| Sumario: | [EN] While fixed, unactuated rotor tilt is increasingly utilised in commercial multi-rotor unmanned aerial vehicles (UAV), its impact on forward flight performance remains poorly documented in the literature. The current work addresses this gap in the literature by systematically quantifying the performance trade-offs of rotor tilt across various airspeeds. Furthermore, a novel rotor configuration is proposed to mitigate some of the tilted rotor configuration¿s inherent drawbacks. The different configurations are evaluated using a computationally affordable numerical approach that combines steady-state computational fluid dynamics (CFD) simulations, a simple proportional¿integral (P¿I) trimming algorithm, and actuator disk rotor modelling (ADM). The findings reveal that the aircraft¿s power requirements can be reduced by more than 29% for airspeeds greater than 20 m/s, while its range can be increased by up to 22% with the alternative rotor configurations. However, the modifications were found to have a significantly lesser impact on endurance, as only a 2.9% increase is noted at best. |
