DAMPING OF OSCILLATIONS IN FLIGHT CONTROL CIRCUITS OF SCHOOL AND TRAINING AIRCRAFT
Journal Title: INCAS BULLETIN - Year 2010, Vol 2, Issue 1
Abstract
The specific developments of Dutch roll mode have shown a number of flight dynamics deficiencies, prevailing in aircraft with fixed (non-assisted) controls in which the damping factor is at level 2. The project deals with the lateral motion damping (damper of gyration) issue according to the flight regulations, for an envelope as wide as possible, but mainly referring to missions involving the Dutch roll type developments. The undertaken analysis takes as a reference the school and training aircraft IAR – 99. The execution equipment, an actuator assisted by a servo valve, ensures the system efficiency of self-stabilization system SAS providing low execution times and high precision. The relationship between the flight quality parameters related to characteristics of lateral-directional motion modes, depending on gravimetric-inertial and aerodynamic parameters of the airplane is envisaged to meet the regular levels of flying qualities. The proposed calculation method can be used both for flight qualitative analysis and for defining the overall conditions for meeting the quality flight regulations. These conditions can serve as a basis for assessing the possibilities to remedy the above-mentioned deficiencies mater.
