Fan case assembly of turbo fan engine

A fan case assembly of a turbo fan engine,

• the fan case assembly comprising:
• a tubular fan case surrounding a fan of the turbo fan engine from an outside in a radial direction;
• a tubular panel set covering an inner peripheral surface of the tubular fan case such that a radial gap is formed overall between the tubular fan case and the tubular panel set, the tubular panel set including panels lined up in an axial direction of the turbo fan engine;
• and
• at least one elastic body compressed by two members selected from the tubular fan case and the panels, wherein:
• a linear expansion coefficient of the tubular fan case and a linear expansion coefficient of the tubular panel set are different from each other;
• the at least one elastic body includes a radial elastic body compressed by the tubular fan case and the tubular panel set in the radial direction;
• and
• the radial elastic body is a plate spring extending in the axial direction,
• the radial elastic body includes
• an attaching portion attached to one of the tubular panel set and the tubular fan case,
• an elastic portion that projects in the radial direction and compressed by the other of the tubular panel set and the tubular fan case in the radial direction, and
• an end portion that is on the opposite side in the axial direction to the attaching portion and is slidable in the axial direction,
• wherein one of the two members includes a stopper that limits elastic deformation of the radial elastic body;
• the stopper is located such that when the elastic portion is pressed radially, the end portion slides in the axial direction so as to approach the stopper and then the end portion contacts the stopper.
