Full ring sliding nacelle with thrust reverser

A gas turbine engine comprising:

• a fore pylon;
• a first annular portion that is stationary and adapted for partially surrounding an engine core, the first annular portion including a fore pylon connecting portion;
• a rail coupled to the fore pylon and extending in an aft direction from the first annular portion;
• a second annular portion, aft of the first annular portion and coupled to the rail, the second annular portion being movable along an engine core centerline between a closed position and at least one open position, wherein the second annular portion is configured to engage the first annular portion in the closed position, thereby preventing access to the engine core;
• and
• a thrust reverser arranged in the second annular portion, wherein the thrust reverser is a pivot thrust reverser comprising:
• a first tandem pivot door subassembly;
• a second tandem pivot door subassembly;
• an actuator connected to the second annular portion, the actuator being oriented parallel to the engine core centerline;
• a first linkage of the first tandem pivot door subassembly;
• and
• a second linkage of the second tandem pivot door subassembly;
• wherein each of the first linkage and the second linkage are connected to the actuator which pivots the first tandem pivot door subassembly and the second tandem pivot door subassembly on respective pivot axes that are positionally fixed with respect to the second annular portion;
• wherein the first tandem pivot door subassembly comprises a first inner panel and a first outer panel, wherein the first inner panel and the first outer panel are connected by a first sliding rail that extends from one of the first inner panel and the first outer panel and is in contact with the other one of the first inner panel and the first outer panel, such that the first inner panel slides along the first outer panel when the first tandem pivot door subassembly is being deployed and stowed;
• wherein the second tandem pivot door subassembly comprises a second inner panel and a second outer panel, wherein the second inner panel and the second outer panel are connected by a second sliding rail that extends from one of the second inner panel and the second outer panel and is in contact with the other one of the second inner panel and the second outer panel, such that the second inner panel slides along the second outer panel when the second tandem pivot door subassembly is being deployed and stowed;
• and
• wherein each of the first tandem pivot door subassembly and the second tandem pivot door subassembly respectively surround substantially half of the engine core when deployed.
