Abstract
A gas turbine engine comprises a fan on an engine central axis. Plural gas generators are downstream of the fan, each along a respective central axis, mutually offset, and offset from the engine central axis. A fan drive turbine is on the engine central axis, downstream of the dual gas generators, and driven by output from the dual gas generators, to drive the fan.
Claims11
A gas turbine engine comprising:
- a fan on an engine central axis;
- plural gas generators downstream of the fan, each along a respective central axis that are mutually offset and non-parallel to the engine central axis and extend at a gas generator angle with respect to the engine central axis, wherein a gas generator forward end is closer to the engine central axis than a gas generator aft end;
- and
- a fan drive turbine on the engine central axis, downstream of the plural gas generators, and driven by products of combustion downstream from the plural gas generators, for driving the fan;
- wherein said plural gas generators each include a generator exhaust duct to deliver the products of combustion into an exhaust housing and across said fan drive turbine;
- and
- said generator exhaust ducts extend at a generator exhaust duct angle relative to said engine central axis, wherein a generator exhaust duct aft end is closer to the engine central axis than a generator exhaust duct forward end, and
- wherein the generator exhaust duct angle is greater than the gas generator angle.
