SIMULATION MODEL FOR CALCULATING THE PROBABILITY OF AIRBORNE GUIDANCE ON A PURPOSE WITH THE APPLICATION OF THE METHOD OF AIMING TO A FIRST POINT OF MEETING

Abstract

Leading world states are re-equipping their aircraft fleet with multifunctional aircraft, modernizing aircraft in service, developing and purchasing a new generation of guided aircraft weapons. The main features of such aircraft are: reduction of unmasking signs of their use in all wavelength ranges (radar, infrared, ultraviolet, visible, acoustic); ensuring great maneuverability by equipping engines with thrust vector deflection systems and using a ratchet aerodynamic scheme; ensuring a significant combat radius of action; increasing the efficiency of integrated on-board radio-electronic equipment, namely: full situational awareness (tactical, navigation, radio-electronic situation, technical condition of on-board systems); the ability to select and group targets by priority of threats, automatic detection and suppression of enemy radio-electronic means; automatic control of the radiation modes of onboard facilities in order to ensure low visibility of the aircraft; expansion of the range of application of high-precision aircraft weapons for various purposes.

In Ukraine, measures to modernize military aviation equipment and extend its resources and service life fundamentally do not ensure the preservation of military aviation in the future, but only temporarily prevent a reduction in the number and decrease in capabilities when solving problems by existing aviation groupings. When choosing a rational version of a multifunctional fighter, such efficiency criteria should be taken into account as a tactical advantage in air combat (including the presence of Stealth technologies, which are an obligatory element of fifth generation combat aircraft, the possibility of simultaneous firing of several targets), the likelihood of being hit by high-precision strikes against ground targets (including the simultaneous shelling of several targets), cost and resource indicators. The effectiveness of an attack on air targets by a fighter is to a decisive extent determined by the formation of a guidance method on board. Of the target guidance methods used in the onboard systems of fighters when using medium / long-range missiles, one can single out such as the attack curve, parallel approach, the combined homing method (combines the positive qualities of direct approach methods and the attack curve), the biased zone guidance method start-up, etc. The article provides a model for calculating the probability of airborne guidance to an unobtrusive target by the method of parallel approach. An important feature of this method is the practical straightness of the trajectory of the fighter when aiming at a non-maneuvering target. This is the implementation of the maximum range of action of the electronic control system with the minimum consumption of energy and guidance time.
