摘要： PROBLEM TO BE SOLVED: To provide an inexpensive turbine engine with simple molding.
SOLUTION: The turbine engine having a rotational shaft B includes a fan cover 10 and a fan V with movable vanes 17. A space extends between an inner face of the cover and free edges of the vanes. A bearing of the fan is connected with a fixed part of the turbine engine with a connecting part in which a rotational shaft of the fan oscillates around the rotational shaft B as a center when the bearing is broken if load is applied to the vanes of the fan. The cover includes a thermoformable foam layer 12 bonded to its inner face and a part of a range of the space, and is arranged to face edges of the vanes 17 of the fan V. The thermoformable foam layer 12 is partially coated with an abradable substance layer 14, so that the free edges of the vanes at least partially fragments the abradable substance layer 14 when load acts on the fan.
