Abstract
A cross section camber ratio nonlinear distributed marine propeller, which belongs to the filed of marine equipment, particularly relates to a propeller improved structure. The utility model provides a cross section camber ratio nonlinear distributed marine propeller which can effectively delay the separation of the cavity bubble, and prolong the service life thereof. The utility model comprises a boss and blades, and has the main points of the structure that blades are arranged on the boss, and the cross section camber ratio distribution adopts the irregular nonlinear distribution.
Description
Technical field
The utility model belongs to the field of marine equipment, particularly relates to a kind of improvement of propeller arrangement.
Background technology
The cross section camber ratio of so-called marine propeller is meant the camber in leaf cross section and the ratio of leaf cross section span; The distribution form of the cross section camber ratio of general marine propeller is that the line style of rule distributes or rambling distribution; This layout tends to quicken the separation of cavity, thereby increases the weight of to separate the corrosion of explosion to propeller blade because of cavity.
The utility model content
The utility model is exactly at the problems referred to above, provides a kind of and can effectively postpone the separation of cavity, and can prolong the propeller blade cross section camber ratio nonlinear Distribution formula marine propeller in service life.
The technical scheme that the utility model adopted: the utility model comprises wheel hub, blade, and its structural feature is that wheel hub is provided with blade, and the distribution form of described blade cross section camber ratio is irregular non-linear distribution.
The utility model beneficial effect:
The distribution form of the cross section camber ratio of the utility model blade is that irregular non-linearity distributes; Such structure setting can keep under the immovable situation of various main screw propeller parameters, and actv. very postpones the separation of cavity, thereby alleviates because of the corrosion of cavity separation explosion to the utility model blade.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model comprises wheel hub 1, blade 4, and wheel hub 1 is provided with blade 4, and the distribution form of described blade 4 cross sections 3 cambers, 2 ratios is irregular non-linear distribution.
The distribution form of described blade 4 cross sections 3 cambers, 2 ratios is that smooth curve distributes.
Claims (2)
1. a cross section camber ratio nonlinear Distribution formula marine propeller comprises wheel hub (1), blade (4), it is characterized in that wheel hub (1) is provided with blade (4), and the distribution form of described blade (4) cross section (3) camber (2) ratio is irregular non-linear distribution.
2. a kind of cross section according to claim 1 camber ratio nonlinear Distribution formula marine propeller, the distribution form that it is characterized in that blade (4) cross section (3) camber (2) ratio are that smooth curve distributes.
