I developed a test setup based on an STM32 microcontroller system to accurately measure the vibration, thrust, and RPM (rotations per minute) values of propellers. The system integrates multiple high-precision sensors, including an Infrared (IR) sensor, Load Cell, Piezoelectric sensor, and Inertial Measurement Unit (IMU), to collect detailed data on propeller behavior during operation.
By processing the data acquired from these sensors, I conducted comprehensive performance analyses of various propellers under different conditions. Additionally, I improved the overall accuracy and reliability of the system by employing a combination of different sensor types and optimizing the real-time data acquisition and analysis processes. This approach enabled precise evaluation and comparison of propeller dynamics, making the setup a valuable tool for testing and validation in aeronautical and mechanical applications.
