Aerospace Instrument-Making Annotation << Back RADAR ASSESSMENT OF PARAMETERS OF FLIGHT OF THE AIRCRAFT IN THE CONDITIONS OF ITS FLUCTUATIONS CAUSED BY INFLUENCE OF CASUAL TURBULENT AIR STREAMS Yu.V. Moshchensky, B.M. Klimashov In article questions of influence of turbulence of an air stream on results of radar measurements of traveling speed of flight of the aircraft on Doppler frequency are considered. Change of an angle of attack of the aircraft under the influence of a casual component of speed of a wind is analysed. Fluctuation of the aircraft is considered only in the vertical plane, as most influencing results of radar measurement of traveling speed taking into account forces and the moments influencing flight of the device in the vertical plane. Expressions for a population mean and dispersion of the normal acceleration defining the loadings operating in flight on the aircraft are received. Recommendations about a choice of some parameters of automatic control at which achievement of such condition of flight of the aircraft at which it will poorly react to the reasons causing it fluctuations is possible are provided. For ensuring the demanded accuracy of an assessment of high-speed characteristics of the aircraft on Dopler`s frequency it is offered to enter compensation of changes of normal acceleration as functions of parameters of flight of the aircraft. Key words: aircraft, radar, Doppler frequency, airflow, turbulence. Contacts: E-mail: bmkl@citydom.ru, E-mail: yvmos@yandex.ru.ru Pp. 12-20.
