The present invention discloses a driving device for connecting with a propeller. The driving device includes a body portion and a driving shaft disposed at the body portion and rotatable relative to the body portion. The driving device further includes an elastic abutting member disposed on the body portion and a lock portion disposed on the body portion. The lock portion is provided thereon with at least one first snap-fitting portion for being clamped with the propeller. The elastic abutting member is used for abutting against the propeller when the first snap-fitting portion is snapped with the propeller. The present invention further relates to a propeller and a propulsion system.

摘要:
A propeller propulsion assembly for an aircraft has a transmission shaft (2), which extends along an axis (3) and ends with an attachment portion (4) on which a propeller is mounted; the shaft (2) is driven by a transmission device (29) having a first body (15) coaxial and rotating relative to the shaft (2), a second body (6) coaxial and angularly fixed relative to the shaft (2) and an elastic device (8) exerting a thrust on the second body (6) to arrange said bodies in a reference position and compensate relative angular movements around said reference position. The assembly (1) further comprises a clutch (5) which is normally engaged to transmit drive torque to the first body (15) and is configured so as to automatically disengage when the resulting torque becomes a braking torque and exceeds a given threshold.
摘要:
A propeller shaft assembly having a propeller shaft member defining an inner volume. A foam liner member is disposed in at least a portion of the inner volume of the propeller shaft member. The foam liner member is made of a viscoelastic, natural oil polyol-based foam, whereby the foam liner member is operable to reduce vibration amplitudes occurring within the propeller shaft member relative to an undampened propeller shaft member.

An aircraft is provided with a gas turbine engine having a plurality of shafts. A first shaft provides power to an electrical generator and a propeller, while a second shaft provides power to a refrigeration system. The refrigeration system may be integrated to the propeller, like a ducted fan, or on the outer skin of the aircraft.
