Method and system for a stowable bell-mouth scoop

A turbofan engine defining an axial direction, a radial direction, and a circumferential direction, the turbofan engine comprising:

• a core turbine engine configured to generate a stream of high energy exhaust gases;
• a fan powered by a power turbine driven by the high energy exhaust gases;
• a fan bypass duct at least partially surrounding said core turbine engine and said fan;
• and
• a bell-mouth scoop assembly coupled to an aft end of said fan bypass duct, the bell-mouth scoop assembly comprising:
• a plurality of hinge members configured to rotate in unison about a respective hinge axis of rotation from a first stowed position to a second deployed position;
• at least one linkage arm extending outwardly from at least one of the plurality of hinge members, said linkage arm comprising a first hinge connection end, a second panel connection end, and a body extending therebetween;
• and
• a bell-mouth panel comprising a panel longitudinal centerline and pivotably coupled to each at least one linkage arm,
• wherein, in the first stowed position, said bell-mouth panel is configured to conform to an outer surface of said fan bypass duct with the panel longitudinal centerline aligned with the circumferential direction about a circumference of said fan bypass duct, and
• wherein, in the second deployed position, said bell-mouth panel is configured to extend away from said outer surface of said fan bypass duct with the panel longitudinal centerline having a larger component in the axial direction than in the radial direction or the circumferential direction.
