摘要： The present invention refers to a fixed pitch type propeller for vessels, fitted with exchangeable blades and having a central core unit that can be coupled to the transmission receiving the movement from the corresponding engine, and a plurality of blades that surround it in an equiangular distribution and are affixed to the central core; said core (1) has a prism-like configuration with as many faces as blades (2), each of its lateral faces having a groove 6 that ends in a narrowed mouth opening, while the inner ends of blades 2 are each topped by a header (4) that can be coupled to one of the lateral faces of the core unit (1) and fitted midway with a rib (7) that is complementary to the groove (6). The invention also provides means for axial immobilization (3 - 8) of the headers (4) of the blades respective to the core unit (1).

摘要： A marine propeller drive (1) for boats, including a gearbox (10) for a motor transmission and an associated impelling propeller (12), where said propeller (12) is provided with a propeller hub (14), the main peripheral cross-section dimension (A) of which is less than the main peripheral cross-section dimension (B) of the gearbox (10) and where a transition cone (18) is located between the gearbox (10) and the propeller hub (14). The transition cone (18) has: - a front end (20) located in connection with the gearbox (10), where said front end (20) has an initial peripheral cross-section dimension (C) essentially corresponding to the main peripheral cross-section dimension (B) of the gearbox (10); - a rear end (22) located in connection with the propeller hub (14), where said rear end (22) has a connecting peripheral cross-section dimension (D) essentially corresponding to the main peripheral cross-section dimension (A) of the propeller hub (14). The invention is distinguished in particular by the fact that the transition cone (18) includes a bulb-shaped shoulder part (24) located between said front end (20) and rear end (22), the largest peripheral cross-section dimension (E) of which exceeds the initial peripheral cross-section dimension (C) of the transition cone (18).

摘要： Main rotor blades of the dual, counter-rotating, rigid coaxial rotor system exhibit a unique unconventional combination of positive and negative twist gradients in which the rotor system rotor Figure of Merit (hover efficiency) is improved by providing a dissimilar twist distribution between the lower rotor blade and the upper rotor blades. This improvement is specifically a result of reduced profile drag of the lower rotor system, achieved by driving the effective operating condition of the lower rotor blades to be similar to the upper rotor blade such that the tip drag losses of the lower main rotor have been reduced considerably using a mathematically vigorous approach. While minimal induced power consumption resulted due to the dissimilar lower main rotor twist, a significant profile power benefit is realized, resulting in the improved hover efficiency with essentially no reduction in rotor forward flight performance.

摘要： A propeller for a boat includes a propeller shaft(20) having a shaft hole, a shaft sleeve(30) mounted in the shaft hole(26) of the propeller shaft and provided with a metal core(32) with a through hole for insertion of a driving shaft of the boat, and a shock-absorbing member(34) covering an outer surface of the metal and having an outer surface contacted with an inner surface of the propeller shaft that surrounds the shaft hole(26); and a lock unit(40) mounted on the driving shaft for fixing the driving shaft in the through hole of the shaft sleeve(30), so that the propeller is rotatable by the driving shaft. When the propeller bumps hard things during rotation to result in vibration to the propeller, the shock-absorbing member can absorb the vibration so as to protect the driving shaft from damage.
