Abstract: PROBLEM TO BE SOLVED: To provide an inlet guide vane flap with increased partial-speed operability and flutter margin, thus avoiding fan rotor mistuning at particular operational conditions. SOLUTION: A variable-shape inlet guide vane (IGV) system 46 includes the variable-shape inlet guide vane flap 48 provided with a flexible part 64 that enables the desired spanwise distribution of axial velocities Cx, α, and β at an inlet of the fan rotor 30. The flexible part 64 is formed of a flexible material such as silicone rubber combined with internal reinforcing fibers or filaments. The form of the flap 48 is not symmetric, but twisted during actuation from the maximum opening position to the maximum closed position. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: A gas turbine engine includes a propulsion unit mounted to rotate about a first axis, and a core engine mounted to rotate about a second axis, and wherein the first and second axes are non-parallel. A gas turbine engine includes a propulsion unit driven by a free turbine which is adjacent to the propulsion unit and an associated fan, and having a gas generator core engine including a compressor, combustor and turbine section. A method is also disclosed.
