Abstract
An exit guide vane array for a turbine engine includes a set of guide vanes 28 having a solidity and defining fluid flow passages 74 with a chordwisely converging forward portion 80. The high solidity and convergent passage portion 80 resist fluid separation. The vanes may also cooperate with each other to restrict an observer's line of sight to planes upstream of the vane array.
Claims15
A turbine engine guide vane array, comprising:
- a set of spanwisely and chordwisely extending guide vanes;
- a fluid flow passage defined between neighboring vanes, each passage having a chordwisely converging forward portion;
- and
- the vane array having a solidity selected to resist fluid separation.
A turbine engine stator vane having a leading end and a trailing end each having a lateral thickness, the lateral thickness of the leading end being approximately equal to the lateral thickness of the trailing end, the vane also having a mean camber line that reverses curvature at least once over at least part of the vane span.
