Abstract
An airscrew is composed of a hub, a connecting blade (an airscrew blade), rotary wings etc. wherein the connecting blade (the airscrew blade) directly connects a ring with the hub and is arranged with rotary wings outwards on the basis of the ring, once the ring number is larger, the extended rotary wings are more. The airscrew can be arranged with more rotary wings in the same rotary radius to obtain the larger pulling force, The airscrew can be used for the airplane, the helicopter and the ship.
Description
The present invention relates to a kind of propeller cavitation, vane type spiral oar, rotary wing type propeller cavitation are arranged on the market.
The purpose of this invention is to provide a kind of propeller cavitation that under certain rotating speed, obtains big Driving force with less turning radius.Can be used for aircraft, helicopter, boats and ships, submarine.
The object of the present invention is achieved like this: the present invention's propeller cavitation is by propeller hub, having helical blade to be connected between formations such as blade, the aircraft wing, connecting ring, first ring and the propeller hub, is that the basis is outwards set up a plurality of aircraft wings (rotor blade) and can also be set up second ring, the 3rd and encircle so that outwards set up more rotor blade with the ring.
The connecting ring sectional shape can have multiple choices, as pipe, elliptical tube, the type of flowing through pipe etc.
The shape of blade can be with reference to existing propeller blade design.
Advantage of the present invention because rotor can be installed on the bigger ring of diameter, just can be provided with more rotor like this in same turning radius.Thereby obtain bigger push-pull effort.Can prepare the helicopter of tens tons of carrying capacity.
The invention will be further described below in conjunction with drawings and Examples.
This figure is the example explanation with the monocycle propeller cavitation only.Propeller blade and rotor quantity only are reference among this figure.
Fig. 1 is a plan view, and Fig. 2 is a sectional view, and Fig. 3, Fig. 4 are the rotor sectional shape.Fig. 5 is the helical blade sectional shape.Here rotor is a variable cross section.
Among Fig. 1: 1, propeller hub, 2, helical blade, 3, rotor.
Shortcoming of the present invention: manufacturability is complicated.
Advantage of the present invention: thrust is big.
Claims (4)
1. the present invention relates to a kind of propeller cavitation, it by propeller hub, connect blade (helical blade), rotor etc. and form, connect blade (vane) propeller hub directly be connected with ring, it is characterized in that: be basicly outside encircling, to be radiation-like and to set up a plurality of aircraft wing rotors with the ring.
2. propeller cavitation according to claim 1 is characterized in that: the cross section of rotor is a variable cross section, and its cross section increases from inside to outside.
