Abstract

Main idea of power scheduling for aero-engines is to decompose the complex nonlinear energy management and is to cover each break point in all operating conditions by digital engine control unit. In the current study, dynamic energetic and performance measures of an experimental small target drone turbojet engine are calculated at various shaft speeds in test-cell. In this context, some experiment test steps were conducted to measure the performance parameters of the engine at different shaft speeds. With the help of the calculated parameters, efficiencies, power and energy indexes of the engine are also determined. According to analysis, wasted power varies between 7.69 kW and 259.61 kW, while total power of the fluid is 10.2 kW at 25000 RPM and reaches 331.66 kW at 47500 RPM. As for engine efficiency results, with increasing RPM, thermal efficiency is strongly varying with 18.33%, whereas the change ratio of propulsive efficiency stays modest level with 5.17%. As a conclusion, it is expected that these assessments can be employed in the control law design of similar power system controller and also to increase the efficiency of existing systems.
