Abstract
An aircraft engine apparatus (1) includes: a rotating shaft (6); a fan (10) driven by the rotating shaft; a fan case surrounding the fan from outside in a radial direction of the rotating shaft; a nose cone (13) disposed upstream of the fan; a casing (2) that accommodates at least part of the rotating shaft and supports the fan case; a first motive force transmitter (9) that transmits motive force of the rotating shaft to the fan; and a support member (12) disposed inward of the first motive force transmitter in the radial direction, the support member coupling the nose cone to the casing such that the support member supports the nose cone in a stationary state.
Claims10
An aircraft engine apparatus comprising:
- a rotating shaft;
- a fan that includes a fan hub and a plurality of fan blades coupled to the fan hub such that the fan blades are arranged at intervals in a circumferential direction and extend in a radial manner, the fan being driven by the rotating shaft;
- a fan case surrounding the fan from outside in a radial direction of the rotating shaft;
- a nose cone disposed upstream of the fan;
- a casing that accommodates at least part of the rotating shaft and supports the fan case;
- a coupling member that transmits motive force of the rotating shaft to the fan and is a hollow member extending in an axial direction of the rotating shaft;
- a transmission that is disposed downstream of the fan and couples the rotating shaft to the coupling member;
- and
- a support member disposed inward of the coupling member in the radial direction, the support member coupling the nose cone to the casing such that the support member supports the nose cone in a stationary state.
