Abstract
A gas turbine engine, comprising a fan driven by a fan shaft and retractable axial retainer of the shaft mounted on a stator element and movable between a first operational position and a second non-operational position. The retainer may comprise a fluid supply configured for supplying at least one cavity with fluid. In some examples, the retainer is mounted movable or slidingly so as to generate movement of the retainer between the operation and non-operational positions.
Claims20
A gas turbine engine, comprising a fan driven by a fan shaft and retractable axial retention means for said shaft mounted on a stator element and movable between a first operational position and a second non-operational position, wherein said retention means comprises means for supplying fluid to at least one cavity wherein said retention means is movably mounted so as to generate movement of the retention means between said first operational position and said second non-operational position.
A gas turbine engine, comprising:
- a fan driven by a fan shaft;
- and
- a retractable axial retainer associated with said fan shaft and mounted for movement on a stator element, the retractable axial retainer being movable between a first operational position and a second non-operational position, wherein the retractable axial retainer comprises a fluid supply configured to supply fluid to at least one cavity in which said retainer is mounted for movement so as to generate the movement of the retainer between said first operational position and said second non-operational position.
