Multi-Criteria Propeller Design App (MCDM)

Abstract

This research presents a Python-based Multi-Criteria Decision-Making (MCDM) application for propeller design in civil and light aviation aircraft, integrating a structured logical process that evaluates multiple parameters, including aircraft category, engine type and power, environmental conditions, and priorities such as weight, noise, and cost. Based on EASA Module 17 – Propeller, the app recommends optimal propeller configurations, including blade material, pitch type, actuation method, anti-icing system, blade count, and rotation strategy, while ensuring compatibility between subsystems and preventing critical mistakes such as unsafe material-power combinations, incorrect pitch selection, or improper anti-icing systems. The system also accounts for operational factors like critical engine effects and noise mitigation strategies such as synchrophasing and synchronization, balancing efficiency, performance, and safety. By combining these factors in a multi-criteria framework, the tool provides designers, technicians, and students with reliable guidance to explore feasible propeller designs while maintaining operational safety and system efficiency.
