Modeling of a Complex Digital Air Data System for Measuring Attitude and Flight Direction of Aircraft

Abstract

The process of measuring attitude, yaw and drift signals of aircraft using aerometric methods becomes especially important during intercontinental flights, when GNSS is inoperative, GNSS denial during intercontinental flights limits attitude and drift measurement. To determine the values of the aircraft’s pitch, roll, yaw angles, by the aerometric system the new method and modified smart probe should be used and a new method using a smart probe within a digital air data system (CDADS) is proposed. Theoretical foundations for the operation of a comprehensive complex digital air data systems are presented and a computer model for determining flight and navigation parameters is compiled, a comparison of the results of modeling the complex digital air data systems computer model and literature data was obtained, a mathematical model and computer simulations are developed obtaining information on flight and navigation signals, including additional parameters such as roll, pitch, yaw, lateral speed, wind velocity, drift angle are compiled, and a computer model simulation is performed.
