In aviation engines and aircraft, gearboxes generally provide power transmission and speed conversion. Particularly in helicopters, the main gearbox (MGB – Main Gearbox), intermediate gearbox (IGB – Intermediate Gearbox), and tail gearbox (TGB – Tail Gearbox) are critical components that transmit the power generated by the engine to the rotors and other systems. These gearboxes are exposed to challenging operating conditions such as high power density, extreme temperatures, and vibrations. Therefore, the reliability and performance of gearboxes are vital for the overall safety and operational efficiency of aircraft and aviation engines.

Comprehensive test systems are required to evaluate the performance and durability of gearboxes. These test systems simulate the actual operating conditions of gearboxes to determine the reliability and lifespan of the components. During testing, critical parameters such as torque, speed, vibration levels, oil pressure, temperature distribution, and wear rates of the gearboxes are monitored.

Gearbox test systems may require a highly sophisticated infrastructure depending on the capacity of the test item. Especially for testing high-power gearboxes, drive-line systems are established by integrating components from various disciplines, ranging from medium-voltage transformer equipment to seismic foundations. Real-time, high-speed dynamic control, precise data acquisition, and analysis are crucial for the safe execution of gearbox test operations.
