A bleed valve system for a gas turbine engine including an unducted fan having unducted fan blades rotatable about a longitudinal centerline and unducted fan guide vanes not rotatable about the longitudinal centerline, the bleed valve system comprising:
- a bleed valve;
- a bleed valve exhaust duct fluidly connected to the bleed valve;
- and
- a bleed valve exhaust nozzle fluidly connected to the bleed valve exhaust duct,
- wherein the bleed valve exhaust duct and the bleed valve exhaust nozzle are fluidly separated from a gas turbine engine exhaust nozzle when the bleed valve system is installed in the gas turbine engine.
A gas turbine engine defining a radial direction, the gas turbine engine comprising:
- a turbomachine including a turbomachine exhaust nozzle;
- a fan section including an unducted fan having unducted fan blades rotatable about a longitudinal centerline and unducted fan guide vanes not rotatable about the longitudinal centerline, a fan duct, and a fan exhaust nozzle;
- and
- a bleed valve system comprising:
- a bleed valve fluidly connected to the turbomachine;
- a bleed valve exhaust duct fluidly connected to the bleed valve;
- and
- a bleed valve exhaust nozzle fluidly connected to the bleed valve exhaust duct,
- wherein the bleed valve exhaust duct and the bleed valve exhaust nozzle are fluidly separated from the turbomachine exhaust nozzle and the fan exhaust nozzle.
