VARIABLE GEOMETRY AND SELF-ACTUATING SWIRLING DEVICE.

摘要

The present invention relates to a variable geometry swirl device (60) that includes a variable geometry, self-actuating vane system for initially mixing fuel and air. The swirl device (60) has a plurality of swirl vanes (84) made of a temperature sensitive material, these vanes being movable between open and closed positions as a function of temperature when the swirl vanes (84) are subjected to heat.
