Desenvolvimento de uma bancada de teste de motores para aeromodelos destinados a competição SAE Aerodesign

Abstract

This work presents the development of a test bench designed for the characterization of propulsion systems used in model aircraft, with an emphasis on measuring parameters such as thrust, torque, and rotational speed of electric motors, especially those applied in academic competitions like SAE Aerodesign. Based on previously defined requirements, a new structural layout was proposed for the bench. The project incorporated fluid mechanics concepts to define boundary conditions, as well as fundamentals of solid mechanics for the static structural design. Structural modeling and simulation were performed in the CAD/CAE environment of PTC Creo, in order to optimize the structure under operational loads. Based on the boundary conditions, load cells compatible with the project specifications were selected. The final design integrates mounting points, sensors, and peripheral components in a functional and modular manner.
