Description
Technical field
A kind of new pod propulsion electric propulsion device is the utility model is related to, it uses NACA aerofoil profiles to replace traditional B4-
70 propellers.
Background technology
Before 100 years, people begin to drive propeller to rotate using motor, but motor promotes for a long time
The restriction of prior art condition, gear drive, ac motor speed control technology, maintenance etc. is limited by always all in certain journey
The propeller power of propulsion system is limited on degree.In the 1980s, with power control technology, motor frequency modulation technology etc.
Fast development, ship has begun to use electric power, and as propulsion system, it is that electric propulsion device is a kind of successfully that wherein gondola, which promotes,
Using having become the important propulsion plant of watercraft electric propulsion system now.Podded propulsion system saves hull
Using space, the maneuvering performance for reducing noise and vibration, adding propulsive efficiency, improving ship, therefore, electric power pushes away
Entering system has big advantage, and on merchant navy vessel and Military Warship, podded electric propulsion utensil has high application valency
Value.
Utility model content
The purpose of this utility model is to provide a kind of new pod propulsion electric propulsion device, uses sagitta face as a=0.8,
Thickness NACA66 NACA aerofoil profiles replace traditional B4-70 propeller aerofoil profiles, improve traditional podded electric propulsion device
Performance.
New pod propulsion electric propulsion device of the present utility model is mainly by asymmetrical NACA aerofoil profiles propeller, gondola and rudder
Three parts form.Described gondola uses axial symmetry type gondola, and described rudder uses NACA symmetrical airfoil rudders, i.e. arc above and below aerofoil profile
The symmetrical aerofoil profile of line.Described propeller uses NACA66 aerofoil profiles and a=0.8 is in sagitta face, propulsive efficiency highest under this parameter.
Propeller is arranged at gondola end；By the connection of rudder, gondola is suspended on ship stern bottom, motor is placed with gondola, passes through
The propeller of motor driving gondola end (front end or rear end).It is using the main thought innovation of the structure design：
Being connected by rudder, the gondola for being equipped with NACA66 aerofoil profiles propeller and motor is suspended on ship stern bottom, 360 ° of gondola energy rotates,
Which saves the propeller shafting that tradition uses, and propulsion plant and rudder are combined into an entirety.
The beneficial effects of the utility model are, the performance such as the thrust of NACA66 aerofoil profile podded electric propulsion devices, torque compared with
Traditional B4-70 propellers and common podded electric propulsion device are increased, and the NACA66 aerofoil profiles that sagitta face is a=0.8 are hung
Cabin formula electric propulsion device propulsive efficiency highest.This novel propeller can save space, be easy to full ship preferred arrangement, can improve ship
Comprehensive navigation performance, the degree of modularity is high, is easily installed and safeguards, while can save cabin spaces, reduces the vibration of main frame,
Increase propulsive efficiency, improve the maneuvering performance of ships.
Brief description of the drawings
Fig. 1 is NACA aerofoil profile blade curved surface schematic diagrames；
Fig. 2 is that new pod propulsion electric propulsion device rotates schematic diagram.
1. rudder in figure, 2.NACA66 aerofoil profile propellers, 3. gondolas.
Embodiment
Reference picture 1,2, pod propulsion electric power propeller of the present utility model is by the propeller of NACA aerofoil profiles, gondola and rudder three
Part forms；Described propeller uses NACA66 aerofoil profiles and a=0.8 is in sagitta face, and its blade curved surface such as Fig. 1, propeller is set
Gondola end is placed in, described gondola is connected by above-mentioned rudder, hangs on ship stern bottom, motor, motor are set in gondola
Drive above-mentioned propeller.As shown in Fig. 2 this example propeller by asymmetrical NACA aerofoil profiles propeller, axial symmetry type gondola and
Symmetrical NACA aerofoil profile rudders three parts composition, traditional B4-70 spirals are replaced using sagitta face a=0.8 NACA66 aerofoil profiles
Paddle type, realizes the raising of the hydrodynamic performance such as propeller thrust and torque, and gondola can realize 360 ° of rotations, save simultaneously
Cabin spaces, the vibration of main frame can be reduced, increase propulsive efficiency, improve the maneuvering performance of ships.
