Shrouded rotary assembly from segmented composite for aircraft and method for its manufacture |
摘要 |
The invention relates to a shrouded rotor assembly (B) for an aircraft (A). The shrouded rotor assembly (B) comprises a stator hollow structure comprises formed from a plurality of composite angular segments (9). Each composite angular segment (9) includes: a core arched section (10) of a central hub casing (3), a peripheral rim section (11) of an external hollow duct (5) and a pair of angularly opposed sliced portions (12), respectively for one of a pair of guide vanes (6). The resulting stator hollow structure (H) is a unitary one-piece, integrating together continuously the composite angular segments (9). The invention typically applies e.g. to aircrafts (A) such as rotary wing aircrafts. |
