Aerospace Instrument-Making Annotation << Back METHODS FOR INCREASING THE EFFICIENCY OF THE ON-BOARD FLIGHT SAFETY SYSTEM OF A MANEUVERABLE AIRCRAFT DURING COMBAT MANEUVERING IN LOW-ALTITUDE FLIGHT MODE A.S. Leontyev, S.P. Poluektov, V.A. Malyshev The article considers one of the approaches to solve the problem of ensuring the safety of a maneuverable aircraft low-altitude flight at the stage of combat maneuvering when overcoming the enemy air defense. The results of flights simulating at the extremely low altitude for various terrain and conditions for a flight task performing are presented. A method of quantitative assessment of a flight situation danger on the basis of an informative parameter is proposed - the error of a given flight altitude maintaining. The law of the error distribution of maintaining a given flight altitude in the form of a two-parameter gamma distribution has been substantiated. The technique of the on-board system efficiency increasing for ensuring the safety of a maneuverable aircraft flight during combat maneuvering on the basis of adaptive control methods is proposed. Keywords: low-altitude flight, flight safety, a flight situation hazard assessment, adaptive control, error of maintaining a given altitude, terrain relief, the law of a random value distribution.
