In the training of future aeronautical engineers, it is essential to bridge theoretical concepts with practical experiences that simulate real-world professional conditions. In this context, during the fifth semester of the Aeronautical Engineering program, 30 students participated in a hands-on activity as part of the course "Fundamentals of Internal Combustion Engines" (FMCI). The central focus of this activity was the inspection of a turbofan engine combustion chamber using a videoscopy test. Theoretical content covered in class included the operation of reciprocating and rotary engines, stoichiometric balance, air-fuel mixture characteristics, and combustion efficiency. Based on this theoretical framework, students analyzed the structure and function of combustion chambers, including their three zones (primary, secondary, and tertiary), and the main operational challenges such as wear, deformation, and the difficulty of inspection without disassembling the engine. To reinforce learning, a videoscopy demonstration was conducted—this is a non-destructive inspection technique widely used in the aeronautical sector that allows the internal condition of critical components to be observed without disassembly. This experience enabled students to apply technical knowledge in a controlled environment, develop observational and analytical skills, understand the importance of predictive maintenance, and appreciate the value of current technological tools in aviation. In doing so, the activity fostered a comprehensive understanding of inspection processes that will enhance their future professional performance.
