Matching of aerodynamic databank with flight test data –longitudinal dynamics

Abstract

© 2016 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.The Flight Simulator (FS) is a key aspect of the traditional aeronautical industry and the general aviation. In the general aviation, the flight simulator contributes to decrease pilot training costs and keep safety the aviation. In the case of traditional industries such as Embraer, Boeing and Airbus, and beyond that, the FS avoid delays and decrease the costs in development of new aircraft. Thus, the aeronautical industry has invested hardly on modeling and simulation (M&S). The objective of this paper is to describe the process of updating the longitudinal aerodynamic coefficients from aerodynamic model of the FS using flight test data in order to establish a model in according with aviation rules. This process is called as aerodynamic matching, and has presented very satisfactory results in aeronautical industry. The methodology used and proposed here is one more tool to model with precision the flight dynamics of airplanes.
