Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings.

[0008] this invention( figure 1 1 is a plane straight blade), ( figure 1 Middle 2 is the ring on the top of the blade), the ring on the top of the blade welds the blades together to prevent the blade from bending, and the ring will reduce the ineffective work at the top when the blade rotates at high speed. When the present invention is used in aeroengines and gas turbines, the ring at the top is beneficial for sealing. Because it is an integral blade, the requirements for the blade material are not high.

Abstract

The invention is an axial flow plane linear integral blade which is suitable for an aviation engine, a gas turbine, a axial-flow blower fan and a boat propeller.

Description

technical field [0001] The invention relates to an axial-flow planar linear integral blade. Background technique [0002] At present, aeroengines, gas turbines, axial fans and marine propellers use small arc blades. Humans have found that the smaller the arc of the blade, the less rotational resistance and noise, and the smaller the arc of the blade, the higher the efficiency. However, the smaller the arc of the blade, the lower its ability to resist bending during high-speed rotation. Therefore, human beings are constantly developing high-strength materials to manufacture smaller arc blades. This arc-shaped blade forms a With a certain thickness, small curved blades will generate turbulence as the speed increases, and turbulence will increase the noise and resistance of the blades. Contents of the invention [0003] The blade of the present invention is designed as a flat and straight overall shape without radians. The purpose is to reduce the turbulence during high-spe...
