About
In recent years, propellers have gained popularity due to the flourishing of uncrewed air vehicles, urban air mobility, and electric propulsion systems. The propeller’s design cycle is not different from other engineering design processes. Starting with defining the basic requirements. Then, various analyses are implemented into a design framework. This includes aerodynamics, structure, acoustics, engine matching, vehicle interaction, and performance analyses.
While analysis methods for most of these disciplines remained unchanged during the last decades, the design method improved substantially by harnessing the capabilities of multidisciplinary design optimization tools. Advanced optimization algorithms use this framework to search for suitable solutions. The optimized set of designs is the basis for deciding which design to manufacture. Finally, after manufacturing, the validation process of the chosen designs is used as proof of design.
The talk will review some of the design process’s challenges and solutions and demonstrate this complex, multi-objective, multi-constraint design problem. From time to time, exotic and odd configurations are suggested by ignoring basic engineering principles and neglecting the proper engineering design procedure. The talk will demonstrate this for several quasi-attractive, unorthodox propeller designs.
