Godovanyuk G. Definition of parameters of motion of a flight vehicle at investigation of air accidents

The algorithm and method of an authentic evaluation of kinamatics parameters in space motion FV is developed. The problem of an evaluation is reduced to the solution of a problem of series conditional parametric optimization. On an example of the analysis of an air accident which had place on landing of a plane the functionability and efficiency of the developed algorithm was confirmed.The non-linear version of a modified Kalman filter permitting to define an evaluations as is offered input and output variables at availability in measurements of additive errors as normal random processes, when the equations of communication represent stochastic differential equations. The method and algorithm of an evaluation of landing weight and centre-of-gravity positions of a plane at landing is developed at fundamentals of data means of the objective control and uses of procedures of mathematical modelling. The functionability is confirmed on an example of the analysis of a particular air accident.
