phase mapping of engine parameters - Opis:
- This paper presents a new approach to the study of events/cases of the use of so-called air mapping phase. The examinations were carried out by means of the selective method on the basis of data for basic operational parameters acquired from the both driving units of the W-3 "Sokół" helicopter. The analysis covered quality of information received from the S2-3a on-board recorder of flight parameters, in particular its resolution and recording frequency. Then it was possible to plot waveforms for variation of the recorded parameters associated with operation of the helicopter engines and its rotor. The waveforms were used to determine the most important fragments suitable for detailed analysis of variations exercised by basic parameters and to check them against the Operation Manual for flights of the W-3 helicopter. The selected operation parameters were used for phase imaging (development of phase portraits), which served as the basis to assess dynamic properties of the parameters variations. The final component of the study consisted in discussion of the obtained results with presentation of conclusions. It is infeasible to monitor technical condition of the package joint between the transmission shaft and the PZL-10W aircraft. It is necessary to install additional sensors and gauges intended to improve accuracy and frequency of parameter readouts. Only sufficient amount of information shall enable application of the phase imaging method to efficient monitoring of technical and emergency operating conditions of aircraft engines.
