Device for generating a recirculating flow

摘要

A propeller (1) has baffles (air guides) (7) which are arranged upright on the pressure side of its propeller blades (3, 4, 5) and, seen in the axial direction, extend in an outwardly curved fashion and stabilise the flow in the axial direction. As a result, subsidiary flows which deviate from the axial direction are prevented without the need for a separate flow-guiding tube as previously employed. <IMAGE>
