The blade angle on fixed-pitch propellers is set for only one flight regime, and this restriction limits their performance.
Blade angle (o).
A higher exit blade angle was suggested by the researchers.
The blade angle 43°/26° has the best aerodynamic performance.
The blade angle 40°/26° is the second and the blade angle 43°/24° is the last.
In order to force the blade angle β tracks the reference blade angle (beta_{text{in}}), The pitch of the blades is changed by a hydraulic/mechanical actuator.
When the second blade angle is 26°, the static pressure also increases with the increase of the first blade angle from 40° to 43°.
When the first blade angle is 43°, the static pressure increases with the increase of the second blade angle from 24° to 26°.
Li (2011) reported effect of exit blade angle, viscosity and roughness by CFD simulations, but the effect of inlet and outlet blade angle on roughness was not included.
With the increase in blade angle, the pressure difference between outlet and inlet increases.
Increase in exit blade angle increases the hydraulic efficiency till the design point.
