symposium, 1984This paper presents the results of flow measurements in the nozzle opening of ducted propellers operating in both open and behind conditions. The open-water test measurements show the propeller induced velocities in nozzle opening differ from the results from conventional propeller measurements.
