Figures 1 to 5 relate to a propeller as an embodiment of the present invention. Figure 1 is a sectional view of the propeller blade, and Figure 2 is the distance from the leading edge of the propeller blade to the maximum value of warpage. Ratio C' between C' and chord length C
/C and the ratio r/R of the propeller radius R to the distance r from the propeller center. Figure 3 shows the distance B from the leading edge of the propeller blade to the maximum blade thickness. and the ratio B/C of the chord length C, and the ratio r/ of the distance r from the propeller center to the propeller radius R.
Figure 4 shows the relationship between the ratio C'/C between the distance C' from the leading edge of the propeller blade to the maximum value of warpage and the chord length C, and the fluctuating pressure. The graph shown in Figure 5 is a graph showing the pressure distribution on the suction surface of the propeller blade.
The figure is a pressure distribution diagram on the suction surface of a conventional propeller blade. 1...Propeller blade, 1a...Blade leading edge, 1b...Blade trailing edge, 2...Blade chord line, 3...Skeletal line, B...Distance of maximum blade thickness from the blade leading edge, C...Blade chord length, C ′...Distance from the blade leading edge to the position of maximum warpage, d...Blade thickness, f...

プロペラ。 In a propeller, the distance C' from the leading edge of the blade at the position of the maximum warp and the blade chord of the propeller blade of the same propeller are measured by the distance C' from the leading edge of the blade at the position of the maximum warpage, with respect to a cross section of the propeller blade taken along a cylindrical surface with the propeller axis center line as the rotation axis. The distribution curve of the propeller blade in the radial direction of the ratio C'/C to the length C is 0.6 when the radius of the propeller is R.
It has a convex shape with a maximum value of R ~ 0.7R,
The distribution curve in the radial direction of the propeller blade of the ratio B/C of the distance B from the leading edge of the blade at the position of the maximum blade thickness to the chord length C is 0.6R when the radius of the propeller is R It is characterized by being formed to have a convex shape with a maximum value of ~0.7R,
propeller.
