“…For machines with rotating components, this problem is often optimised by increasing their rotational speed [22]. Due to the impossibility of perfectly balanced rotors, some energy is converted into oscillations [1,14,19]. Unwanted oscillations can cause damage or failure, so it is important to monitor them properly at all times.…”

This paper proposes the use of vibroacoustic signal parameters to estimate the fuel consumption of a miniature GTM-400 engine. The method for testing engine vibrations is presented, followed by an analysis of the results obtained. Two vibration point measures were selected to build a fuel consumption model. The models obtained were verified, after which those that best describe the real fuel consumption of the engine were selected. The paper proves that the vibration signal, in addition to its applications in jet engine diagnostics, can be used to determine engine performance, which can contribute to reducing the complexity of construction and increasing the economics of engine operation.
