DEVICE AND METHOD EMPLOYING A TURBINE FOR CONTRIBUTING THRUST TO A PROPELLER ON A SPINNER

摘要

Turbine (14) is added to the spinner (12) of a propeller (10) to provide a contribution to propulsive thrust of the propeller (10). The turbine (14) comprises a group of turbine modules (14a) which are mounted on the peripher y of the spinner (12) between root portions of the propeller blades (10b). Eac h module (14a) includes a curved row of angulated turbine vanes (16) held between a curved base plate (18) and a curved outer plate (20).
