Information Technologies for Creating Algorithms and Software for Flight Tests of Aircraft Pre-Production Designs

Abstract

The possibility of using new information technologies for signal processing at the aircraft flight test stage is investigated. Since there are restrictions imposed on flight modes, the identification of parameters of aircraft its equipment is carried out in the conditions of bad observability of the dynamic characteristics. It complicates the problem of ensuring the usability of computing algorithms for solving the systems of equations formed from the results of measurements of the flight parameters. The traditional algorithms are based on the principle of consecutive execution of computing operations. Therefore, the possibility of application of new information technologies for the creation of algorithms with parallel structure is investigated. It will allow to apply parallel computers and to increase speed of information processing. In this case, there is an opportunity to apply more advanced algorithms for the control of dangerous modes of flight. Such problem is solved for the aircraft takeoff run mode. The new information technologies are offered to be realized on the basis of symbolical combinatory computing models
