Measurement of flight parameters in terms of toxic emissions of the aircraft radial engine ASz62-IR

摘要

This paper investigates toxic emissions emitted by ASz62-IR radial engine under training flight conditions. The registered selected flight parameters enabled the distribution and share of operating times in given stages of engine operation. The individual toxic substances were calculated in line with an AVL BOOST model of this engine. The results of the chassis dynamometer measurements performed at WSK PZL-KALISZ S.A., an engine manufacturer, enabled us to calibrate the model in terms of its performance, i.e. torque and overall efficiency as a propeller characteristics. Later, a model for toxic emissions was calibrated. Defined by crankshaft speed and intake manifold air pressure, operating points reflect real flight values. For each case study, mass flow rates of individual toxic substances were calculated. The distribution of operating times in individual stages of the operation of Antonov An-2's engine registered during a training flight enabled us to calculate a total mass of toxic substances.
