Then, the performance of the propulsion system including the full-scale propeller is obtained by the full-scale testing system at relatively low altitude.
The structure of dynamometer for the full-scale propeller test is shown in Figure 3.
Figure 3 Schematic diagram of full-scale propeller dynamometer
Unlike the full-scale propeller test, the experimental data of the scaled model test are easily affected by the vibration of the system due to the small magnitude of the aerodynamic force.
Validation of the full-scale propeller testing system has been attempted with a 4.6-m propeller model for a high-altitude vehicle both in static (V = 0 m/s) and dynamic (V = 5 m/s) cases.
