Abstract
Inlet guide vanes and gas turbine engine systems involving such vanes are provided. In this regard, a representative an inlet guide vane for a gas turbine engine includes: a fixed strut; and a variable flap located downstream of the fixed strut and being movable with respect thereto; the fixed strut having a leading edge, a trailing edge and side surfaces extending between the leading edge and the trailing edge, the side surfaces being asymmetric with respect to each other.
Claims20
An inlet guide vane for a gas turbine engine comprising:
- a fixed strut;
- and
- a variable flap located downstream of the fixed strut and being movable with respect thereto;
- the fixed strut having a leading edge, a trailing edge and side surfaces extending between the leading edge and the trailing edge, the side surfaces being assymetric with respect to each other.
An inlet guide vane assembly for a gas turbine engine comprising:
- multiple inlet guide vanes;
- a first of the inlet guide vanes having a fixed strut and a variable flap;
- the variable flap being located downstream of the fixed strut and being movable with respect thereto;
- the fixed strut exhibiting chordwise asymmetry operative to reduce a tendency of gas flowing along surfaces of the inlet guide vane to separate therefrom.
A gas turbine engine comprising:
- a compressor section having an inlet guide vane assembly, a set of rotatable blades and a set of stationary vanes;
- the inlet guide vane assembly being located upstream of the set of rotatable blades and the set of stationary vanes, the inlet guide vane assembly having multiple guide vanes;
- a first of the guide vanes having a fixed strut and a variable flap, the variable flap being located downstream of the fixed strut and being movable with respect thereto, the fixed strut having a leading edge, a trailing edge and side surfaces extending between the leading edge and the trailing edge, the side surfaces being asymmetric with respect to each other.
