The objectives are efficiency ratio and thrust coefficient.
where is called the thrust coefficient and in general is a function of propeller design, Re, and.
Moreover, the fluctuations of thrust coefficient can be controlled by collective pitch control.
Through optimization of blade design, efficiency increased by 1% while the thrust coefficient decreased by 7.5%.
The blade model performance was estimated in terms of rotation torque coefficient and thrust coefficient.
The thrust coefficient was observed to be significantly reduced, and the efficiency diminished.
Results show that the initial arc radius slightly influences the axial thrust coefficient, whereas the variations in the lateral expansion contour, the length and initial expansion angle of the lower cowl significantly affect the axial thrust coefficient.
The results show that the initial arc radius slightly influences the axial thrust coefficient and that the variations in the length and initial expansion angle of the cowl significantly affect the axial thrust coefficient.
However, the axial thrust coefficient, lift and pitching moment all decrease rapidly with the shutdown of the turbine nozzle, and the decreases in axial thrust coefficient, lift and pitching moment are 1.04%, 67.15% and 80.92%, respectively.
From the plasma probe measurements, an upper bound of 0.93 for the thrust coefficient has been derived, while direct thrust measurements have shown a thrust coefficient between 0.8 and 0.9 over the entire thrust range.
The triangle tip turbine performs 4.34% increment in power coefficient and 3.97% increment in thrust coefficient at the optimal TSR.
