Method for avoiding missile attack of large aircraft

Abstract

The invention provides a method for avoiding an attack of a large aircraft. The method comprises the following steps: detecting whether there is no missile in a predetermined area; when there is a missile, judging whether a missile section target is a large aircraft or not; when no missile exists in the area or the target of the missile does not point to the large aircraft, the large aircraft normally executes a predetermined task; when the target of the guided missile section is a large aircraft, judging the coming direction of the guided missile, constructing a fuzzy inference rule according to the coming direction of the guided missile and the aircraft speed, and controlling the large aircraft to perform corresponding maneuvering actions by the aircraft according to the constructed fuzzy inference rule, or accelerating the flight of the large aircraft and getting rid of the guided missile by adopting an acceleration mode; then, whether the missile distance is smaller than a first preset value or not is judged, if yes, the large aircraft conducts diving S maneuver to avoid attacks, and if not, the original flight state is kept; then, whether the missile distance is smaller than a second preset value or not is judged, if yes, the large aircraft adopts tail-section avoidance, and if not, the large aircraft keeps the original flight state.

Description

technical field [0001] The present application belongs to the technical field of flight control, and particularly relates to a method for avoiding attacks on large aircraft. Background technique [0002] In modern air combat, air-to-air missile technology has emerged from scratch and has now become the main weapon in air combat, which has an important impact on air combat mode. Following the combat concept of "save yourself, shoot down the opponent, and gain air supremacy" in air combat, reasonable missile evasion is an essential homework in modern air combat. [0003] In recent years, scholars at home and abroad have conducted a lot of research on missile evasion strategies in air combat: Japanese scholars Imado and Miwa analyzed several maneuvering methods for fighter jets to avoid air-to-air missiles, and analyzed their applications for continuous maximum overload turning and linear acceleration maneuvers. Boundary conditions, the optimal maneuvering combination and mane...
