SUPPORT STRUCTURE FOR ATTACHING A GAS TURBINE ENGINE TO AN AIRCRAFT PYLON

A gas turbine engine (10) includes a support structure (43) for attaching the engine (10) to an aircraft pylon (13). The support structure (43) includes: an engine-side interface member (31), a pylon-side interface member (33) interfacing to the engine-side interface member (31), and a top V-shaped connection formation (37) positioned above the engine core (11) and pair of side V-shaped connection formations (39) positioned on opposite lateral sides of the engine core (11), each V-shaped connection formation (37, 39) being formed by a pair of connection members meeting at a vertex, the vertex of the top V-shaped connection formation (37) joining to the top of the engine-side interface member (31), the vertices of the side V-shaped connection formations (39) respectively joining to the bottom ends of the engine-side interface member (33), and the connection members extending forwardly from their respective vertices to join to respective front fixation points at the core casing (42).
