Aircraft piston engine load distribution in steady state operating conditions

The article presents the results of analysis operational parameters piston engine CA 912 ULT which is a propulsion system ultralight gyroplane Tercel produced by Aviation Artur Trendak. Research was conducted under normal operating conditions autogyro and data collected from 15 independent tests including total 14 flight hours during training flights. Engine were recorded at 9 Hz each using on-board Fligh Data Recorded system. Collective presented to show statistical analyses individual determining mean values, standard deviations histograms distribution these parameters. included speed, charge pressure, air temperature, oil temperature exhaust temperature. Histograms points defined both speed manifold pressure also determined. Analyses carried out determine contribution steady-state transient operation. It shown that dynamics work in real small. Detailed for conditions. value load index determined its out. are concentrated mainly range idle power above 50% nominal power. most frequent 80%
