wherein the engine further includes:

an engine core comprising a turbine, a compressor, and a core shaft connecting the turbine to the compressor, and

a core casing surrounding the engine core;

wherein the support structure includes:

an engine-side interface member positioned outwardly of, and radially spaced from, the core casing, the engine-side interface member extending circumferentially around a top half of the core casing from a bottom end of the engine-side interface member on one side of the core casing to an opposite bottom end on the opposite side of the core casing,

a pylon-side interface member configured to join to the front connection face and interfacing to the engine-side interface member, the pylon-side interface member also extending circumferentially around the top half of the core casing, and

a top V-shaped connection formation positioned above the engine core and pair of side V-shaped connection formations positioned on opposite lateral sides of the engine core, each V-shaped connection formation being formed by a pair of connection members meeting at a vertex, the vertex of the top V-shaped connection formation joining to the top of the engine-side interface member, the vertices of the side V-shaped connection formations respectively joining to the bottom ends of the engine-side interface member, and the connection members extending forwardly from their respective vertices to join to respective front fixation points at the core casing; and

wherein the engine-side interface member and the pylon-side interface member are joined by plural circumferentially spaced connective links configured so as to transfer roll torques from the engine to the pylon.
