Investigation of Pilot Induced Oscillation Tendency and Prediction CriteriaDevelopment

摘要

This report documents the results of work of three Russian institutions directedtowards the development of criteria for analysis and prediction of pilot-induced oscillation (PIO) tendencies. The first section of the report covers work done at the Moscow Aviation Institute to determine some of the basic influences of PIO and develop new criteria or modify existing criteria for the prediction of PIO tendencies. The second section describes work done at the Central Aerohydrodynamic Institute to investigate PIO tendencies utilizing a ground-based simulator to evaluate the effects of feel system dynamics and control sensitivities on PIO tendencies. The third section describes work done at the Gromov Flight Research Institute on the use of TU-154 in-flight simulator to evaluate and validate various criteria for the prediction of PIO tendencies in flight for Class III aircraft.
