High precision small propeller
You are welcomed to come to our factory to buy the latest selling, low price, and high-quality High precision small propeller. We look forward to cooperating with you. The high-precision small propeller contains several identical blades, one of which is obtained by rotating the other blade 180 degrees around the axis of rotation, and each blade is composed of two curved surfaces: the upper surface and the lower surface; At the tip of the propeller, the upper surface curved surface is always convex from the leading edge to the trailing edge; from the root to 50% of the radius, the lower surface curved surface shows a downward convex shape.

Product introduction
1. The relative thickness of small propeller blades gradually decreases from the rotating shaft to the tip; the maximum relative thickness is 30%, the relative thickness at 50% radius is 8.67%, and the relative thickness at 60% radius is 7.07%, 70% The relative thickness is 6.87% at the radius, 6.04% at the 80% radius, 4.55% at the 90% radius, and 2.07% at the tip. From the propeller root to the propeller tip, the relative thickness and profile twist angle gradually decrease, and the profile chord length increases first and then decreases.
2. The trailing edge of the small propeller blade has a relative thickness, and the relative thickness gradually decreases from 50% radius to the blade tip. It is characterized in that, from 50% of the radius to the tip of the propeller, the curved surface of the lower surface presents a downward convex shape at 10% of the chord length of the leading edge, and is concave from 10% of the chord length to the trailing edge, and the degree of concave is from 50%. The radius gradually increases to the tip of the blade; the chord length gradually increases from the rotation axis to the 50% radius of the blade; from the 50% radius to the tip, the chord length gradually decreases; the maximum chord length is at 50% radius, the chord length gradually increases The length is 15% of the radius, the minimum chord is at the tip of the blade, and its chord is 6% of the radius. The twist angle of the blade profile gradually decreases from the root to the tip, the twist angle at the root is 40°, the twist angle at 50% radius is 22.5°, and the twist angle at the tip is 11°.
