MODELING WITH SIMULINK OF FLIGHT INFORMATION PROCESSING

Abstract

Describing information processing using mathematical modeling and using numerical methods is currently one of the most effective ways. Some flight parameters are not recorded explicitly by the onboard recorder, so there is a need to develop a methodology for obtaining these parameters from indirect data contained in the flight data. This article presents technique is proposed in order to obtain the required information contained in these data in an implicit form. A method of using the
data of the flight recorder, which fixes the parameters of the aircraft movement is presented. An original way of combining computer models and flight data is proposed. The mathematical techniques used in the process of identification are described. The purpose of the work is to present simulation computational experiments and determine all the coefficients at different stages. This results in smoothing of errors. High accuracy is required for predictive calculations. For example, when determining the take-off distance. In this case, an analytical solution is applicable, or, if not available, an exact method based on identification data.
This article presents activities results on aircraft take-off weight and engine thrust determination at the take-off run by onboard self-recorder unit data. Mathematical methods applied at the identification process are described. These methods precision value is given.
