    Influence of the pilot on the modal parameters of the control system lightweight aircraft

  • Original language description

    Lightweight Aircraft dynamic properties, especially stability and flutter, are of great importance. It has been shown that pilot influence on aircraft dynamic properties is non-negligible, due to the mechanical link between aircraft and pilot through control stick. The paper introduces experimental determination of pilot dynamic model. The main goal is investigation of differences between setup with pilot holding the aircraft control stick and free control stick in focus on dynamical characteristics of aircraft longitudinal primary control system. Next goal is description of pilot modal properties in range from 1 Hz to 70 Hz with sample of various persons. Recently there are only two setups for flutter tests, free control and fixed control stick (rigidly to aircraft body). There are many publications in the area of human dynamic properties and their influence on mechanical systems. But all of them describe human behaviour in the range up to 10 Hz, as they are focused on dynamical flight response, not on the dynamical response of aircraft structure. Other publications are focused on responses with working heavy tools such as drilling hammers and dropper, without human model, but they also concentrate on different frequency range. Experimental stand was created to measure pilot influence. Pilot characteristics were measured by force sensor and accelerometers. Pilot’s state space model is identified based on experimental data.
