WebThere have been at least three attempts to measure flow-induced pressures on rotating propeller blades. The first, by Bushnell et al. [259] was conducted to understand blade pressures on a new concept high-speed propeller. This work was followed by Minniti et al. [244,245] and Muench [145] for the purpose of examining effects of turbulent inflow. The … WebA cross-section of a typical propeller blade is shown in Figure 4. This section or blade element is an airfoil comparable to a cross-section of an aircraft wing. The blade back is the cambered or curved side of the …
