Abstract
Gas turbine engine systems involving variable nozzles with sliding doors are provided. In this regard, a representative door assembly for a gas turbine engine includes: a door configured for alignment with an exit area of a nozzle and operative to variably open and close the nozzle exit area such that gas directed along a gas path defined, at least in part, by the nozzle exit area is regulated
Claims20
A door assembly for a gas turbine engine, the door assembly comprising:
- a door configured for alignment with an exit area of a nozzle and operative to variably open and close the nozzle exit area such that gas directed along a gas path defined, at least in part, by the nozzle exit area is regulated.
A nozzle assembly for a gas turbine engine, the nozzle assembly comprising:
- a nozzle defining a nozzle exit area;
- and
- a door operative to selectively increase and decrease an effective size of the nozzle exit area.
A gas turbine engine comprising:
- a compressor;
- a turbine operative to drive the compressor;
- and
- a nozzle assembly positioned downstream of the turbine, the nozzle assembly defining an exit area and having a door operative to move between an open position, at which the nozzle assembly exhibits a maximum exit area, and a closed position, at which the nozzle assembly exhibits a minimum exit area.
