A better performance , , investigation and testing can be conducted in an engine test cell. Altogether, a total of three engine tests were performed by varying engine speed from 55 percent rpm to 75 percent rpm. Performance data obtained include the engine's torque, propeller speed, fuel flow rate, and inter-turbine temperature. They were captured by using data acquisition software from AeroTrain Corp. An averaging was done to the data in order to study engine shaft horsepower, specific fuel consumption, and thermal efficiency. From the result of manual calculation, the engine can produce power up to 34.8 kW while running at 75 percent rpm. The specific fuel consumption is 7.07 kgikW-hr while the thermal efficiency is at 1.19 percent. On the other hand, the data acquisition system shows that the engine managed to deliver 89.5 kW of power, 3.15 kg/kW-hr of specific fuel consumption and thermal efficiency of 19.5 percent. It was found that the results of manual calculation were significantly lower than the one obtained using the software with 88 percent different in shaft horsepower and 77 percent different in specific fuel consumption. Although the current engine performance is acceptable and satisfactory to be used for aircraft propulsion education, a safer and more reliable testing arrangement is still needed. Considering that a proper test facility will be essential to obtain a highly accurate result on the engine performance, an engine test cell was proposed to be built.
